black glass for ultraviolet transmission
ZWB1、ZWB2、ZWB3
Through
ultraviolet black glass has a good UV penetration, which at long wave, short
wave their models were ZWB1, ZWB2, ZWB3 (254nm \ 310nm \ 365nm), can filter out
(absorb) visible light. Mainly used for geological surveying, nondestructive
testing, medical analytical instruments, UV light source filter.
