Welcome to Stellar Software, a leading provider of optical ray tracers catering to engineering and education communities since 1985. Our flagship product, BEAM FOUR JAVA EDITION, offers comprehensive ray tracing solutions for optical professionals, students, and teachers. Embracing open source policies since 2015, we now offer BEAM FOUR for free worldwide. This gesture is a token of gratitude for the years of support from the community.

BEAM FOUR provides diverse features, including multiple on-screen layouts, maps displaying image quality variations, and Gaussian scattering surfaces. The source code and documentation are available on GitHub, further enhancing transparency.

Our user-friendly software handles optical systems with precision, like Czerny-Turner spectrometers and Cassegrain telescopes. The advent of Java as a cross-platform language allows us to deliver our high-value application globally.

Our products include lenses, mirrors, prisms, diffraction gratings, and more. We also provide detailed guides and example files. To run BEAM FOUR JAVA EDITION, ensure Java 1.8.0 or higher is installed on your computer.
