The 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 |
| |
»| We are committed to support a fast delivery to customer.Generally,we can delivery any wavelength for standard size within 10-15days if no stock. |
| |
»| We hold a large stock for most standard size with standard wavelength,it will satisfy most applications and test. Please contact us for checking our stock situation and information. |
| |
»| Custom retardation and size is avaliable upon request, and please advise us your central wavelenght when you order our standard dual wavelength wave plates. |
| |
»| 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. |
