First of all, we must know the structure of the light-section microscope and be familiar with its use. Secondly, familiar with the principle of measuring the surface roughness by light cutting method Then deepen the understanding of the micro unevenness in the surface roughness evaluation parameters Light-cutting microscope, also known as double-tube microscope, is a measuring instrument that uses the principle of light-cutting to measure surface roughness. It is used to measure the ten-point Rz value of micro-roughness of 0.8-80um and the maximum height Ry value of the profile. The average spacing S value. The bending height of the light band image is measured with a micrometer lens. What are its experimental steps? 1. Measurement of micro-roughness ten-point height Rz 2. Measurement of the maximum height of the profile Ry 3. Measurement of the average spacing S of the single peaks of the contour The technical staff of Shanghai No.1 Optical Instrument Factory also left a question for readers, want to test everyone ~ Question: Can the average mean deviation Rz of the contour be measured with a light-cutting microscope? If you know the answer, please leave a message to Shanghai Optical Instrument Factory.
