JJF1497-2014《偏光仪校准规范》于2014年11月17日由国家质检总局批准发布并于2015年2月17日起实施,旨在保证偏光仪测量量值的准确传递及统一,使不同仪器之间的校准数据具有可比性。一、规范的主要内容1.背景偏光仪测量的物理量称之为相位延迟,并非广泛使用的亮度、透射比等较为直观的光学类物理量。从定义上讲,“当一束偏振光束入射到波片时,在 JJF1497-2014 Polarizer Calibration Specification was released on 17 November 2014 by AQSIQ and implemented on February 17, 2015. The purpose of this specification is to ensure the accurate transmission and unification of the measured values ​​of the polarimeter. Calibration data between instruments is comparable. First, the normative main content 1. Background Polarimeter measuring the physical quantity called phase delay, not widely used brightness, transmittance and other more intuitive optical physics. By definition, ”when a beam of polarized light is incident on a wave plate,
