The IR lenses are designed for 640×480-25μm FPA detectors used in long wavelength infrared range (LWIR) uncooled thermal imaging cameras, with manual or motorized mechanism and in wide range of focal length, the single FOV, double FOV and continuous zoom lenses are available. The listed designed modules are ready for your selection and the customs modules are available upon customer’s request

Features
 Aspheric Technology and Binary Optics Technology are used in design, which effectively reduce the spherical aberration, distortion and other various aberrations, achieve athermalization design and reduce the number of needed lens elements, lower the cost.
 Various type of the infrared materials (like Ge, ZnSe, ZnS,AMTIR ect.) are used in the lenses, which would successfully eliminate the aberration of the image and improve the quality of imaging, especially for the large diameter telephoto lenses.
 Advanced equipment and machines are used to process the infrared materials optics: ultra-precision single point diamond processing machine to achieve the precision aspheric in 3nm, diffractive surface processing equipment to process the Ge, ZnSe, ZnS and AMTIR materials.
 Different types of coating are made on the lens optics: high-efficiency anti-reflection coating (or high-efficiency AR), durable anti-reflection coating (or Durable AR) and diamond-like hard carbon coating (or DLC coating).
 Complete quality assurance system Within our quality system, we works out a series of specific craftworks and develops a strict test procedure to guarrantee the quality of products.
