A photometer to measure light scattering in optical glass

P.J.R.Laybourn, J.P.Dakin, W.A.Gambling

Abstract

A photometer is described for the measurement of light-scattering in high-quality, optical bulk glass. The photometer operates continuously over the wavelength range 0.5 to 1 μm and can measure scattering coefficients down to a level of 5 x 10−7 cm−1. A photon counting technique is used for light measurement and calibration is by reflection of the incident beam from on ideal diffusing screen. Measurements with high-purity benzene are in good agreement with computed and previous experimental values. Results of scattering from two samples of optical glass are given.
