High contrast Infrared Polarizer P02
Free-standing grid array polarizer for the far-infrared and mid-infrared. Patented design extends high-frequency limit by one order of magnitude to typically 2500cm-1 or 4µm. A polarization contrast better than Tp/Ts = 10,000 : 1 is reached.
The CA 25mm polarizer is mounted in a 34.8mm dia. x 8mm thick metal ring.
