ULTRAVIOLET PERMEATION VISIBLE LIGHT ABSORPTION GLASS AND ULTRAVIOLET PERMEATION VISIBLE LIGHT ABSORPTION FILTER

摘要

PROBLEM TO BE SOLVED: To provide an ultraviolet permeation visible light absorption glass selectively high in permeability in a wavelength region of 350 to 370 nm while reducing environmental load and having suppressed deterioration due to a solarization.SOLUTION: There is provided an ultraviolet permeation visible light absorption glass containing practically no Pb, As, Cd and Cr and CoO of 0.1 to 2 mass%, NiO of 1 to 5 mass%, TiOof 0 to 1 mass%, NbOof 0.1 to 10 mass% and the TiOand the NbOof 0.1 to 10 mass% as total.SELECTED DRAWING: None
