The specification for the first time to develop. Polarizing calibration specification

1 Scope

This standard applies to the use of polarized light measuring various types of polarizing material phase delay of the calibration. 2. References GB/T 26827-2011 wave plate phase delay calibration method of measuring apparatus For dated references, only the dated edition applies to this specification; undated reference documents Member, the latest edition (including any amendments) applies to this specification.

3 Terms

3.1 phase delay phaseretardation When a bunch of polarized light beam is incident to the wave plates, broken down into the wave propagation along the original film direction but the direction of vibration perpendicular to each other Of o light and e light, due to the different propagation speed retardation caused. 3.2 polariscope polarimeter Instrument for measuring the phase delay, also known as phase delay measuring instrument, polarizing strain gauge.

4 Overview

Instrument is measuring the polarization of transparent plastic, glass and other transparent materials to light birefringence, and the phase delay Belated quantitative characterization instruments. Polarization analyzer consists of a light source, a polarizer, the sample compartment, an analyzer, a photodetector and a letter No part of the treatment. Figure 1 is a schematic diagram of a polarization analyzer. Figure 1 Schematic polarization analyzer Figure 1 polarizer, sample, the analyzer should be placed parallel to each other and perpendicular to the optical path. Polarizer, a sample analyzer Possessing at least one device can be rotated about the optical axis. Delay stage times with measuring equipment, the system should have a light source Two optical radiation can be used to measure the actual output and more different wavelengths. Measured by light line with the actual application requirements, commonly used wavelength of 532nm, 540nm, 546nm, 560nm, 565nm, 589nm, 632nm and the like.

5 Metrological characteristics

5.1 light spectrum half width
