Key Features
- Broadband use
- Reflective polarizer
- Large acceptance angle
VersaLight™ is constructed of a thin layer of aluminum MicroWires® on a glass substrate and sets a new standard for applications requiring high durability, contrast and a wide field of view for visible through infrared wavelengths. VersaLight offers the performance quality of dichroic sheet polarizers while extending the operating temperature to 200 °C.
The nature of VersaLight’s™ MicroWire® construction allows it to perform as an exceptional polarizing beam splitter. In operation, VersaLight reflects one polarization state and transmits another, both with high contrast. VersaLight offers the broadest band and highest field of view of any polarizer material presently available. VersaLight can be shaped as needed and stacked to achieve very high contrast ratios. Large aperture VersaLight Polarizers are available on a custom basis, up to 200-mm rounds.Common Specifications
