Custom Ge Lenses for MWIR and LWIR Systems

Germanium optics for infrared assemblies

Germanium is widely used for MWIR and LWIR optical systems because of its infrared transmission and machinability for precision lenses and windows. Junbang reviews each Ge lens project against wavelength range, lens geometry, centering, surface figure, surface quality, coating and inspection requirements.

Typical work includes plano-convex, plano-concave, meniscus, spherical and custom germanium lens geometries for OEM infrared modules.

Typical applications

• Thermal imaging lenses and modules
• Infrared sensing and monitoring systems
• MWIR and LWIR optical instruments
• Prototype and replacement IR optical components

RFQ information we recommend sending

Please include drawing, material grade, diameter, center thickness, clear aperture, radius data, coating band, quantity, surface figure, surface quality, centering, environmental requirements and inspection report needs.
