Detector for self correcting type transparent material refractive index

Abstract

This invention relates to a self-aligned transparent material refractive rate test instrument, which has a flat base fixed with a laterally placed test drawtube on it by a locating supporting piece, a working piece locating base is set at the front of its exit light and a camera device is set at the tail t obe connected with a computer by a transmission interface, a shaft position coder is set on the top of the drawtube and a transmission interface connected with the computer is set on the coder to be connected to a minimeter on the drawtube by a stem having an adjusting handwheel and a monochromatic lamp.

Description

technical field

[0001] The invention belongs to the technical field of optical testing instruments, and is a self-aligning transparent material refractive index detector suitable for optical glass. Background technique

[0002] In optical design, in order to make the optical parts meet certain optical path requirements, according to the design requirements, the refractive index of the optical parts must be limited to a certain range. As a result, the parts meeting the design requirements were selected. In the existing technology, a V-prism refractometer is usually used to detect the refractive index of optical glass and transparent materials. The refractive index of the material to be measured can be obtained from the deflection angle. The instrument adopts a structure that separates the collimating light path from the receiving light path, including a sighting lens barrel and a numerical reading lens barrel. When testing the deflection angle, aiming and reading must be ca...
