CoatFlex

CoatFlex Calculation Engine​

CoatFlex is a self-developed high-performance optical thin film calculation engine that performs all thin film-related operations, including film stack design optimization, reverse engineering, refractive index fitting, and spectrum calculation.

Integration Features​

CoatFlex is fully integrated into the OSC Low-E system:

  • Automatic Operation: Runs automatically in the background without manual startup
  • No Manual Control Required: All calculations are triggered automatically without user intervention
  • Seamless Integration: All calculation functions work transparently
  • High Performance: Developed in Rust, optimized for production environments

Usage​

CoatFlex is automatically available in the following modules:

  • Development Module: Film stack design and optimization
  • Reverse Engineering Module: Calculate layer thicknesses from measured spectra
  • Index Fitting Module: Material optical constants fitting
  • Process Master Module: Process control and uniformity adjustment

All optical calculations are handled automatically by CoatFlex without user intervention.

Technical Features​

  • Transfer Matrix Method (TMM): Accurate multilayer thin film optical calculations
  • Analytical Jacobian Matrix: Efficient derivative calculations to accelerate optimization convergence
  • Multiple Optimization Algorithms: Supports LM, Simplex, SA, DE, ACO and other optimization strategies
  • Color Calculation: CIE XYZ, Lab* color space support
