Air-spaced Achromatic Waveplates are constructed of Quartz waveplate and MgF2 waveplate, air-spaced to allow for use with high power applications. The use of crystalline Quartz with MaF2 minimizes the wavelength dependence of the retardation such that a nearly flat spectral response is achieved over the entire operating range of the achromatic wave plate. The flat response of an Achromatic Waveplate is ideal for use with tunable lasers, multiple laser-line systems, and other broad spectrum sources.

Features:

- Higher Damage Threshold

- Four broad spectral ranges

- Spectrally Flat Retardance

- Retardations of λ/2 and λ/4
