An autocollimator is an optical instrument for non-contact measurement of angles. They are typically used to align components and measure deflections in optical or mechanical systems.

What is an autocollimator? An autocollimator is an optical instrument used for the high-precision measurement and correction of the angular alignment of a reflective surface.

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 …

Autocollimator as an optical instrument was invented around a decades ago for precise, non-contact measurements of angle. It has a lengthy history of being utilized in the alignment of …

May 18, 2024 · The autocollimator is an optical instrument which is used for the measurements of small angular differences, changes or deflections. It is also used to determine straightness, …

Mar 14, 2025 · An autocollimator is an optical instrument specialized for angle measurement and is indispensable for inspections and adjustments that require high accuracy.

The fundamental principle of an autocollimator involves directing a collimated beam of light towards a flat, reflective surface, such as a mirror. The term ‘collimated’ refers to a beam with …

The Ultra autocollimator used with the adjustable base, side feet and mirror allows fast and accurate 2 axis straightness measurement on machine tool slideways.

The autocollimator measures the deviation between the emitted beam and the reflected beam. Because the autocollimator uses light to measure angles, it never comes into contact with the …

Jun 13, 2025 · An autocollimator is an optical instrument that uses a beam of light to measure the angle between a reference surface and a target surface. It works on the principle of …
