Air spaced Zero Order waveplates are are constructed of two Quartz waveplates, air-spaced to allow for use with high power applications. The fast axis of one plate is aligned with the slow axis of the other, with an optical path length difference of λ/4 or λ/2. Compound zero-order waveplates provide wide tunability about the design wavelength. They also offer excellent temperature stability as temperature effects of the two components parts tend to cancel out.
Features:
- Higher Damage Threshold
- Center Wavelengths from 266 nm to 2020 nm
- Relatively insensitive to wavelength and temperature variation
- Retardations of λ/2 and λ/4
