Air spaced two piece waveplates are suitable for use with high-energy lasers (no optical contact occurs).For Nd-YAG lasers and Yb lasers, there is a lineup from fundamental to 4th harmonic.

Details

◦These products utilize birefringence of quartz and give phase difference of λ/4 (π/2, 90°) or λ/2 (π, 180°) to the input beams.
◦λ/4 retarders convert linearly polarization to circularly and circularly polarization to linearly. λ/2 retarders convert the direction of polarization arbitrarily.
◦Air spaced type waveplates are zero-order (first-order) retardation plates (phase plates) which are assembled from pairs of crystalline quartz plates and are mounted on aluminum frames.
◦Custom-made air spaced type waveplates for other wavelengths (248nm, 257nm, 308nm etc.) are also available.

Guide	Please contact our Sales Division for customized products. (Customized on size etc.)
Remark	-
Attention	Unlike multiple-order (higher-order) waveplates that are made from a single quartz plate, the net retardations of zero-order waveplates are almost not affected by temperature change. These products can be used for the beams which wavelengths are in +/−1% of rated wavelength. The surface flatness is the reflected wavefront distortion of the surface before coating. Be sure to wear laser safety goggles when checking optical path and adjusting optical axis. Standard thickness of Aluminum frame is 8.4mm (subject to differ without notice).
