Product Description

Optical AR Coated N-BK7 Liquid Crystal Polymer Depolarizers for Laser 

Liquid Crystal Polymer Depolarizers

Liquid Crystal Polymer (LCP) Depolarizers (US Patent 9,599,834 B2) are patterned microretarder arrays designed to convert a linearly polarized beam of light into a pseudo-randomly polarized beam. 

• Optic Axis Alignment Not Required
• Ideal for Both Broadband Light Sources and Monochromatic Beams
• Depolarize Beams with Diameters as small as 0.5 mm
• Three AR Coatings Available
  • 350 - 700 nm
  • 650 - 1050 nm
  • 1050 - 1700 nm
• Relatively Insensitive to Angle of Incidence (see LCP vs. Quartz Tab for Details)
