This high‑performance thermal imaging lens is developed and manufactured by ShangHai SILK Optical Technology CO., LTD, tailored for uncooled long‑wave infrared thermal imaging devices. Featuring 50mm focal length and bright F1.0 large aperture, this infrared lens delivers outstanding light-gathering capability for low‑light thermal detection scenarios. It matches 640×512,12μm infrared detectors, working within classic 8‑12μm long‑wave infrared spectral band.

This high-performance thermal imaging lens is developed and manufactured by ShangHai SILK Optical Technology CO., LTD. As a premium long-wave infrared lens with 9.1mm focal length and ultra-large F1.0 aperture, it is engineered to match uncooled 640×512detector, 12μm infrared detectors. The lens adopts HD exposed optics coating and delivers high transmittance over the 8–12μm working waveband.Featuring a compact M17×0.5 mount structure and IP67 front element waterproof rating, this thermal imaging lens supports focusing from 3 meters to infinity. It achieves high relative illumination above 84% and controlled distortion, maintaining stable optical performance between -40°C and +80°C. Designed for all-weather field deployment, this long-wave infrared lens balances wide field of view and clear thermal imaging. It serves as an ideal optical core for portable and compact thermal camera equipment across industrial monitoring, security and inspection scenarios.
