SWIR Imaging
Lens systems for InGaAs cameras, machine vision, semiconductor inspection, moisture analysis and low-light imaging.
SWIR • MWIR • LWIR
Custom Infrared Imaging Lenses
Custom infrared imaging lenses and precision IR optical components engineered around detector format, spectral band, field of view, operating environment and mechanical envelope.
INFRARED OPTICAL ENGINEERING
Engineered Across SWIR, MWIR and LWIR
COE Sapphire provides custom infrared imaging lenses and precision IR components for thermal imaging, sensing, gas detection, industrial inspection and defense systems. We support projects from individual infrared elements to complete lens assemblies.
MWIR Imaging
Precision optics for cooled thermal cameras, gas detection, high-temperature monitoring and long-range observation.
LWIR Thermal Imaging
Germanium and other IR material lens systems for uncooled cameras and 8–14 μm thermal imaging.
MATERIALS & COATINGS
Material Selection Matched to the Infrared Band
Infrared performance depends on more than lens geometry. Material transmission, thermal behavior, coating design, surface quality and mechanical integration must work together.
Infrared Materials
Germanium, silicon, zinc selenide, zinc sulfide, sapphire and other infrared materials are evaluated according to wavelength, environment and manufacturability.
Band-Specific Coatings
AR, broadband AR, protective and DLC coating options can be coordinated around the material, angle of incidence and operating environment.
Design for Manufacturing
Optical and mechanical tolerances are reviewed together to protect system performance without unnecessary manufacturing cost.
FROM CONCEPT TO PRODUCTION
Design, Manufacturing, Assembly and Inspection
Support may include optical and opto-mechanical design review, material sourcing, precision machining, grinding and polishing, diamond turning where appropriate, thin-film coating, centering, assembly and final inspection. Prototype builds can transition into repeatable production after design verification and tolerance review.
Design Inputs
Wavelength band, detector format, pixel pitch, focal length, F-number, field of view, distortion, operating temperature and housing constraints.
Controlled Manufacturing
Spherical and aspheric elements, windows, protective windows and complete lens assemblies manufactured to drawing requirements.
Quality Verification
Dimensional inspection, surface quality, centration, interferometry, spectral transmission and assembly-level optical testing as required.
IN-HOUSE VERIFICATION
Coating, MTF and Interferometric Inspection
Manufacturing and inspection planning are coordinated with the optical design and application requirements.
Optical Coating
Band-specific coating support for infrared materials and finished optical components.
MTF Testing
Assembly-level image performance verification can be defined according to the lens requirement.
Interferometric Metrology
Precision optical surfaces can be evaluated with interferometric measurement where applicable.
