Products
[edit]ELCAN is perhaps best known for making the prismatic C79 optical sight that is widely used on the Colt Canada C7 and C8, FN Minimi, FN MAG and CZ-805 BREN families of firearms. The C79 is not designed as a sniper sight per se, but is rather intended to be mounted on a variety of service rifles used by regular infantrymen as well as designated marksmen. Unlike the M145, reticle illumination is through tritium gas.
The M145 Machine Gun Optic is a variant of the C79, which is different to the standard version in that ballistic compensation is in the reticle rather than in the mount. Reticle illumination is by a battery-powered LED with eleven brightness settings. It is used by the US military for its M249s and M240s.
ELCAN currently manufactures the "Specter" line of combat optics in a variety of configurations. The Specter 4× Optical Sight, DR 1.5×/6×, DR 1x/4× and TR 1/3/9 are available with a BDC reticle for the 5.56×45mm NATO or the 7.62×51mm NATO.

History
Origins in Ernst Leitz Canada
Ernst Leitz Canada Limited, commonly abbreviated as ELCAN, was established in 1952 in Midland, Ontario, by the German optics firm Ernst Leitz (Wetzlar) GmbH, the predecessor to Leica Camera AG, as a subsidiary focused on optical assembly and production to serve North American markets.[2][5] The facility initially operated out of a repurposed curling rink, emphasizing the assembly of cameras, lenses, and related optical components using precision parts shipped from the parent company's Wetzlar headquarters in Germany.[6] This setup leveraged Ernst Leitz's renowned expertise in high-quality glass optics and mechanical engineering, rooted in over a century of Leica's innovations in microscopy and photography.[7] Early operations at Ernst Leitz Canada prioritized export-oriented production, including the adaptation of German designs for local manufacturing efficiencies, while maintaining rigorous standards for lens grinding, coating, and alignment.[2] By the mid-1950s, the company had expanded beyond mere assembly to in-house optics fabrication, incorporating talent like lens designer Walter Mandler, who contributed to custom focal length developments starting from his earlier work in 1947.[5] This growth reflected a strategic shift toward self-sufficiency, enabling ELCAN to produce specialized instruments for industrial, scientific, and emerging military applications, distinct from consumer photography.[8] The subsidiary's foundational emphasis on precision engineering laid the groundwork for ELCAN's later diversification into advanced sighting systems, drawing directly from Leica's heritage in durable, high-resolution optics.[9] By 1964, operations in Midland had solidified, with the facility producing components integral to optical devices that prioritized clarity and reliability under demanding conditions.[6] This era marked ELCAN's transition from a regional outpost to a hub for innovative optical technologies, independent yet informed by its German origins.[2]Expansion into Military Optics
Ernst Leitz Canada (ELCAN) began expanding into military optics in the 1960s with contracts for specialized imaging systems, including a high-resolution 35mm camera system for the US Navy based on Leicaflex SL technology.[9] By 1974, the company secured a Canadian government contract to produce 7x50 roof-prism binoculars for inter-service military use, marking early involvement in defense observation equipment.[10] These efforts built on ELCAN's precision optics heritage, applying Leica-derived expertise to ruggedized military applications requiring durability, such as underwater systems and high-speed film imaging.[7] In the 1980s, ELCAN focused on small arms optics, developing sights for the Canadian Forces' C7 and C8 rifles in collaboration with the Defence and Civil Institute of Environmental Medicine (DCIEM), which specified 3.5x magnification, 5-foot drop resistance, and 10-meter water immersion.[11] Prototypes like the Leitz WildCat were tested following the merger with Wild Heerbrugg, leading to advanced roof-prism designs optimized for combat reliability.[11] This period represented a strategic pivot toward weapon-mounted sights, leveraging prior innovations in compact optics for man-portable systems.[12] The expansion culminated in 1991 with the adoption of the ELCAN 3.4x Optical Sight as the C79 by the Canadian military (NSN 1240-21-906-8151), with approximately 65,000 units procured for rifles and carbines.[11] The tritium-illuminated design provided clear sighting in low-light conditions and supported engagements from close to mid-range distances.[13] Subsequent US military evaluations in 1990 for the Advanced Combat Rifle program and later contracts for M145 variants on machine guns expanded ELCAN's reach, delivering sights to allied forces and demonstrating the technology's export viability.[11] By the late 1990s, over 475,000 C79/Specter OS units had been supplied to 40 countries, solidifying ELCAN's position in global defense optics.[14]Acquisition by Raytheon and Integration into RTX
