Ultra Broadband Wire Grid Polarizers consist of a thin layer of aluminum MicroWires™ layered between two Fused Silica windows. Designed for multi-wavelength applications, these polarizers have excellent heat resistance and performance beginning in the UV and extending into the infrared (IR). Note: The input beam should be oriented towards the cover glass side, indicated by a reference mark. When the reference mark is located in the upper left side of the polarizer, the transmission axis will be oriented from left to right.
Wire Grid Polarizers are constructed by attaching MicroWires™ to the first window, and then applying a thin cover glass onto the wire grid surface to protect the wire from damage. The light is polarized by the birefringent nature of the wire grid surface. When incident light strikes the wire grid, P-polarized light contacts a dielectric and is transmitted, while
S-polarized light contacts a mirror and is reflected.
