About
Umicore’s GASIR® infrared lenses have been developed for an easy fit with a wide range of camera cores. Our catalog lenses provide a cost-effective
solution for high-resolution thermal imaging and sensing applications.
This lens may be offered with other coating variants upon request. This high performance lens is optimised for minimum weight. Material choices allow a moderate temperature range with passive optical athermalisation.
This lens is compatible with 12 μm SXGA detectors and smaller.
