Sign up now to be one of the first to receive PPC’s 2011 Capabilities Brochure and Catalog.

Due out in December 2010, the updated catalog will include an expanded list of standard products as well as information on new capabilities, current R&D efforts and innovative applications.

New capabilities include custom MWIR coatings, 2.1 μm polarizers, large optics and superpolished substrates.

To complement our 3" and 4" diameter wafer, mirror and waveplate capabilities, Precision Photonics has brought a new IBS coating chamber online that will be capable of coating high-energy laser components of up to 10" in diameter.

With the help of an SBIR grant earlier this year, we have spent most of 2010 modeling and testing various coating configurations in order to ensure both repeatability and uniformity across a larger substrate area.

By 2011, we will be able to manufacture large aperture mirrors, windows and beam-splitters for applications throughout the UV, VIS and NIR wavelength regions. Please call 303-444-9948 for more information or email your requirements to sales@precisionphotonics.com for a formal quotation.

High Energy Broadband Beam Splitters

Among the many diverse custom precision optical components that PPC offers are broadband low dispersion polarizers and super broadband polarizing beamsplitter cubes.

All of PPC's beamsplitter cubes are derived from a unique combination of ion beam sputtering coatings, ultraprecise fabrication capabilities and our patent-pending, epoxy-free bonding technology-Chemically Activated Direct Bonding™ (CADB^®) which results in a zero-bondline, zero residue interface at the hypotenuse. Thus, they are environmentally stable and exhibit high laser damage thresholds in both reflection and transmission, making them ideal for high-power broadband, Nd:YAG and fiber laser applications where fluences are greater than 500 mJ/cm² and calcite or cemented cube polarizers cannot be used.

Our low dispersion design offers an epoxy-free, broad bandwidth from 700-1000 nm with a low GVD, dielectric coating specifically designed for femtosecond laser applications.

The super broadband polarizer cube maintains a > 500:1 extinction ratio throughout the entire Visible to Nir-Infrared (400-1100 nm) without sacrificing overall transmission or damage threshold (> 6J/cm²!)

Superpolished Surfaces < 1 Å RMS

PPC has expanded our super-polished capabilities to include batch size polishing of Fused silica, Terbium Gallium Garnet (TGG), single crystal sapphire (Al2O3) and Ti:Sapphire glass. Plano substrates of up to 3" diameter can be polished to better than λ/10 surface flatness with 10-5 surface quality and surface roughness of less than 1 angstrom RMS (as shown).

Super-polished or laser quality polished substrates and assemblies are ideal for use as low-loss laser mirrors, high energy waveguides and in cavity ring-down spectroscopy (CRDS) where thermal stability, surface scatter and high laser damage thresholds are key requirements. We can also provide ion-beam-sputtered (IBS) anti-reflection, beam splitter and high-reflection coatings on these and other materials at wavelengths from 266 nm to > 3 μm.
