Plastic Retarder 280nm Retardance 150x150x0.8mmthk
|Description||Visible 1/2 wave|
Plastic retarders are a cost effective alternative to mica or quartz which are generally 0.8mm thick and available in large sizes. Our stock range includes one wave plates which can be used as sensitive-tint plates in polariscopes to display small strain in a specimen by colour differences.
Our stock plastic retarders are available in both half-wave and quarter-wave types between 140-560nm and can be purchased directly from this page. Knight Optical also offer an extensive custom optics service thanks to our many years experience in the industry, and we are able to cut and shape plastic retarder sheets to size to fit individual applications.
