Abstract
A color industrial television camera device for use in a gamma ray environment including a lens system made of radiation resisting glass. The lens system has a spectral transmittance characteristic such that the wavelength for which the lens system has a transmittance equal to one-half of its maximum transmittance in a wavelength range from 0.4 to 0.7 .mu.m is shorter than about 0.48 .mu.m on the shorter wavelength side of the maximum transmittance wavelength in the above wavelength range, thereby enabling the achieving white balance for a color display with the aid of an electric circuit.
