OWL Polarizer - Outrageously Wide Lambda

Meadowlark Optics provides an extremely broadband polarizer solution - OWL (Outrageously Wide Lambda) Polarizer. Manufactured for a wavelength range of 300 to 2700 nm rivaling the span of a Glan-Thompson calcite polarizer, this optic is ideal for broadband applications.
The proprietary composition of the OWL 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 thickness of only 0.182” including mount and solid contrast ratio through the entire range from UV to IR.


  • Extremely boradband
  • Wide acceptance angle
  • Custom sizes and shapes
  • Excellent transmitted contrast
  • Thin, compact design
