3 Overview
The shape of the light-cutting microscope is shown in Figure 1. It measures the surface roughness by the principle of light-cutting measurement (Fig. 2).
Contour peak height and valley depth, the measurement range (1.0~80) μm.

4 Measurement characteristics
4.1 Measuring microscopic eyepiece field of view and indication error
When the micrometer eyepiece drum indicates the zero position, the millimeter line of the micrometer eyepiece reticle shall be placed in the double scribe line index.
In the field of view of the instrument, the image of the slit image and the object to be measured should be clearly adjusted at the same time, and in the center of the field of view, it is clear
