Inversion Fitting
Inversion fitting is the key step of adjustment. The speed and accuracy of the inversion fitting directly determine the efficiency and product quality.
Thickness of each layer is inverted according to the thin film stack and known spectrum by Solving equations with many strategies.
We can get the adjusted thickness through comparing simulated thickness with the standard thickness.
Through the step-by-step inversion fitting, you can adjust the actual thin film thickness to the standard thickness resulting in the desired spectrum, color And physical characteristics.
