Thin Film Thickness Measurement Instrument
1 unit
Made in China


  Incident lights with wavelengths range between 200-1700nm vertically shine on the surface of thin film, when transmittance of thin film happen, ATGX310 can utilize lights reflected via upper and lower boundaries of thin film to create an interference pattern superimposed, the spacing of the pattern’s sinusoidal waves, when combined with the refractive index of the material, can be used to calculate the thickness of the materials.
