CODE V 9.82 Delivers Improved Spot Size Calculation and Display Capabilities

June 2008 - The latest version of CODE V delivers enhancements to the Geometric Spot Diagram feature which offer designers greater ease of use and efficiency. Specifically, CODE V 9.82 enables users to specify the desired accuracy level of the RMS spot computation, and the software then automatically determines the minimum ray grid necessary to achieve this precision. This is a more efficient method than that used by other software programs, which require users to set the ray grid density manually, and then iteratively increase this density until spot size precision stabilizes. Moreover, CODE V now uses separate ray grids for computation and graphing purposes to yield accurate spot size computations along with a less dense plotted ray density for optimal visualization of the spot structure.

The Spot Diagram graphical display also now supports various reference overlays (e.g., Airy disk and/or detectors) and annotations, which is useful for design reviews and presentations. Two new macro functions provide access to virtually all spot size data, greatly improving the user’s ability to perform customized analysis, optimization, and tolerancing.

In addition, this release contains several other smaller enhancements based on customer input, including:

• Enhancements that provide greater flexibility when using gradient-index lens materials within non-sequential surface ranges.
• The addition of several new sample files, including lenses, sample images for use with the 2D Image Simulation feature, and macros. For example, the new FISHEYE2 sample lenses illustrates system modeling issues for a lens with a hyper-hemispheric field of view.
• Performance improvements that speed up tolerancing on RMS spot diameter.
• Improvements to CODE V’s ray tracing processes that have resulted in a 50% ray trace speedup for optical systems in which polarization ray tracing is activated. This performance enhancement has been in place since the CODE V 9.81 release, but was not previously reported.

CODE V 9.82 will begin shipping in June 2008.  For more information, please send an email to info@opticalres.com.
