The invention relates to an optical element used for precision measurement, based on the principle of total reflection optics.
In a normal cone mirror, the light will reflect on three faces, so that the observer can see the inside of the corner, but in a hollow cone prism, because the central part is hollow, it is the absence of a reflecting surface, so the light will not pass through the central part but will be reflected to the side of the prism, thus forming a bright point of light.
By measuring the position of this light spot, the Angle and orientation of the prism can be calculated, thus achieving precise measurement.
At the same time, the hollow pyramid prism can also be used for the separation and reflection of the reflected beam, which is widely used in the field of high-precision optical measurement, optical sensor, laser equipment and so on.
