Low Order Waveplates

Waveplates

Waveplates, also known as retardation plates, are optical element having two principal axes slow and fast, that resolve an incident polarized beam into two mutually perpendicular polarized beams. The emerging beam recombines to form a particular single polarized beam. Retardations plates produce full, half, quarter and octadic-wave retardations.

Low order waveplates

The properties of low order waveplates are much better than the multi-order wave-plates because of its thinner thickness (less than 0.5mm). Better temperature (38), wavelength (1.5nm) and incident angle (4.5�) bandwidth and high damage threshold make it widely used in common application. Also it is economical.


Key features:
-thickness: 0.2-0.5mm
-high damage threshold
-better temperature bandwidth

-low cost
