25mm Dia., UV Wire Grid Linear Polarizer

Product Details High Transmission from 240 – 400nm Uniform Brightness and Contrast Ideal for UV or Deep UV Applications Visible and Infrared (IR) Wire Grid Polarizers Also Available UV Wire Grid Linear Polarizers have high transmission from 240 – 400nm, making them ideal for applications in the ultraviolet (UV) or deep UV. S-polarized light reflects off the wire grid of these polarizers while p-polarized light is transmitted. These polarizers provide a wide acceptance angle, uniform brightness and contrast, and high grid uniformity. UV Wire Grid Linear Polarizers are used in biomedical, forensic, photo-alignment, spectroscopic, security, semiconductor manufacturing, and UV curing applications. Visible Wire Grid Polarizers and Infrared (IR) Wire Grid Polarizers are also available. Note: These polarizers should be handled with care to avoid touching the wire grid surface to prevent damage to the part. Specifications General Type: Linear Polarizer Note: When the Reference Mark is oriented to the 3 or 9 o’clock position, the transmission axis runs left to right.
