CODE V Tip – Additional Performance Metrics Available for Finite Difference and Monte Carlo Tolerancing

CODE V offers a variety of methods for predicting as-built performance through use of its fast wavefront-differential tolerancing feature (TOR), as well as via finite difference (TOLFDIF) and Monte Carlo (TOLMONTE) tolerancing methods.  For a detailed summary of these methods, including the pros and cons of each, a white paper titled CODE V Tolerancing: A Key to Product Cost Reduction is available for download from ORA's Customer Service Web site, www.oraservice.com, under CODE V Support > Technical Papers.

CODE V's fast wavefront-differential tolerancing feature (TOR) supports several built-in tolerance metrics, such as MTF, RMS wavefront error, fiber coupling efficiency, polarization dependent loss, and Zernike wavefront coefficients.  If you wish to tolerance your lens system using an alternate performance metric, CODE V's finite difference (TOLFDIF) or Monte Carlo (TOLMONTE) tolerancing, both under Analysis > Tolerancing, can be used.  Two additional built-in performance metrics, RMS Spot Size and Encircled Diffraction Energy, are available when using either of these alternate tolerancing methods.  In addition, both methods support a user-defined mode where any performance metric that you can compute in CODE V can be used as a tolerance criteria.  The user-defined mode requires a macro be written to compute the alternate performance metric which passes this data back to TOLFDIF or TOLMONTE.   Performance metric macros RMS Spot Size and Encircled Energy are supplied with CODE V and can be used as starting points for writing these user-define tolerance metric macros.  For complete details, please refer to the CODE V Reference Manual, beginning on page 20-107.

CODE V's Technical Support Team has written several new performance metric macros that can be used with TOLFDIF or TOLMONTE.  These macros are currently available for download from the Customer Service Web site, www.oraservice.com, under CODE V Support > Macro and User-defined Feature Downloads > Macros from ORA Tech Support.  The new performance metric macros include:

• TOLSTREHL.SEQ: Uses Strehl ratio as a performance metric  
• TOLTELECTENRIC.SEQ: Uses telecentricity as a performance metric
• TOLLATCOLOR.SEQ: Uses lateral color as a performance metric
  
• TOLZERNIKE.SEQ: Uses Zernike coefficients as a performance metric
  
• TOLMTF.SEQ: Uses MTF as a performance metric

While MTF and Zernike coefficient tolerancing can be performed using CODE V's fast wavefront-differential tolerancing (TOR), these last two macros, TOLZERNIKE.SEQ and TOLMTF.SEQ, are now available for use when performing finite difference or Monte Carlo tolerancing.

2008 CODE V User Group Meeting Presentations

The annual CODE V User Group Meetings were held last month in Pasadena, Santa Clara, and Rochester.  Thank you to all who participated in this year's events.  If you were not able to attend, copies of some of the presentations from these events are available on ORA's Customer Service Web site, www.oraservice.com, under CODE V Support > User Group Presentations, including:

• Advanced Optimization Techniques
  
• CODE V Tips and Tricks (from Tech Support)
  
• Ghost Image Simulation with IMS and Other CODE V Tools
  
• ORA Engineering: Consumer Personal Display Prototype

Updates to ORA's Customer Service Web Site

In addition to the new tolerancing macros and User Group presentations described above, the following additions have been recently made to ORA's Customer Service area of the web,www.oraservice.com, under CODE V Support:

• The June issue of CODE V Enews, which featured an overview of CODE V 9.82, has been added under CODE V Enews & Tips.
  
  
• A recorded demonstration of the new features in CODE V 9.82 is available for viewing under Webinar Recordings & Demos.
  
  
• A new FAQ on customizing CODE V graphics for reports and presentations is available under Tech Support FAQs > Graphics FAQs.
  
  
• An updated version of the CODE V Plot Viewer, which can be used to view CODE V graphics on PCs where CODE V is not installed, is available for download under Tech Support FAQs > Graphics FAQs.
  
  
• An updated version of newglassprv.seq that include data for Hoya E-FL6 has been added under Macro and User-defined Feature Downloads > Updated Macros.
