Abstract

Disclosed is an optical glass filter causing no unstabilization of transmission and having flat spectral transmission characteristics with a high degree of precision. The optical glass filter is based on a silicate-based glass composition, essentially includes at least NiO, MnO2 and Co2O3, and has flat spectral transmission characteristics in a wavelength range of 450-650 nm.
