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.
