Wire Grid Polarizing Beam Splitter

KEY FEATURES
  • Broadband wavelength range, 420-2600 nm
  • Wide acceptance angle
  • Custom sizes and shapes
  • Excellent transmitted contrast
DESCRIPTION

Meadowlark Optics presents its Versalight wire grid polarizing beam splitters. Manufactured for wavelength ranges between 420 and 2600 nm, this polarizer is ideal for broadband and wide field-of-view applications.

Wire grid polarizing beam splitters are manufactured out of our Versalight wire grid polarizer sandwiched between right angle prisms. No AR coatings are standard for maximum wavelength usage. Broadband AR coatings are available on the faces of the cube covering either visible (450 to 1100 nm) or IR (1000 to 2400 nm.)

Please contact your Meadowlark Optics Sales Engineer for assistance with your custom needs.
