Description
SM230 is an automatic thin film thickness mapper developed by utilizing the principle of thin film reflected light interference. It uses the light with the widest wavelength range of 200-1700nm to vertically incident on the surface of the thin film. As long as the film has a certain degree of transmission, the SM230 can calculate the thickness of the thin film according to the reflected interference spectrum, as well as other optical constants such as reflectivity, refractive index and extinction coefficient, etc., the thickness of the maximum mapping range can reach 5nm ~ 250um.
The SM230 automatic optical thin film thickness mapping instrument is constructed by the surveying and mapping host, the surveying and mapping platform, the Y-type optical fiber and the host computer software. technology, providing users with a new generation of leading automatic optical film thickness mappers.
