Description

A calibration tool for measuring the absorptivity of optical components

technical field

The utility model relates to the technical field of optical element measurement and calibration tooling, in particular to a calibration tool for measuring the absorptivity of optical elements.

Background technique

When the optical component testing equipment performs the absorbance test, it needs to have a reference value first. This reference value requires the equipment to calibrate the calibration sample with known absorbance value first, and store the calibration value as the reference value for detection. When measuring other samples, compare the measured value with the reference value to convert the absorbance of the test sample.

Generally, during calibration, the calibration sample and the test sample share the same clamping position, and the sample needs to be replaced during calibration. If the size of the test sample and the calibration sample are different, it is necessary to adjust or replace the fixture before clamping. After the calibration is completed, the calibration sample needs to be removed and stored with the device. The operation flow of the whole calibration process is complicated and the efficiency is low.
