This article presents a three autocollimation method (TAM) for measuring the refractive index (RI) of optical glass. The popular minimum deviation method (MDM) for RI measurement is accurate, but it is very laborious, since the procedure of determining the minimum possible angle requires many iterations. TAM allows the calculation of RI based on the measurement ...
