Wire Grid Polarizer Standard sample

Key Features

・Excellent heat resistance compared to organic
polarizers.
・It is particularly advantageous for applications requiring environmental durability.

・SCIVAX can provide customized wire grid polarizers depending on your application requirements, whatever parameters you need to enhance (high contrast, high transmission, wide incident angle, surface protection…)

Typical Performance of MRLS1

How to function

When the metal grid pitch is less than half of the
wavelength, diffraction is suppressed and it
functions as a polarizer.
