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.

The PL-1645F-M12 from BOSHI Optical Technology is a compact 16mm focal length, F4.5 aperture fixed-focal lens engineered specifically for 1/2" format sensors. Designed with a 4-glass-element all-glass construction, this M12-mount lens delivers a 28.3° diagonal field of view and supports a maximum image circle of Ø8.5mm, making it an ideal match for 1/2" and smaller imagers in space-constrained vision systems. With a mechanical back focal length of 3.65mm and total track length of just 28.65mm, the PL-1645F-M12 integrates seamlessly into board-level camera modules for industrial inspection, biometric identification, and embedded imaging applications. BOSHI Optical Technology has optimized this 16mm F4.5 lens for superior edge-to-edge illumination, achieving 95% relative illumination and ultra-low TV distortion of -0.25%, ensuring faithful image reproduction even in high-contrast scenes. The chief ray angle is strictly controlled below 8°, minimizing vignetting and color shift when paired with modern CMOS sensors. Whether used in factory automation, logistics barcode readers, or medical imaging devices, this 1/2" sensor lens offers a balanced blend of resolution, compactness, and cost-effectiveness. Trust BOSHI Optical Technology to deliver reliable optical performance for your next-generation vision product, with the PL-1645F-M12 setting the benchmark for precision in the M12 lens category.

BOSHI Slik Camera Polarizer Lens, UV lenses can filter out ultraviolet rays from sunlight, so they are also known as ultraviolet filters. Due to the fact that UV mirrors not only improve imaging, but also protect the lens from contamination such as dust and fingerprints. So. UV lenses are always installed in front of the lens without removing them, making them the most widely used color filters. The Camera Polarizer Lens (UV Filter), a core optical accessory manufactured and supplied by Jiangxi Boshi Intelligence Technology Co., Ltd. (BOSHI), a professional Chinese optical manufacturer with nearly 20 years of industry experience, owning standardized production bases in Jiangxi Province and Shanghai City. Available in a full range of mainstream specifications including 49mm, 52mm, 58mm, 62mm, 67mm, 72mm, 82mm and 86mm, this UV filter is the most widely used optical filter for cameras, with dual core values of imaging optimization and lens physical protection. Its primary optical function is to absorb ultraviolet rays with wavelengths below 400 nanometers and partial blue-violet light, eliminating the blue-purple color cast in images captured in foggy weather or high-altitude environments, reducing ultraviolet interference on camera CCD sensors, and effectively improving image clarity and color restoration performance. Meanwhile, it acts as a durable protective layer for camera lenses, blocking dust, fingerprints and other contaminants, and can be stably mounted on the front of the lens for long-term use. The document also specifies key usage notes: the filter should be removed during backlit or night shooting to avoid aggravated glare, and taken off when using other filters such as CPL to reduce vignetting risk and ensure optimal imaging quality. Backed by a strict ISO9001:2000 quality management system covering full production processes, the company provides wholesale and customized services, accepting OEM and ODM orders including personalized logo and packaging customization for global clients.
