Leaving the autocollimator in the same position, the optical square and reflector are then moved to the second rail and the measurements repeated. Figure 2 Note - it is imperative that the autocollimator is not moved from the first rail position as this is the reference line. The out of squareness (parallelism) between the two rails is the A new method to calibrate the autocollimator with small angle measurement range has been developed. This method used a system based on rotary encoder for angle measurements with self-calibration function (SelfA47). The SelfA47 has 18,000 graduation lines with angle interval of 0.02°, corresponds to 72 arcsec. Thereby this system cannot be used to calibrate the autocollimator with measurement 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. Autocollimator - working Principle and Application. To understand this, let us Open the catalog to page 2. Autocollimation in practice Checking, measuring, indexing & monitoring Taylor Hobson Autocollimators are used in conjunction with reflecting mirrors or surfaces for the accurate measurement of small angular deviations from a datum angle. The main advantages of Taylor Hobson autocollimators are: • igh accuracy Autocollimators 6B-LED/6D-LED. Autocollimator is an easy-to-use but precise metrology instrument for angularity, parallelism, perpendicularity, straightness of precision components, machine guide-way and many other applications.
