Quick Tips – Focus on Field Map Analysis (FMA) in CODE V

CODE V’s Field Map (FMA) analysis produces 2-D plots of various field-dependent parameters including distortion, astigmatism, coma, RMS spot diameter, RMS wavefront error, and Zernike wavefront polynomial coefficients.  It can also be used to calculate Bragg diffraction efficiency over field for systems that include volume HOEs.

Below is a Field Map plot representing RMS wavefront error as a function of field.

CODE V’s Field Map analysis can be particularly handy when working with asymmetric optical systems where it can be used to assess field dependence of aberrations.  This is analogous to the use of a transverse aberration (RIM) plot for a symmetric system.

A training video on using FMA has been added to ORA’s Customer Support Web site, www.oraservice.com.  This 30 minute video provides an overview of FMA and a demonstration of its use.  The demonstration shows how to use FMA to identify which Zernike coefficients to constrain during optimization in order to minimize coma across the field of view for a three-mirror anastigmat.   If you design asymmetric systems, we think you’ll find this video useful.

CODE V User Group Meeting Presentation

The 2009 CODE V User Group meetings were held last month in Pasadena, San Jose, and Rochester.  Thanks to all of you who participated in these meetings and for your positive feedback.  For those unable to attend, we have placed copies of presentations from these meetings on ORA’s Customer Support Web site, www.oraservice.com.   These presentations can be found under CODE V Support > User Group Meeting Presentations and include the following topics:

• Optimization Troubleshooting
• User-defined Features in CODE V
• Modeling Segmented Mirrors with Non-Sequential Surfaces
• ORA Engineering: Tolerancing Real Gaussian Beams with M²
  

Updates to the Customer Support Web Site

The following updates have been made to the ORA Customer Support Web site, www.oraservice.com, under CODE V Support:

• The June issue of CODE V Enews, featuring a tip on transferring your CODE V GUI settings after an update has been added under CODE V Enews & Tips.  You may find this useful when CODE V 10.1 ships later this month.
• The 2009 CODE V User Group Presentations listed above have been added under User Group Presentations.
• A new video on CODE V’s Field Map (FMA) analysis has been added under Demo & Training Videos.
