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... [See More]

Achromatic Waveplates – Cemented
from Tower Optical Corporation

Tower Optical offers this second series of Achromatic Waveplates (AWP ’s) which are built using 25.4 mm substrates of crystal quartz and magnesium fluoride. These substrates are cemented together. This technique helps to control costs by reducing the number of surfaces requiring AR coating... [See More]
