OSLO Rev. 5.4 Technical Data

OSLO is a comprehensive optical design program with the depth and features needed to develop state-of-the-art optical products. OSLO achieves great flexibility through the combination of extensive optical design capability and a powerful language that allows you to merge new commands with the main program.

OSLO SIX is the flagship version of OSLO. Even complicated systems, such as those containing arrays of lenses or surfaces that have no symmetry, can be accommodated. Sophisticated evaluation routines are included for analyzing the effects of partial coherence in microlithography or vector diffraction effects in microscopy. Non-sequential ray tracing enables the design of systems containing complex prisms and non-imaging elements. OSLO SIX contains ASA, an advanced global optimization method, and the ability to design systems using eikonal functions.

OSLO PRO contains an especially strong optimization capability, with an internal error function generator that allows optimization to be carried out with the highest efficiency. OSLO PRO contains more than 4000 catalog and patent lenses, including the Optics Toolbox, Cox, and Warren Smith starting design libraries. You can import files from GENII PLUS and other design programs, as well as export drawing data to CAD software.

OSLO Light was developed for engineers in optics, lasers, and electro-optics who need to design optical systems or carry out optical evaluation on an occasional basis. OSLO Light is the lowest-cost full-featured program on the market today. It includes not only optimization and tolerancing, but also advanced Gaussian beam propagation, fiber-coupling calculations, and random ray tracing routines that can be used to analyze illumination systems.

Common features

The following table shows the principal features of each level of OSLO. Because of the large number of commands and the unique operation of OSLO, it is not possible to completely describe the program in tabular form. If you have questions about a specific capability, please contact Sinclair Optics.
