Dichroic Waveplates
Dichroic waveplates are constructed as a single plate. For the two wavelengths which have to be combined, we design the best possible retardation. Combinations may be:
L/2 & L/2
L/4 & L/4
L/2 & L or L & L/2
L/4 & L or L & L/4
Achromatic Waveplates
Achromatic waveplates are constructed with two plates that are air spaced mounted. For this purpose the materials Crystalline Quartz and Magnesium Fluoride are combined. We design the best possible retardation for the required spectrum.
