Rapid changes in production demand require "fast track" installation of complex thin film processes.  Minimising development time keeps throughput high and reduces costs.  Initial theoretical design is just the start in a new process for complex optical stacks.  The performance of the coating sources must be optimised for the exact materials and layers being processed, the optical properties of the coating must be controlled by Broad Band Optical Monitoring and individual layers terminated at just the right time to hit target spectra in the film design. Optics Toolbox integrates all these processes. A proprietary strategy generator takes input from standard software packages like Filmstar^TM, Optilayer^TM, or TFCalc^TM to define end points for each layer using the GSM broadband monitor.  Evatec's " Khan" system and process controller then offers seamless execution on either the BAK evaporation or MSP sputter platforms.
