DETAILS
ZWB1 ZWB2 ZWB3 UV Selective Absorption Optical Glass Filter
ZWB1/ZWB2/ZWB3 UV Selective Absorption Optical Glass Filters Designed for precise UV spectrum extraction, ZWB series filters transmit key mercury lamp wavelengths (254nm, 313nm, 365nm) while blocking visible light. ZWB1 (equivalent to Schott UG11/Hoya U-340), ZWB2 (UG1/U-360), ZWB3 (UG5/U-330), customizable thickness (1-5mm), widely used in UV transilluminators, geological surveys, medical diagnostics, and industrial NDT. Features high chemical stability, ISO-certified quality, and supports laser engraving/size customization.
