Autocollimators are optical measuring instruments that can measure the smallest changes in the angular position of optical reflectors. In electronic autocollimators, the autocollimation image is detected by means of CCD lines or a matrix sensor. Electronic autocollimators are primarily used for the following measuring tasks: small angle measurement, ultra-precise angle adjustment and calibration, quality assurance of machine tools and their components, assembly automation, angular position monitoring. The ELCOMAT® family of electronic autocollimators offer a wide range of instruments suitable for every application and budget.

With the direct signal digitization in the sensor head, the high user-friendliness and extended functions of the display unit 5000 the Möller-Wedel Optical ELCOMAT® vario N sets a new standard in the ELCOMAT® product line. Like its predecessor ELCOMAT® vario D, the low-cost ELCOMAT® vario N autocollimation sensors can be supplied with a wide range of objective tubes. This variety allows you to choose the most suitable ELCOMAT® vario N for your specific measuring task.

Measuring tasks

Electronic autocollimators are primarily used for the following measurement tasks:

  • Smallest angle measurement
  • Ultra-precise angle adjustment and calibration
  • Quality assurance of machine tools and their components
  • Assembly automation
  • Angle position monitoring

Measuring principle

Autocollimators are optical measuring instruments that can measure the smallest changes in the angular position of optical reflectors. In electronic autocollimators, the autocollimation image is detected by means of CCD lines or a matrix sensor.

Measuring range and measuring distance

The measuring range of any autocollimator decreases with increasing measuring distance. The measuring accuracy of autocollimators is independent of distance, negating environmental influences. With the autocollimators of the ELCOMAT® series, the measuring range remains constant up to a certain measuring distance and then decreases with increasing distance between the autocollimator and the mirror. The typical measuring range at different distances is listed in the technical specifications of the ELCOMAT®vario N product series.
