Title: Design of High Accurate Determination Instrument of Optical Glass Refractive Index
Abstract: The whole design of high accurate determination instrument of optical glass refractive index was analyzed,paraboloid reflector was used in the collimator and self-collimation telescope.Plane shafting was adopted in the precision turntable.The precision of 24 bit increment coder was 0.52.Data of PSD sensor and coder were collected with SCM as on the stage and computer as background.The least deflection angle method and three least deflection angle method were used in the high accurate determination of optical glass refractive index,and the measuring precision reached to 10-6.
