Overview: Air spaced zero order waveplate 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. The slightly different
thickness of the two multi order waveplates is chosen to achieve
the required retardance. Air spaced zero order waveplate is
designed for high damage threshold supporting high power lasers. Main Features of Air Spaced Zero Order Wave Plate: - Air spaced double-plate sturcture
- Wide working spectral bandwidth
- Low temperature sensitivity and better retardation steadniess than
lower order waveplates
- High damage threshold supporting high power lasers
