Glan
Thompson Prisms
|
|
These polarizing prisms are the simplest form of calcite polarizer. They
are cemented, making them only useful for relatively low power applications.
They have a wide and symmetrical field of view and make extremely versatile
general purpose polarizers. The o-ray is absorbed in the material surrounding
the prism and the e-ray is transmitted. Two versions are offered having
different length/aperture ratios and consequently different angular fields.
These prisms are normally provided in a metal cell but since they are cemented
together they can be supplied unmounted if required.
