Air Spaced Zero Order λ/2 Half Wave Plate, High Damage Threshold

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
