Achromatic Waveplates

we has special designed achromatic waveplates by using two pieces of plates.It is similar to Zero-order waveplate except that the two plates are made from different materials,such as crystal quartz and magnesium fluoride. Since the dispersion of the birefringence can be different for the two materials,it is possible to specify the retardation values at a wavelength range, From the curve, you can see that the bandwidth of such achromatic waveplate is very wide ,while the achromatic waveplates remain a nearly constant retardance over a range of wavelength

Spectrally Flat Retardance
Operating Ranges from UV to Beyond Telecom Wavelengths
AR Coatings for: 260 - 410 nm, 400 – 800 nm, 690 – 1200 nm, or 1100 – 2000 nm
Quarter- and Half-Wave Plates Available
Custom Designs Available Upon Request
