These dual wavelength multiple order waveplates are made a piece of quartz which has been precisely polished. Its thickness is controlled to provide half wave retardation at one wavelength and full wave retardation at a second wavelength.

They are offered for Nd:YAG harmonic wavelengths and can be used to separate the harmonic beams by means of a change in their state of polarization. A half wave plate has a net retardation of π and rotates the plane of polarization by 90°.

A full wave plate has a net retardation of 2π and rotates the plane of polarization by 180°. The two harmonics will therefore emerge with crossed linear polarizations.

NOTES!  
Half wave retardation at λ1,Full wave retardation at λ2.
The surface flatness is the reflected wavefront distortion of the surface before coating.
Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
