Introduction

This station mainly trains and learns to detect the splitting ratio of spectroscopic elements, the extinction ratio of polarizing elements and the diffraction efficiency of diffractive optical elements, so that students can understand the detection standards and methods of polarizing elements and diffractive elements.

Training Content

Extinction ratio detection of polarizers;

Polarization beam splitter prism extinction ratio detection;

Spectral ratio detection of dichroic prism/flat film;

Diffractive optical element diffraction efficiency detection.
