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.
Waveplates are available as standalone components, or as part of a more complex optical assembly. PPC manufactures custom multi-element polarization assemblies with and without epoxy in sizes from 1 mm to 4" for R&D, biomedical and aerospace applications.
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.
All of our waveplates and waveplate assemblies are adhesive free, making them suitable for high power applications with energy densities exceeding 20 J/cm² at 1064 nm.
Rapid Prototypes, any shape, any size!
In addition to 1” diameter standard retardation plates, PPC also stocks 4” diameter compound zero order waveplate wafers for 1064 nm. These large retarders can be sold as-is, core-drilled or diced to almost any dimension in just a day or two, and they are already coated with our high energy, low loss IBS anti-reflection coatings.
