Air Spaced Achromatic Waveplate Series
from Tower Optical Corporation

Tower's achromatic waveplate (AWP) is similar to a zero-order waveplate, which is made from two pieces of crystal quartz except that the AWP is composed of one piece of crystal quartz and one piece of magnesium fluoride, MgF2. Both of these materials are birefringent, however, by proper matching of... [See More]
