Multi Order Wave plates(1/2 and 1/4 waveplates) are made from a single crystalline quartz plate. Retardation varies quickly with wavelength, thus they are generally useful only at their design wavelength. Retardation is also a function of plate thickness and is slightly temperature dependent due to thermal expansion.

| 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. |
