Angle detection device and detection method for optical crystal

Abstract

The invention discloses an angle detection device and an angle detection method for an optical crystal. The angle detection device comprises a positioning tool, a target disc and a light source, wherein the positioning tool is used for fixing a to-be-detected optical crystal; the target disc and the positioning tool are arranged at intervals, a plurality of marking rings are arranged on the surface, facing the reflecting surface of the to-be-detected optical crystal, of the target disc; the marking rings are concentrically arranged; and the light source is arranged between the positioning tooland the target disc and is used for emitting light to the reflecting surface of the to-be-detected optical crystal. According to the angle detection device and the angle detection method for the optical crystal, the structure is simple, the measured angle value is directly read and does not need to be obtained through calculation, the detection efficiency is improved, and the angle detection device is suitable for batch detection.

Description

technical field [0001] The invention relates to the field of optical equipment, in particular to an angle inspection device and a detection method for optical crystals. Background technique [0002] A large number of optical crystals need to be used in optical fiber communication, such as: fiber optic adapter ferrule, collimator glass capillary, FA products, optical isolator, etc. Optical crystals will be set at a certain angle to light when they are in use. Take optical isolators as an example: semiconductor lasers and optical amplifiers are very sensitive to reflected light from connectors, splicing points, filters, etc., and cause performance degradation; therefore Optical isolators are required to block reflected light. An optical isolator is an optical passive device that only allows light to pass in one direction and blocks light in the opposite direction. The light reflected by the fiber optic echo can be well isolated by the optical isolator. Optical isolators are...

Problems solved by technology

[0004] In order to detect the angle, the current solution is generally to measure the high and low XYZ coordinate axis positions of multiple points on the angle surface, and calculate the angle through the trigonometric function formula that comes with the software, such as Nikon's image measuring instrument. The equipment price of this solution is relatively high, and the measurement It takes a long time (about 30s / pcs), and it is not suitable for mass production solutions
