Waveplate Precision Photonics

In addition to 1” diameter half-wave and quarter-wave retardation plates, PPC also stocks 4” diameter compound zero order waveplate wafers. These large retarders can be sold as-is, core-drilled or diced to almost any size or shape in just a day or two, and they are already coated with our high energy, low loss ion beam sputtered (IBS) anti-reflection coatings.

PPC uses laser-grade crystal quartz to produce multiple-order,
true zero-order and compound zero-order waveplates with retardations
of quarter-wave, half-wave or anything in-between.
Multiple-order retarders are ideal for narrow- or single-wavelength
applications at a specific operating temperature. For increased
bandwidth and thermal stability, zero-order waveplates
are recommended.

For compound zero-order waveplates and multi-element waveplate
assemblies, we use durable IBS coatings and our proprietary
epoxy-free bonding technology—Chemically Activated Direct
Bonding™ (CADB). This unique combination of processes results in
precise, high-energy components that exhibit environmental stability
and improved transmitted wavefront characteristics.
Waveplates are available as standalone components, or as part of
a more complex optical assembly. PPC manufactures custom crystal quartz and sapphire waveplates and multi-element polarization assemblies from 1 mm to 1" for research, semi, biomedical and aerospace applications.
