Design of Refractive Index Test Equipment of High Refractive Index Glass Beads by Secondary Rainbow Method

Abstract:

This paper explains the theory of the secondary rainbow and provides a test method of refractive index of the high refractive index glass beads. We carry out the optical design relate to the method, and design a refractive index test equipment. Additionally, we analyze the calibration requirements of the equipment and discuss the cause of error and measurement accuracy. The designed equipment can achieve a continuous, accurate, statistical measurement.
