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.

13mm F1.0 M22 12um HD Lens Long-wave Infrared Thermal Imaging Lens is a 13mm F1.0 LWIR thermal lens working at 8–12μm, optimized for 640×512 (12μm pitch) uncooled infrared detectors. Core Strengths: 1.Ultra-large F1.0 aperture + ≥86% high transmittance AR coating greatly boosts weak heat source detection sensitivity; 2.Excellent imaging uniformity (≥75% relative illumination) and low distortion (≤-1.5%) ensure accurate thermal measurement without edge darkening or geometric deviation; 3.Front lens IP67 waterproof/dustproof rating and -40℃~+80℃ wide temperature range support all-weather outdoor deployment without extra protective housings; 3.1m to infinity continuous focus covers both close-range equipment inspection and long-distance surveillance; standard M20×0.5 mount ensures broad compatibility with mainstream infrared camera cores. Main Applications: Power grid inspection, perimeter & border security, industrial predictive maintenance, rail/vehicle thermal monitoring, forest fire prevention, and emergency search & rescue. Competitive Edge: Outperforms conventional F1.4/F1.8 13mm IR lenses with superior light throughput, native IP67 protection, precise measurement performance and extreme environment adaptability.
