Optical square


The optical square uses a pentaprism to reflect and refract a beam or sighting 90 degrees, it is used in pairs in surveying and in a singular block in metrology. In optical square A Horizon glass is placed at an angle of 120° with the horizon sight. The Index glass is placed at an angle of 105° with the Index sight.

Optical square definition is - a small hand instrument used by surveyors for laying off a right angle by means of two mirrors set at an angle of 45 degrees.

Optical Square a very simple geodetic instrument that is used to lay off angles that are multiples of 90° or of 45°. In a prism square (see Figure 1), the direction of a ray originating from the flag on the right is changed by 90° after refraction and internal reflection.
