​Lightwind Software Instructional Videos:  Endpoint Simulation and Test

​(Dependent on the version, Lightwind software screens may appear slightly different.  Operation and function are the same however.)

The Lightwind Endpoint SImulator is  designed to load a  full spectral data file so that different wavelengths can be tested as possible endpoint candidates.  Different endpoint algorithms provide choices of techniques that offer the most robust control. It is recommended that endpoint simulations are run on more than one sample to provide a statistically significant sampling of process variation.
