4.1mm F1.0 M22 12um Lens Long-wave Infrared Thermal Imaging Lens is high-performance, rugged, and highly compact infrared lens engineered for premium commercial and industrial applications. Striking an exceptional balance between physical size, weight, and premium optical performance (large aperture, wide FOV), it stands out as a premier choice for drones, automotive night vision, and harsh-environment security applications.

Standard M12 F2.4 2.8mm 1/2.7" Security CCTV Lens, and all products have been tested by MTF instruments, resulting in higher consistency compared to products from other suppliers. You can rest assured to purchase standard M12 lenses from our factory.

This high‑performance 75mm focal length 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.

M12 2.85mm 1/2.9" F2.3 Security Lens PL071, and all products have been tested by MTF instruments, resulting in higher consistency compared to products from other suppliers. You can rest assured to purchase standard M12 lenses from our factory.

This compact M12 wide angle lens is professionally engineered for 1/3” image sensors, delivering ultra-wide diagonal 140° field of view for comprehensive scene capture. Manufactured by ShangHai SLIK Optical Technology CO., LTD, this fixed focal CCTV lens adopts mature optical layout to balance wide coverage and controllable TV distortion, making it a reliable IR corrected board lens for mass-market surveillance cameras. With F2.5 large aperture design, this low light camera lens supports clear imaging under dim indoor environments, while its 55.0% relative illumination effectively suppresses corner vignetting. Its CRA less than 22.8° guarantees excellent compatibility with mainstream CMOS sensors. The compact TTL 15.0mm structure simplifies camera module assembly. As a versatile industrial vision lens and security board lens, this wide FOV optical lens fits miniature IP cameras, home monitoring devices and embedded vision hardware. ShangHai SILK Optical Technology CO., LTD strictly controls optical tolerance to ensure consistent performance of every compact board camera lens for global buyers.

Injection molding of capsule shell, has a high transmittance optical effect, small size, light weight, and is made of corrosion-resistant polymer material, which does not rupture.
