What's new in OptiLayer in 2013 (version 9.96)
Novel Monochromatic Monitoring Strategy
OptiLayer has several new options for specifying various monitoring strategies:
The ability to use BR and BR color characteristics in monitoring spreadsheets has been introduced.
A really breakthrough innovation is the introduction of a new automatic option for generating monitoring spreadsheets:
This option, referred to as Strategy 4, is aimed at generating monitoring spreadsheets for a wide set of direct and indirect monochromatic monitoring techniques that explore corrections of termination levels based on monitoring signal extrema registered during layer depositions. Successful implementation of these techniques implies certain demands for signal starting and termination level deviations from adjacent signal extrema.
The Strategy 4 allows you to specify a set of such demands that are then taken into account by the algorithm generating a monitoring spreadsheet:
