Achromatic 0th Order 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)
775-1550 nm, 1000-1750 nm (IR1), 1400-2200 nm, 1650-2650 nm (IR2)
Two common plate sizes:
Diameter 15mm, mounted in OD 1" holder and
Diameter 1" (25.4 mm), mounted in OD 30 mm holder
Custom sizes are available upon request.
Mount adaptors are available

GDD introduced pulse broadening:

In the following table are the calculated output pulsewidths of transform-limited 20 fs pulses after transmission through the achromatic waveplates. The central wavelength of the applicable range of each waveplate is chosen as a representative wavelength for the calculation.
