Glan Thompson Polarizer

Brand :Dayoptics

Product origin :Fuzhou,Fujian,China

Delivery time :4 week

Supply capacity :1000pcs/month

Glan Thompson polarizer is made of two calcite prisms or two a-BBO prisms cemented together .
Two types of Glan Thompsons are available .One is the standard form and the other is the long form.Their length to aperture ratios 2.5:1 and 3.0:1 respectively.Glan Thompson polarizers tend to have higher extinction ratio than air spaced polarizers .In the ultra violet spectrum,their transmission is limited by absorption in birefriengent materials as well as the cement layer.a-BBO polarizers and Calcite polarizers can be used from about 220 to 900nm and 350 to 2300nm respectively.
