MWIR Polarizer
KEY FEATURES
- Excellent contrast ratio
- Thin profile
- High transmission
- Custom apertures > 2 inches available
DESCRIPTION
This polarizer is a wire grid on an antireflection coated silicon substrate optimized for 3 to 6 microns. The ring mounting provides for ease of handling and has the polarization transmission direction marked. The wire grid surface is quite delicate and should only be cleaned non-mechanically. Standard outer diameters are one and two inch but custom sizes, shapes and unmounted polarizers are also available.
