Key Features
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.Surface Quality: 80 – 50 scratch-dig
Beam Deviation: ≤ 1 arc-min
Contrast Ratio (see graphs in tabs below)
Typical Reflection > 80:1
Typical Transmission > 2000:1
Maximum Temperature: 200 ˚C for single layer
Laser Damage Threshold: 10 kW/cm², CW at 1540 nm
