LED digital photoelectric autocollimator
An autocollimator is an optical instrument that is used to measure small angles with very high sensitivity. As such, the autocollimator has a wide variety of applications including precision alignment, detection of angular movement, verification of angle standards, and angular monitoring over long periods.
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.
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. An autocollimator works by projecting an image onto a target mirror and measuring the deflection of the returned image against a scale, either visually or by means of an electronic detector. A visual autocollimator can measure angles as small as 1 arcsecond (4.85 microradians), while an electronic autocollimator can have up to 100 times more resolution.
Autocollimators are used by the optical industry and mechanical engineers in a variety of applications. Their specific functions include precision alignment, the detection of angular movement, the verification of angle standards, and angular monitoring over long periods.
Autocollimators can be used in the testing of
l parallelism with a collimator and telescope
l paque wedges and plane parallel plates
l transparent wedges
l angles in glass prisms
l the accuracy of rotary tables and index tables
l camera objectives
These optical instruments are also used in the flatness testing of reflecting surfaces, the control of wedges and plane parallel plates, and parallel measurement of cylindrical bores.
