75mm focal length Thermal Imaging Lens
This high‑performance 75mm thermal imaging lens is independently developed and manufactured by BOSHI Optical Technology. This thermal imaging lens is optimised to pair with 640×512 thermal 17μm infrared detectors to realise high‑definition long‑wave infrared imaging output. It adopts large aperture F1.0 design. This optical athermalization lens delivers steady optical athermalization effect without additional electric focusing assemblies and maintains consistent imaging quality across extreme working temperature ranging from 40 degrees below zero up to 80 degrees centigrade. Equipped with high‑definition exposed‑optics coating, the lens achieves transmittance as high as 88 percent and relative illumination above 96 percent to realise even brightness distribution for full field of view. Its distortion value is controlled at 0.85 percent to reduce geometric deviation of captured images. It applies M34 mounting standard to support fast and stable assembly work. Front‑element IP67 rating offers outstanding dust‑proof and moisture‑proof performance. With net weight around 475 grams, this compact IR lens supports seamless integration for multiple infrared observation devices. Strict production quality control implemented by BOSHI Optical Technology makes this long wave infrared objective a reliable optical core component for outdoor thermal observation and monitoring work.
