Air spaced two piece waveplates are suitable for use with high-energy lasers (no optical contact occurs). 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 broadband quartz waveplates for other wavelengths are also available, contact our Sales Division with you requests.
▶Standard thickness of Aluminum frame is 6mm (subject to differ without notice).
▶Optical axis is parallel to the edge of 14mm squared plate.
▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).

Attention

▶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.
