The electronic autocollimator is a high precision angle measurement instrument capable of measuring angular deviations with accuracy down to fractions of an arcsecond, by electronic means only, with no optical eye-piece.

The two main principles used in an autocollimator are (a) the projection and the refraction of a parallel beam of light by a lens, and (b) the change in direction of a reflected angle on a plane reflecting surface with the change in the angle of incidence.

The basic principle of an autocollimator is simple: one directs a collimated beam, which by definition has a small beam divergence, to a flat reflecting object (a mirror) and detects the angular position of the reflected light, which typically needs to be close to direct back-reflection.

The TriAngle electronic autocollimator is the standard and most universal instrument of the TriAngle series. Variable measuring range and accuracy performance between 2.5 and 0.2 arcsec depending on the focal length

The autocollimator is a very sensitive angle measuring device and is thus used for the precise angular adjustment of optical or machine components. Due to the collimated beam (infinity adjustment) the measurement results are independent from the distance to the object under test.

An autocollimator is an optical instrument used to measure small angular differences with high accuracy. It combines the functions of an infinity telescope and a collimator, primarily used to align optical components and measure optical and mechanical deflection.

An autocollimator is a precision optical instrument used to measure small angles and alignments with high accuracy. It is essentially a telescope that projects a light beam onto a target and then measures the reflection of this beam to determine the angle or alignment of the target surface.

The autocollimators are basically used to align the different components of a system together and measure their mechanical or optical deflections. When a monochromatic light source’s beam of light rays is made to fall on a beam deflector, it deflects the beam into 90 degree towards the converging lens.
