This file introduces the polarizer and depolarizer for the Agilent Cary series UV-Vis-NIR spectrophotometer.
This document describes the use of polarizers and depolarizers as optical accessories for Agilent Cary Series UV-Vis-NIR spectrophotometers. It explains that while baseline measurements often normalize system dependencies, specific sample analyses require active control of the light's polarization state to prevent artifacts like ordinate steps or measurement errors caused by anisotropic samples.
| Wavelength range | 250-3000 nm |
|---|---|
| Angular polarized field | 8.5° |
| Length to aperture ratio | 0.85 —1.0 |
To control the plane of polarization, the Glan-Taylor polarizer should be placed between the monochromator and the sample.
No, transmission measurements using an integrating sphere detector do not require a depolarizer after the sample because the sphere removes polarization before the beam reaches the detector.
