Description
SM280 is a microfilm thickness mapper developed by utilizing the principle of reflection light interference of films. It uses the light with the widest wavelength range of 200-1700nm to be vertically incident on the surface of the film. As long as the film has a certain degree of transmission, the SM280 can calculate the film thickness according to the reflected interference spectrum, and other optical constants such as Reflectivity, refractive index and extinction coefficient, etc., the thickness of the maximum mapping range can reach 10nm ~ 100μm.
The SM280 automatic microscopic film thickness mapper adopts a microscopic system, which can further reduce the spot size, thereby achieving very good spatial resolution. At the same time, the SM280 adopts an integrated design. The core components use a high-resolution, high-sensitivity spectrometer and a high-precision 3-axis mobile platform. Combined with Optronics' unique algorithm technology, it provides users with a new generation of leading automatic microscopy film thickness Surveyor.
