Economy Thin Film Circular Polarizer — Model LCP25-VIS-M
Left-handed circular polarizing film / N-BK7, operating wavelength 400-700 nm, clear aperture Ø20.0 mm, key spec >99%.
Overview
LBTEK Economy Thin Film Circular Polarizers convert linearly polarized light into circularly polarized light by combining a linear polarizing film with a quarter-wave retarder, sandwiched between N-BK7 substrates. Available in left-handed (LCP) and right-handed (RCP) variants for 400-700 nm. Suitable for low-cost circular polarization applications with high ellipticity uniformity (>99%).
Key Features
- Operating Wavelength: 400-700 nm
- Clear Aperture: Ø20.0 mm
- Optical component material: Left-handed circular polarizing film / N-BK7
- Anti-reflective coating: Ravg<0.5%@ 400-700 nm, 0°AOI
- Anti-reflective coating wavelength range: 400 nm-700 nm
- Transmitted Wavefront Error (TWE) (@633 nm): λ @50%CA, 2λ @90%CA
- Surface finish (scratches/pits): 40/20
Applications
- Circular polarization filtering for imaging and inspection
- Stress birefringence analysis
- Polarization-insensitive photometry
- 3D imaging and display
- Cost-effective polarization conversion in scientific instruments
