Quick Tip – Choosing the Best CODE V Algorithm for Your Design

CODE V is an extremely comprehensive optical design tool that includes analysis features for a wide range of optical systems, covering the design process from initial concept through fabrication and alignment.  The optical design process is supported by CODE V's nearly 50 main analysis features, with multiple calculation options within each feature.  Many analysis features calculate the same performance measure as others.  For example an MTF calculation is performed in the MTF option (geometric or diffraction based), the Ray-based MTF Tolerancing option (TOR), and by the MTF_1FLD and other macro functions.  In some cases, a user may see slight differences in the performance measure when comparing the results from one analysis feature to another.  These differences can occur due to different algorithms being used, differences in sampling techniques, or different effects being considered in the calculation (i.e., paraxial vs. diffraction based).   While most often these differences lead to only slight variations in the results of one type of analysis vs. another, in some cases the differences may be large enough to merit investigation (or an email to ORA Technical Support!).

To help users understand why these differences might occur and to assist in determining which algorithm is best suited for a particular application, the ORA Technical Support Staff developed a presentation for the 2006 CODE V Users Group meeting.  This presentation, Choosing the Best CODE V Algorithm for Your Design, is available for download from ORA's customer area of the web (www.oraservice.com) under CODE V Support > User Group Presentations.
