Warm congratulations to JINCHEN for purchasing new testing instruments such as 2 microscopes in the new year of 2025. 2 projectors and 2 2.5-dimensional. As we all know, testing equipment is the most important part of the entire shipment. He determines whether the goods are produced up to standard. If there is no equipment without quality testing equipment. Suppose a customer receives a defective product, which will cause huge trouble to the customer. Next, I will introduce to you the interference microscope purchased by the company.
Interference microscopes consist of interference and microscopy systems and use the principle of light wave interference to measure surface roughness parameters. It uses the wavelength of light in the range of (530~600)nm (1nm=10-9m, symbol nm. 1nm=1 nanometer, which is one billionth of a meter) as the ruler, and compares the measured surface with standard optical The mirror surface is compared, and then the microscopic geometric shape characteristics of the measured surface are observed and measured through high magnification of the microscope system. The double-beam interference microscope is mainly used to measure the surface roughness evaluation parameter RZ. This instrument can be used to measure the surface of precision machined parts such as planes, cylindrical surfaces, etc. It can also be used to measure the depth of the surface markings, coatings, etc. of the parts.
The interference microscope is an instrument that uses the principle of light wave interference to inspect the surface roughness of the workpiece. The interference microscope uses a plane mirror as a reference mirror and the surface of the part to be measured as a measuring mirror. It uses the principle of the Michelson interferometer to generate interference fringes. By measuring the bending amount of the fringes, the surface roughness value is obtained.
