Product Family Description

  • 50% Reflection / 50% Transmission
  • Beam Deviation Insensitive to Alignment
  • Designed for Visible Wavelengths

Penta Prism Beamsplitters are constructed by cementing a precision penta prism and a wedge prism together, and applying an appropriate interference coating to one of the traditionally reflective surfaces. Since slight movements of a penta prism do not affect the true right angle at which light rays are reflected, the deviation between the transmitted and reflected light rays is highly controllable and will not vary by more than 10arcsec.

Note: Outgoing beams are partially polarized.
