Ultraviolet glass
Ultraviolet glass has ultraviolet black glass and white glass. Ultraviolet glass has good ultraviolet. It has short wave and long wave which are (ZWB1,ZWB2,ZWB3 254nm/310nm/365nm) .Ultraviolet white glass is a kind of colorless cut-off glass which wavelength is from 220nm to 380nm.The transmission is over or equal to 89.5%. At the same time, it can filter absorption visible light. Mainly apply in geology survey, NDT inspection, medical analysis instrument, ultraviolet light filter.
