Zero Order Wave plates(1/2 and 1/4 wave plates) are made from two crystalline quartz plates of similar thickness, that are optically contacted together with orthogonally aligned optical axes. Retardation varies slowly with wavelength, thus they are useful with tunable or broadband sources. Retardation is a function of thickness difference between the two plates, and is essentially invariant with temperature.
Non-coated and AR coated products are available.

| NOTES! |
|
|
Custom retardation and size is avaliable upon request. And please advise us your central wavelenght when you order our standard multi order wave plates |
|
These products can be used for the beams which wavelengths are in +/-1% of rated wavelengths. |
|
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. |
