Thorlabs Toolkit

Get convenient access to photonics calculators, equations, and other information and resources when you download this free app! This application is being continually updated to offer new types of resources, as well as to expand existing categories, so be sure to check for updates. The current version of the app includes a collection of calculators that engineers and technicians at Thorlabs Lens Systems and elsewhere have used on the floor for over 15 years. Each calculator page includes the equations used in the calculations, as well as usage notes and information about assumptions included in the equations. Additional resources include brief summaries of ray tracing, lens theory, Snell’s Law, manufacturing tolerances, and evaluation of system resolution using the modulation transfer function (MTF). History Thorlabs Toolkit builds on the excellent foundation provided by the JML Optical Calculator. When JML Optical joined Thorlabs’ family as Thorlabs Lens Systems, it provided a wonderful opportunity to expand the app to share knowledge collected from across all of Thorlabs.
