Raytheon ELCAN

For more than 160 years, Raytheon ELCAN has been delivering high‐precision optical systems for the most demanding challenges in the world. Across mission, industries and continents, we leverage the depth and breadth of our expertise to drive new standards of quality, innovation and performance.

At Raytheon ELCAN, we think differently to help customers see better and further across any domain and against any challenge.

Cross-market expertise

End‐to‐end capabilities

Vertical Integration

A vertically integrated full‐service partner, we work closely with you to solve any challenge. From concept to prototyping to testing, we ensure efficiencies that enable us to maximize performance, reduce cost and rapidly deliver superior electro‐optical solutions to market.

Vertical integration in high precision optical manufacturing is part of ELCAN’s competitive strategy to reduce cost and increase production yields for our customers. By partnering at the design stage and controlling strategic sourcing through to assembly and testing, ELCAN delivers more predictable and cost‐effective products for our customers.


The design process is an iterative exercise where adjustments need to be made frequently, sometimes to the optical component, sometimes to the mechanical component. Because we design for manufacturability in‐house, specifications can be tailored and modifications made to ensure the most cost‐effective, optimized solution. Design at ELCAN includes optical, mechanical, electronic as well as FEA predictive and thin film coating design. Design engineering are colocated and work closely with production engineering, and assembly and test engineering.


Prototyping enables proof‐of‐concept/process to evaluate a new design to enhance precision and performance prior to entering large‐volume production.


Optical fabrication: ELCAN produces precision optics – from 5 mm to 300 mm in diameter including spherical, aspherical, cynlindrical, freeform and plano optics using more than 630 materials. End-to-end fabrication utilizes advanced computer-controlled technologies and processes including generation and polishing through assembly and test.

Mechanical fabrication: Raytheon ELCAN manages end-to-end fabrication for complex opto-mechanical assemblies including in-house CNC metal machining.

Advanced in-house surface treatment: We perform metal surface treatment in-house, ensuring that strict processes are followed in order to maintain quality and delivery requirements.

Surface treatment finishes include anodizing, hard anodizing, black oxide treatment, passivation, chrome plating, electro-less nickel plating, painting and metal impregnation.

Thin Film Coating

ELCAN has over 65 years of experience in thin film coating design and production including anti-reflective coatings, mirror, hard-carbon coatings, beam splitters, ITO coatings, polarizers, dichroic filters and band pass filters.

We have pioneered many performance improvements in modern optics based on advances in thin film coating formulations for applications ranging from ultraviolet to infrared wavelengths.


ELCAN assembles products ranging from simple lens assemblies to complex EO/IR systems in varying quantities from a single prototype to full-scale mass production.

In order to limit performance degradation due to contaminants and improve cost-effectiveness of mission results, Raytheon ELCAN has established Class 100-10,000 clean rooms for precision assembly.

For high-volume production and automated assembly, alignment and test benches are established. Raytheon ELCAN undertakes applied R&D projects to enhance production yields, advance product performance, provide improved customer value and develop new technologies and capabilities to meet and exceed customer mission requirements.


Our facilities include a variety of electronic autocollimators and focusing telescopes, Modulation Transfer Function test benches and interferometers with computerized data storage and analysis. This is critical to achieve extremely precise tolerances such as those on shared aperture systems used as target and flight control for UAVs.
