Simple technique for the fabrication of a penta prism with high accuracy right angle deviation.

Abstract

What we believe to be a new technique for the fabrication of a penta prism (PP) with high accuracy right angle deviation of the incident beam is presented. We derive simple formulas relating to the error in right angle deviation with the errors in 45 degrees (beta) and 90 degrees (delta) angles of a PP, and we determine error in right angle deviation from… (More)
