UV-Vis-NIR Polarizers

UV-Vis-NIR Polarizers

REFLEX Analytical introduces and complements their infrared polarizers with a UV-Vis-NIR polarizer series. You may refer to this Product DataSheet to assist with previewing features, performance curves and ordering the items below. Notice the UV polarizer contrast ratio is greater than 10,000:1 making these high-performance polarizers a competitive alternative to calcite polarizers. Additionally, the large 20° acceptance angle of the UV-Vis-NIR polarizers eases alignment concerns during use compared to a traditional calcite polarizer.

The manual automated polarizers are mounted in a standard 2" x 3" slide mount and are compatible with all FTIR spectrometers and breadboard benches. The automated polarizers specifications are identical to the manual series with the exception of computer control utilizing software and motion control; permitting programmable and sequential selection of polarization angles along with the automatic collection of spectra. An additional benefit of the automated polarizer is the reproducibility and setting of polarization angles; increasing accuracy to +/- 0.50°. The speed of auto-rotation is equally impressive; rotating from 0 to 90° in approximately 2 seconds.
