SO-P12 SERIES
SO-P12 K9 pentaprisms deviate a beam by 90 degrees with substantially less sensitivity to small prism rotations than a simple mirror. They are used in metrology, surveying, alignment systems and optical instruments that need a stable right-angle reference.
Product Overview

Engineering Guidance
Choose the prism around beam geometry and angular accuracy
Optical behavior
Models are defined by A, B, C and D dimensions, beam-deviation tolerance and coatings on the reflective and entrance/exit faces. Reflective faces use protected aluminum while transmission faces use MgF2 antireflection coating where specified.
Selection and handling
A pentaprism fixes beam deviation but does not correct all mounting errors; reference the optical faces and preserve coating orientation in the housing.
Need a different diameter, tolerance or coating?
Custom substrate materials, dimensions, angular tolerances and coating bands can be reviewed for prototype and production quantities.