In 1997, Raytheon Company acquired ELCAN Optical Technologies as part of its $9.5 billion merger with Hughes Aircraft Company, which had itself purchased the division from Leica Camera AG in 1995.[15] The merger, announced in January 1997 and completed on December 18, 1997, integrated ELCAN into Raytheon's Network Centric Systems segment, leveraging its expertise in precision military optics for enhanced defense capabilities.[16] This acquisition preserved ELCAN's manufacturing facilities in Midland, Ontario, and expanded its role in producing advanced sighting systems for U.S. and allied forces.[17] Speculation arose in 2011 regarding Raytheon's potential divestiture of ELCAN amid broader portfolio reviews, but no sale materialized, allowing continued investment in its optical technologies.[18] Following the April 2020 merger of Raytheon Company and United Technologies Corporation to form Raytheon Technologies, ELCAN was aligned under the Raytheon business unit, emphasizing vertical integration for design, manufacturing, and testing of high-precision optics.[19] In July 2023, Raytheon Technologies rebranded to RTX Corporation, with ELCAN operating as Raytheon ELCAN Optical Technologies within RTX's intelligence and space segment, focusing on applications such as weapons guidance, targeting, and high-energy laser optics.[1] This integration has supported ongoing contracts, including multi-million-dollar awards for ELCAN Specter DR sights to NATO allies, underscoring sustained operational continuity and resource allocation under RTX's global aerospace and defense framework.[20]Products and Technologies
SpecterDR Dual Role Sights
The SpecterDR Dual Role Sights, produced by Raytheon ELCAN Optical Technologies (an RTX business), are compact prism-based telescopic weapon sights engineered for rapid transitions between close-quarters battle (CQB) and medium-range targeting.[21] The core innovation lies in a dual-field-of-view (DFOV) system activated by an ambidextrous throw lever, switching between 1x magnification for a wide field of view (FOV) suited to target acquisition in dynamic environments and 4x magnification for precise identification at distances up to several hundred meters.[22] This design maintains consistent 70 mm eye relief across both modes, avoiding the parallax and relief compromises common in variable-power optics, and enables instant toggling between a 1x red dot mode for close-quarters engagements and 4x magnification for 100-600 meter ranges, providing significant tactical advantages when mounted on 7.62mm combat rifles.[21][23] Introduced in the early 2000s to address U.S. Special Operations Command requirements for a versatile day optic compatible with image intensification and thermal clip-ons, the SpecterDR mounts on MIL-STD-1913 rails and features a rugged, nitrogen-purged housing resistant to shock, water, and environmental extremes.[24] Key technical specifications for the baseline 1-4x model include a 32 mm objective lens for enhanced low-light performance, a reticle with ballistic drop compensation (BDC) for 7.62mm calibers illuminated by a battery-powered LED (compatible with red or green options), and compatibility with backup iron sights via integrated A-frame or diopter adjustments.[25][23][26] The sight's fixed prism architecture delivers high light transmission rates exceeding 80% and a wide 1x FOV of approximately 24 degrees, outperforming many low-power variable optics in speed and simplicity.[22] Variants expand the lineup for specialized roles: the 1.5-6x model targets machine gunners and designated marksmen, offering a broader 1.5x FOV for situational awareness while providing 6x for extended precision, with updates in 2024 including integrated top Picatinny rails for accessories, improved battery compartments, and Cerakote finishes for corrosion resistance over prior anodizing.[27] Both variants prioritize size, weight, and power optimizations, weighing around 620-700 grams unloaded, to minimize soldier burden while integrating with night vision devices without zero shift.[28] Military adoption has included U.S. Special Operations Forces and Navy units deploying the 1-4x model by 2009 for combat operations requiring seamless day-night transitions.[24] In 2020, the Danish Defence Armed Forces awarded Raytheon a $10.1 million contract for SpecterDR sights tailored for their service rifles, followed by additional multi-million-dollar procurements in 2025 through the NATO Support and Procurement Agency for ongoing fleet sustainment.[29][20] The German Bundeswehr selected the 1-4x variant in 2021 via a Leonardo Germany contract, incorporating Bundeswehr-specific reticle modifications and mounts for G36 and HK416 platforms, with deliveries emphasizing enhanced illumination for European operational theaters.[30] These procurements underscore the sight's reliability in NATO-aligned forces, though field reports note occasional critiques of reticle brightness in extreme glare without auxiliary filters.[31]SpecterOS and Fixed Magnification Optics
