Key Features
Meadowlark Optics now offers an extremely broadband polarizer solution with up to 1,000,000:1 contrast ratio. Our new Ultra Broadband Polarizer performs well over a wavelength range of 300 to 2700 nm, rivaling the span of a Glan-Thompson calcite polarizer in a thin, compact design.
The proprietary composition of the Ultra Broadband Polarizer allows for an unprecedented width of spectral range at a fraction of the cost of other competing polarizers. This cost savings is coupled with a mount thickness of only 0.182” and high contrast over the entire range from UV to MWIR. Its wide acceptance angle, remarkably larger possible clear aperture, and compact, light-weight design allow for versatility in complex or space-limited optical setups.
