Air Gap Type Waveplate / WPQG-25.4C-10640-2M
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.

◦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.

| 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). |
