Description

Details

Displacer produces two parallel orthogonally polarized beams from an unpolarized input. The displacement between the ordinary and extraordinary polarized beams can be found from an approximate formula d=0.1xL.

Beamdisplacers of other size, higher specifications, different spectral ranges, housing or AR coatings are available on request.

Beamdisplacers can be made from crystal quartz and rutile as well.

Features

Splits a beam into two orthogonaly polarized divergent beams
Made from the finest optical grade natural calcite or YVO4
