9J Optical sectioning method for measuring microscopeDetailed product description：

Product Introduction
The 9J light cutting method measuring microscope is used to measure the micro roughness of the machined surface of another piece using the light cutting method. It can judge the surface smoothness of ▽ 3- ▽ 9 levels specified in the national standard GB 1031-68. (Surface roughness 12.5-0.2) The depth of surface scratches, lines, or certain defects can also be measured.
Light cutting microscope

Features:
The characteristic of the light cutting method is that it is carried out without damaging the surface. It is an indirect measurement method. The unevenness of the texture can only be determined after calculation.
