Custom Hollow Penta Mirrors (HPM)

Product Announcement from PLX Inc.

Custom Hollow Penta Mirrors (HPM) -Image

The Hollow Penta Roof Assembly is a constant deviation device developed by PLX to duplicate, with advantages, the performance of a penta prism. Unlike a solid prism that is limited in transmission through glass, the new device utilizes front surface reflectance, and thus is unlimited in wavelength transmission. By modifying the coating, polarization of the exiting beam can be precisely controlled. The device enables incoming parallel light to be deviated at 908 with great accuracy. Like the solid prism, the assembly is an invariant, and thus permits movements such as rotation without compromising either the basic 908 deviation or its inherent accuracy.

The optical elements of the hollow penta roof assemblies are monolithic structures made of fine annealed borosilicate glass. They are mounted in an aluminum enclosure, with a black anodized finish. Type A and Type B are each available in 1/2", 1" and 2" clear aperture, with accuracies to better than 1 arc sec.

  • Performance of a penta prism with more control and wavelength transmission.
  • Invariant assembly permits movements without compromising deviation or accuracy.
  • Accuracies to better than 1 arc second. Request a custom quote, specify what your application is and our engineering staff will get back to you.
