● Aspherical and binary optical technology adoped in design
● Various types of IR materials are used
The double field of view (or double FOV)lenses and continuous zoom lenses used in long wavelength infrared range (LWIR) uncooled thermal imaging cameras are offered, the lenses are designed for a variety of uncooled FPA detectors. Some designed modules are listed and the custom modules are available upon customer’s request.
Modules or Types
Designed for uncooled LWIR FPA detectors:
384 x 288 – 25um; 640 x 480 – 17um; 320 x 240 – 25um; 320 x 240 –17um and 160 x 120 – 25um
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.
- Multiple field and infrared zoom optical system Double field of view, three visuals field as well as infrared zoom optical system achieve different FOV to observe the target, greatly improves the performance of the lenses.
- Advanced equipment and machines are used to process the infrared materials optics: ultraprecision 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) ; 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.
