Polymer Circular Polarizer RCP25-532-CRM

Polymer Circular Polarizer — Model RCP25-532-CRM

Polymer Waveplate/Thin Film Linear Polarizer, operating wavelength 532 nm, clear aperture Ø20 mm, ellipticity angle ≥43.5°.

Overview

Polymer circular polarizers convert light of any polarization state within the working wavelength into left-handed or right-handed circularly polarized light, and can also convert left-handed or right-handed circularly polarized light into linearly polarized light. Compared with economical thin-film circular polarizers, polymer circular polarizers achieve higher ellipticity requirements (≥43.5°). This model is mounted in a rotation mount, with the transmission axis of the linear polarizing film aligned with the 0° marking. When the beam is incident from the side with the marking, the output light is circularly polarized; when incident from the opposite direction, the output is linearly polarized.
