China 13mm Manufacturers, Suppliers, Factory

Developed by BOSHI Optical Technology, the PL‑1645F‑M12 is a compact fixed‑focus cone lens built around 16mm focal length and F4.5 specifications to serve 1/2" sensor imaging hardware. This M12 mount optical assembly adopts full‑glass four‑element structure, delivering 28.3°FOV alongside 8.5mm image circle to match 1/2" sensor and smaller image sensors for space‑limited board‑level camera optics systems. It reaches 95 percent high relative illumination and realizes low distortion performance with TV distortion value of ‑0.25 percent. Its mechanical back focal length measures 3.65 mm and overall total track length hits 28.65 mm for easy embedding into compact camera modules. Created for machine vision and other embedded imaging scenarios from industrial inspection to biometric identification, the lens from BOSHI Optical Technology tightly controls chief ray angle under 8 degrees to restrain vignetting and color shift when cooperating with mainstream CMOS sensors. It balances resolution, miniaturized dimension and cost efficiency, and fits factory automation, logistics barcode reading and medical imaging devices for stable and authentic image output.

Manufactured by BOSHI Optical Technology, this 13mm F1.0 Uncooled Thermal Lens is optimized for the 8‑12μm long‑wave infrared band. This Thermal Imaging Lens is perfectly matched with 640×512 resolution detectors with 12μm Pixel dimension. Adopting F1.0 large aperture, the lens captures faint infrared radiation to deliver clear thermal outputs under low‑contrast scenes. Its front optical element reaches IP67 protection grade, and exposed surfaces are covered with durable AR coating to sustain stable performance in complicated outdoor surroundings. The focus covers 1 meter to infinity, and the working temperature spans from ‑40℃ to +80℃. The compact M20×0.5 Mount supports convenient assembly. BOSHI Optical Technology carries out strict optical calibration to guarantee stable and consistent optical quality for mass integration of thermal imaging devices.

This high‑performance 75mm thermal imaging lens is developed and manufactured by ShangHai SILK Optical Technology CO., LTD, optimized for 640×512, 17μm infrared detectors to deliver sharp long‑wave infrared imaging output. Featuring a large aperture F1.0 design, this F1.0 athermal lens realizes reliable optical athermalization without extra electric focusing parts, maintaining stable imaging quality within‑40℃ ~ +80℃ extreme working environment. With HD exposed‑optics coating, high transmittance up to 88% and over 96% relative illumination, this infrared lens restores uniform brightness across the whole field of view, while low 0.85% distortion minimizes image geometric deviation. The M34×0.75 mechanical mount ensures quick and stable assembly, and IP67 front‑element waterproof rating brings solid dust‑proof and moisture‑proof capability. Weighs only approx.475g, the compact‑structured thermal imaging lens suits integration into various infrared observation devices.
