1401 type bidirectional precision autocollimator

Double directional precision autocollimator 1401 type
Product Introduction:
The 1401 type bidirectional precision autocollimator adopts the optical autocollimator principle and two-dimensional measurement structure, which can accurately measure the motion straightness and flatness of machine tools, instrument precision guides, and precision flat plates, as well as the angle and linear values in horizontal and vertical two-dimensional directions. Its work efficiency is better than that of current unidirectional similar instruments.
The bidirectional precision autocollimator 1401 type is suitable for measurement units at all levels, research institutes, college laboratories, and factory measurement rooms, especially for workshop processing and installation and commissioning sites.
1. The main body of the instrument is used in conjunction with a flat reflector to measure the flatness of workpieces and flat plates.
2. Used in conjunction with optical angle sensors and magnetic reflectors, it can measure the straightness and perpendicularity of vertical rails.
3. Used in conjunction with polyhedral prisms, it can measure the circular indexing error of the dial.
4. The viewfinder is an optional component for this machine, which can be used in conjunction with the host for self collimation measurement, making the operation quick and easy.