The SpecterOS series comprises fixed-power combat optical sights produced by ELCAN Optical Technologies, designed primarily for 5.56mm NATO carbines and rifles in military environments.[32] These prism-based sights offer a single magnification level—typically 3x or 4x—prioritizing ruggedness, optical clarity, and rapid target acquisition without the mechanical complexity of variable or dual-role systems.[33] Unlike the SpecterDR line's switchable fields of view, the SpecterOS maintains a consistent optical path for simplicity and reliability under extreme conditions, including shock resistance up to 450 g-forces and submersion tolerance for 2 hours at 66 feet.[33][21] Key specifications for the SpecterOS 4x model include a 4x magnification, 32mm objective lens, 8mm exit pupil, and 70mm eye relief to enhance situational awareness in dynamic scenarios.[33][34] The field of view measures 6 degrees (approximately 34 feet at 100 yards), with external turret adjustments providing 120 MOA of windage and elevation travel in 0.5 MOA increments per click.[33][12] Reticles feature options such as illuminated crosshairs or chevrons calibrated for 5.56mm ballistics (e.g., 62-grain loads from a 16-inch barrel), incorporating bullet drop compensation (BDC) stadia lines for ranges from 300 to 800 meters.[33][35] Illumination systems vary by variant but commonly use battery power (e.g., DL 1/3N lithium cell, lasting 600–3000 hours) with 10 discrete settings—five for daylight visibility and five for low-light conditions—enabling etched reticle glow without fiber optics for consistent performance across lighting.[33] The 3x model (SpecterOS 3.0) adds a proprietary Rapid Aiming Feature (RAF) integrated into the illuminated reticle, combining a central aiming point with range-finding hashes to support quick close-quarters transitions while retaining medium-range precision.[36][37] Overall dimensions for the 4x unit are approximately 153mm length, 73mm width, and 69mm height, with a weight of 17.4 ounces including the integral mount.[33][38] These fixed magnification optics emphasize low size, weight, and power consumption (SWaP-C) optimizations, making them suitable for man-portable weapons in prolonged field use, though they lack the versatility of higher-power variables for extended ranges beyond 800 meters.[32] Optional top-mounted rails accommodate miniature red dot sights for hybrid close-range augmentation.[39] Independent evaluations highlight the series' superior glass quality and reticle usability in varied lighting, attributing performance to ELCAN's prism design that delivers high resolution without compromising durability.[33][12]Other Precision Optical Systems
ELCAN Optical Technologies produces a range of electro-optical/infrared (EO/IR) sub-systems for platform-mounted turrets and multi-spectral targeting applications, enabling precision engagement of targets in adverse conditions such as low visibility or inclement weather.[1] These systems integrate sensors for detection, tracking, and guidance, supporting missile direction and fire control on ground vehicles, aircraft, and unmanned platforms.[40] In addition to man-portable sights, ELCAN supplies precision optics for high-energy laser (HEL) systems, featuring high laser damage thresholds, ultra-low scatter coatings, and environmental stability to withstand operational stresses.[1] These components facilitate directed-energy weapons for defense against threats like drones or missiles, prioritizing beam quality and thermal management.[1] For aviation, ELCAN provides head-up display (HUD) projectors and sensor suites that deliver fused data for 360-degree situational awareness in fighter cockpits.[1] In 2017, Raytheon ELCAN was selected to manufacture the projector for BAE Systems' Digital Light Engine HUD upgrade on the F-22 Raptor, replacing analog systems to enhance pilot cognition of flight, sensor, and threat data.[41] Similar technology supports EO/IR integration for infrared search and track (IRST) systems, detecting and countering IR signatures from incoming aircraft, helicopters, or UAVs.[1] ELCAN's space-based ISR optics reduce size, weight, power, and cost (SWaP-C) while enabling EO/IR data collection for reconnaissance.[1] These sub-systems incorporate multi-spectral designs and precision alignment techniques, such as diamond-point turning for complex surfaces, to maintain performance in vacuum and extreme temperatures.[1] Applications extend to weapons seekers, where EO/IR components guide precision munitions against dynamic targets.[1]Technical Features and Innovations
