Product Description

Due to the wire grid being exposed, special care should be taken when handling to prevent damage to the polarizer.

Product Family Description

  • AR Coated for Superior Transmission
  • High Heat Resistance with Low Thermal Expansion
  • Feature Wide Angle of Incidence Range without Performance Loss

High Contrast IR Wire Grid Polarizers are ideal for broadband infrared applications that require high transmission and contrast, including spectroscopy, thermal imaging, or astronomy. High Contrast IR Wire Grid Polarizers are designed using a lightweight, thin, silicon substrate, making them ideal for weight-sensitive systems, such as UAVs. The polarizers’ wire grid technology allows the angle of incidence to vary ±20° without displaying performance loss.

Note: Due to the wire grid being exposed, special care should be taken when handling to prevent damage to the polarizer.
