BEAM FOUR
Description
Our new open source policy makes the entire set of BEAM FOUR project source files public, under the GNU General Public License Version 2. The source code and full documentation can be downloaded from GitHub. Release 208 includes all the features of our previous releases: Multiple on-screen layouts with various views and scales that give you a variety of views of your optical system. Maps were added last year: these are color coded diagrams showing how your image quality varies over your field, or over a 2D parameter space. Combined with our MultiPlot feature -- which delivers a grid of spot diagrams -- you can explore how your design is influenced by the available parameter choices. Also included (starting back with release 128) are Gaussian scattering surfaces that let you distribute and monitor the delivered light intensity using the 2D histogram function. New since release 168 is a much-improved coordinate break function that permits easier analysis of bent optical paths and tolerancing of angles and offsets, and an improved Map display capability, like last year's, but now with complete text file output. Also newly formulated are transmission gratings: uniformly ruled, varied-line-space, and HOE ruled in both surface and volume phase holographic (VPH) technology.
