The latest version of Code V, the optical design software from Optical Research Associates (ORA), delivers enhancements to the Geometric Spot Diagram feature, which offers 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 stabilises. 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 visualisation 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 customised analysis, optimisation, and tolerancing.
In addition, this release contains several other smaller enhancements based on customer input. These include enhancements when using gradient-index lens materials within non-sequential surface ranges and the addition of several new sample files (e.g., lenses, images, and macros).
