Variable Circular Polarizers VCPBS24-780

Variable Circular Polarizers — Model VCPBS24-780

Laser line variable circular polarizer, Quartz + Liquid Crystal Polymer / N-BK7 window sheet, 10.0 mm clear aperture, operating wavelength 780 nm, extinction ratio 2000:1 (Beamsplitter cube).

Overview

LBTEK combines a polymer true zero-order quarter-wave plate installed in an RM05 rotation mount with a laser line polarizing beamsplitter cube installed in a 30 mm coaxial beamsplitter cube mount to form a laser line variable circular polarizer. The line engraved on the top indicates the optical path direction, with the fast axis of the wave plate aligned to the 0° marking line. The initial position is preset and locked, resulting in right-handed circularly polarized emergent light (observed as left-handed circularly polarized light when facing the beam). The included wrench allows for loosening and rotating the quarter-wave plate to achieve various emergent lights, including elliptically, circularly, and linearly polarized light.
