Achromatic quartz-MgF2 zero-order waveplates consist of two different birefringent crystals—crystalline quartz and magnesium fluoride (MgF2)—each with a highly efficient broadband antireflection coating, in an air-spaced design. This construction ensures excellent transmitted wavefront quality, while minimizing beam deviation and surface reflection losses.
Because of the air-space design, achromatic quartz-MgF2 wave plates have a higher damage threshold than achromatic polymer film wave plates. Achromatic quartz-MgF2 wave plates are also less expensive than achromatic polymer film wave plates.

| NOTES! |
|
|
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. |
