POL-15 polariser

Laser Components' laser beam polariser is an adjustable rotation mount that holds either a half waveplate where the polarisation of the input beam is rotated by 90 degrees, or a quarter waveplate where a linearly polarised beam is converted to a circularly polarised beam and the axis is rotated by 45 degrees.

A retardation plate can be inserted into the plug-in holder and then be rotated by hand. The POL-15 features a cartridge design in anodised aluminium with a ø15mm clear aperture.

Other optics can be inserted into the  POL-15 as well, for example, a cylindrical lens, which will modify a round laser beam into a line.
