Broadband Achromatic Waveplates

Broadband Achromatic Waveplates
Broadband Achromatic Waveplates 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),  465-650 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 and rotation mounts 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.
