Air Spaced Zero Order λ/4 Quarter Wave Plate, High Damage Threshold Overview: Air spaced zero order wave plate is built by placing a
spacing ring between the two multi-order wave plates to form an air
gab between them. The slow axis of one waveplate is aligned with
the fast axis of the other waveplate. To achieve the required
retardace will request carefully match the thickness differences of
the two multi order waveplates. For high power lasers and
applications require to withsthand high damage threshold, air
spaced zero order waveplate is certainly a good choice. Main Features of Air Spaced Zero Order Wave Plate: - Air spaced double-plate sturcture
- Broad working spectral bandwidth
- Superior in temperature sensitivity and retardation steadniess than
lower order waveplates
- Withstand high damage threshold and support high power lasers
