| | | Wavelength (nm) Fig. 2-8 NIR VersaLight Wire-grid Polarizer. This coating is recommended for applications requiring higher transmission from 700 nm to 1000 nm | | |
| | | VersaLight is constructed of a thin layer of aluminum MicroWires® on a glass substrate and sets a new standard for applications requiring extremely high durability, contrast and a wide field of view from VIS through IR including the telecom wavelengths. VersaLight offers the performance quality of dichroic sheet polarizers without the problems of thermal meltdown commonly associated with this technology. 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 material currently available. VersaLight can be shaped as needed and stacked to achieve very high extinction ratios. | | |
