Description

TF200 thin film thickness measurement system uses thin film interference optical principle to measure and analyze thin film thickness. The thin film surface is illuminated with a wide spectrum light source from deep ultraviolet to near infrared, and the probe receives the reflected light in the same position. TF200 quickly inverts and calculates the thickness of the thin film based on the reflected interference light. The measuring range 1nm-3mm can complete the test of multilayer film thickness at the same time. For 100nm films, N and K values can also be measured.

Features

Fast, accurate, non-destructive, flexible, easy to use and cost-effective.
