With a single click, our technology gauges the thickness of thin films by examining their light-reflective properties. This approach allows us to measure films ranging from an ultra-thin 1nm to a substantial 3mm in thickness, all while analyzing light wavelengths imperceptible to the human eye. Additionally, our film thickness measurement instruments feature a non-mechanical design, ensuring speedy results within seconds, encompassing film thickness, color, refractive index, and even surface roughness.
