Standard Practices for Verification and Calibration of Polarimeters

2020

3

ASTM Vol.15.02 (2022)

This practice covers the standards for the verification and calibration of polarimeters required to maintain these instruments and ensure that the optical setup is within specification for satisfactory measurements. Verification and calibration procedures are performed using two types of procedures: Procedure A (verification) and Procedure B (calibration). Procedure A is done by measuring individual components and their orientation to ensure that they comply accordingly. Procedure B is done by determining the accuracy of the polarimeter using a calibrated gage or retarder.
