Broadband Achromatic Waveplates

Consisted of one quartz and one magnesium fluoride plates
with the optical axes orthogonally oriented.
Air-spaced design for high transparency and high power applications.
Different designs to cover extremely broad bandwidths:
350-470 nm (UV-UV/Blue), 465-660 nm (VIS), 650-1100 nm (NIR)
920-1350 nm, 1000-1750 nm (IR1), 1400-2200 nm, 1650-2650 nm (IR2)
Two plate sizes available:
Diameter 15mm, mounted in OD 1" holder and
Diameter 1" (25.4 mm), mounted in OD 30 mm holder
Mount adaptors are available.
