Unlike quartz waveplates, Fresnel rhombs are inherently less sensitive to wavelength (i.e. achromatic) since the phase shift is a function of the glass index which varies only slightly over the design wavelength range. The wavelength varies less than +/-2% over a range from 600nm to 1550nm. Each Fresnel rhomb is designed for a l/4 wave retardance. The l/2 wave rhombs use two l/4 rhombs cemented together. We can also manufacture UV rhombs as well as air-spaced rhombs for high power applications. |
