Achromatic Waveplates
from Dayoptics, Inc.

Dayoptics 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... [See More]
