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 2000 nm.) Custom AR coatings are available upon request. Please contact one of our Meadowlark Optics Solutions Engineers for more information.
