Abstract
Description
Technical Field
[0001] The invention relates to the technical field of optical element measurement and calibration tooling, in particular to a calibration tooling for measuring the absorption rate of an optical element. Background Art
[0002] When the optical component detection equipment performs absorbance detection, it must first have a reference value. This reference value requires the equipment to calibrate the calibration sample with a known absorbance value, and store the calibration value as the reference value for detection. When measuring other samples, the measured value is compared with the reference value to convert the absorbance of the test sample.
[0003] Generally, during calibration, the calibration sample and the test sample share a clamping position. During calibration, the sample needs to be replaced. If the size of the test sample and the calibration sample is different, the fixture needs to be adjusted or replaced to clamp the calibration sample. After calibration, the calibration sample needs to be removed and stored in the device. The entire calibration process is complicated and inefficient. Summary of the invention