Dual Field of View Mechanism
The Dual Field of View (DFOV) mechanism in ELCAN's SpecterDR series represents an integrated optical system that allows instantaneous switching between unity or low magnification for close-quarters engagements and higher magnification for medium-range precision, all housed within a compact, fixed prism-based design. This eliminates the need for separate sights or variable zoom adjustments, maintaining a single point of aim and consistent eye positioning. The switching is actuated by a side-mounted, ambidextrous lever that engages internal cam-driven components to reposition lens groups, effectively altering the optical path length and focal properties without introducing distortion, parallax shift, or deviation from the original zero.[42][31] In the standard 1x/4x configuration, the lever is positioned forward for 4x magnification, providing a field of view (FOV) of 6.5 degrees (approximately 34 feet at 100 yards), suitable for target identification beyond 200 meters, and backward for 1x, expanding the FOV to 26 degrees for rapid target acquisition in dynamic, low-light, or confined environments akin to non-magnified reflex sights. Eye relief remains fixed at 70 mm (2.75 inches) in both modes, with an 8 mm exit pupil ensuring usability across varying lighting conditions via a 32 mm objective lens. The mechanism supports LED-illuminated reticles that scale appropriately—such as a 1.5 MOA dot at 4x reducing to 6 MOA at 1x—while preserving ballistic holdover accuracy without recalibration.[42][43] Variants like the 1.5x/6x model adapt the same lever-actuated principle for enhanced range, yielding an FOV of 16 degrees at 1.5x and 4 degrees at 6x, with switching completed in under one second and no alteration to cheek weld or bore alignment. This design leverages high-efficiency broadband coatings on fixed prisms rather than moving zoom elements, contributing to mechanical simplicity, reduced weight (approximately 670 grams including mount), and resilience in extreme conditions, as validated in military testing for shock, vibration, and environmental sealing.[28][44] The approach prioritizes causal reliability by minimizing failure-prone components, enabling seamless transitions that support tactical adaptability without compromising optical clarity or aiming consistency.[42]Size, Weight, Power, and Cost (SWaP-C) Optimizations
ELCAN Optical Technologies prioritizes SWaP-C in its precision sighting systems to alleviate warfighter load while maintaining performance, integrating features like compact dual-field-of-view optics that consolidate functionality into a single unit rather than requiring separate red-dot and magnified sights.[45] This approach reduces overall system weight and procurement costs by eliminating redundant hardware.[19] Design refinements in the SpecterDR series exemplify size optimizations, including a low-profile illumination switch that halves protrusion from 26.8 mm to 14.9 mm, minimizing snag hazards and enabling integration with rail-mounted accessories without excessive bulk.[45] The unit's dimensions—153 mm length, 68 mm width, and 72 mm height for the 1x/4x model—facilitate mounting on standard rifles while preserving a low center of gravity.[22] Weight reductions stem from material substitutions and component streamlining; the SpecterDR 1x/4x dropped from 640 g to 607 g via switch and alloy modifications, a 5% decrease, while the SpecterOS 4x achieved 17% lighter at 528 g relative to prior iterations.[45] Targeted 10% cuts for the SpecterOS 6x further underscore iterative lightweighting without compromising ruggedness for military environments.[45] Power efficiency improvements involve upgrading from DL1/3N to CR2032 lithium batteries, extending SpecterDR average runtime by 50% to 4,500 hours, which curtails battery logistics and downtime in field operations.[45] Illumination for reticles draws minimal draw—e.g., up to 1,730 hours on near-max settings for 1.5x/6x variants—supporting extended missions with infrequent replacements.[46] Cost optimizations emphasize lifecycle economics, with durable, low-maintenance designs lowering total ownership expenses and bolstering competitiveness in defense bids, as evidenced by multi-million-dollar NATO contracts for SpecterDR deployments.[45][20]| Model | Length (mm) | Weight (g) | Battery Type | Avg.
