Product Description & Test Report
Crafted with a premium ZWB3 optical glass lens, the ZWB3 UV-transmitting black glass boasts excellent ultraviolet (UV) transmission performance. It supports a wide range of UV wavelength bands, including 255nm, 275nm, 295nm, 310nm, 320nm, 340nm, 365nm, and beyond. The lens effectively filters out 99% of stray and unwanted visible light, delivering pure, stray-light-free UV output that enhances fluorescence contrast and ensures clearer detection results. Superior to ordinary resin or glass lenses, this professional UV black glass offers exceptional UV transmittance, excellent high-temperature resistance, scratch resistance, and a long service life—remaining free from aging and yellowing even after long-term use. Widely applicable to UV analyzers, gel imaging analysis systems, and professional UV flashlight lenses, the attached spectral curve presents the standard spectrum of the ZWB3 black UV filter glass, with the black line denoting its spectral characteristics.
