Polarizing Plate Beamsplitter — Circular (Laser Line) — Model PBSF-24-488-SP
Operating wavelength 488 nm; extinction ratio Tp:Ts>10000:1, 45°AOI.
Overview
Polarizing plate beamsplitter for separating the p- and s-polarization components of incident light. Optimized for 45° angle of incidence with an extinction ratio Tp:Ts > 10000:1. The rear surface carries a wedge design to suppress ghost reflections.
Key Features
- Transmits p-polarized light, reflects s-polarized light
- Dual-side narrowband polarizing splitter coating, 45° AOI extinction ratio Tp:Ts > 10000:1
- Rear-surface 30 arcmin wedge design to reduce ghosting
Applications
- Polarization analysis and conditioning in laser systems
- Interferometry and beam splitting
- Optical isolation paths and polarization filtering
