Description
Idealphotonics manufactures wire grid style polarizer and filters for the terahertz band applications using our thin-film membrane platform.Wire Grid Terahertz polarizers are fabricated using MEMS processes and are ideally suited for industrial and research application in demanding environments such as extreme temperature and ultra-high vacuum conditions.Our wire grid polarizers have practically identical performance compared with similar free-standing wire grid polarizers.  Our standard polarizers are available in both unmounted style and mounted version.
