Product Family Description

  • Highly Durable Polymer Sheets
  • λ/4 (WP140HE) Achromatic Retarder with Greater than 90% Transmission from 450-700nm
  • λ/4 (WP140HE), λ/2 (WP280), and 1λ (WP560) Retarder Films Available

Polymer Retarder Film is an extremely durable, birefringent polymer sheet that has been designed to modify the polarization state of transmitted light. The highly transparent, achromatic λ/4 (WP140HE) and λ/2 (WP280) Polymer Retarder Films consist of a single layer, modified polycarbonate sheet that acts an achromatic retarder, and is optically and mechanically sound up to 90°C or 80°C respectively. The 1λ (WP560) Polymer Retarder Film consists of two λ/2 films that have been laminated together to create retardation values of 560nm. These films are ideal for use in a variety of coherent and polarized light applications, including circular polarizers, LCDs, and fiber optics.

Note: Custom Options are available on request. More about our polarizer and retarder capabilities can be found here.
