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.

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.
