BOULDER, Colorado (March 30, 2007): Precision Photonics Corporation (PPC), a leading provider of ultra-precise optics and opto-mechanical assemblies, announces a new line of laser-line non-polarizers for visible and near-infrared applications. Like our wide selection of high-energy polarizing beamsplitters and beam combiners, these components utilize PPC’s advanced ion-beam-sputtering (IBS) coatings and Telecordia-qualified CADB™ epoxy-free bonding technique to provide you with stable, low-loss optical elements that are both athermal and suitable for high power applications.
The phase-preserving all-dielectric designs achieve polarization separation of less than 5% in both transmission and reflection with a 50/50 split ratio. Typical applications include phase sensitive heterodyne detection, optical demodulation and as components in Michelson interferometers used for dispersion compensation and interleaving.
Custom non-polarizing beamsplitter cubes are available at 1550nm with a phase separation of less than 10 degrees. Cube sizes range from 1mm to 25mm with angle tolerances as low as 30 arcseconds and transmitted wavefront error of less than /10 at 633nm. Non-polarizing plate beamsplitters can be manufactured at a variety of wavelengths from 500-2100nm with damage thresholds in excess of 5J/cm2 at 1064nm.
