Electric automatic collimator is a high-precision optical measurement device mainly used for detecting parameters such as straightness, flatness, and perpendicularity of guide rails. It is widely used in mechanical processing, optical component calibration, and other fields.
The light passes through the dividing plate located at the focal plane of the objective lens and forms parallel light through the objective lens. Parallel light is reflected back by a mirror perpendicular to the optical axis, and then forms a reticle image on the focal plane after passing through the objective lens. When the mirror undergoes angular deflection, the image of the returned reticle on the photoelectric sensor will be displaced. By accurately measuring this displacement value, the deflection angle of the planar mirror can be accurately calculated.
It usually consists of electronic eyepiece, objective tube, two-dimensional adjustment base, reflector, control measurement software, and other parts. The electronic eyepiece is used to capture the reflected cross image, the photoelectric sensor receives information from the image, and the measurement software displays and analyzes the data in real time.
