UV cut-off filter glass refers to the filter glass whose cut-off wavelength is located in the ultraviolet region of the spectrum. We supply UV cut-off filter glass such as ZJB365,ZJB390,H-ZJB405. The glass can be used to produce filters and lenses with UV cut-off function.
Supply forms: strips, pressed blanks, cut blanks，optical filters , spectacle lens.
It can be customized according to customer requirements. Details please contact us.
Filter glass：Various colored glasses which can absorb or transmit the spectrum selectively.
The characteristics of cut-off filter glass:
-A clear boundary between spectral absorption and spectral transmission;
-A steep curve at the initial stage of the spectral transmission curve.
-The transmittance transits from zero to a maximum in a very narrow band.
