Product number: GASIR Infrared Lens FL 35 mm f/1.2 Athermalized Fixed focus Introduction Umicore’s GASIR® infrared lenses have been developed for an easy t with a wide range of camera cores. Our catalog lenses provide a costeffective solution for high-resolution thermal imaging and sensing applications. This passively athermalized infrared lens offers diffraction-limited performance and is suitable for use with 17 µm VGA and 25 µm qVGA+ detectors or smaller. Its low distortion makes it ideally suited for use in thermal imaging applications.
