An Overview of CODE V version 10.2

The latest CODE V update, version 10.2, was released earlier this month. This major update to CODE V includes several enhancements:

Improved Method for Locating Ray-Surface Intersection: The method for determining the correct ray-surface intersection has been improved in CODE V 10.2. In earlier versions, CODE V’s efficient ray tracing algorithm could sometimes find the wrong intersection for systems with strong aspheres or for very wide angle systems. This would sometimes require the user to change the surface type so that a more robust but less efficient ray tracing algorithm was used. In CODE V 10.2, a new methodology to determine the correct surface intersection has been added that offers increased robustness without losing ray tracing speed. A 7 minute video of this feature is available.

CODE V 10.2 Feature Improvements: Several enhancements have been made to CODE V analysis, diagnostic, optimization, and tolerancing features, including:

Improved Handling of Real Image Heights During Optimization: The handling of real image heights during optimization has been improved for more efficient convergence.
Lens View (VIE) Enhancements: Improved surface range defaults have been implemented in the Lens View (VIE) option for finite conjugate and wide angle systems when drawing rays from the object surface.

New Performance Metrics for User-Defined Tolerancing: New performance metrics have been added to the Monte Carlo and Finite Difference user-defined tolerancing features. Users can now perform tolerance analysis using Strehl ratio, MTF, lateral color, Zernike coefficients, or chief ray angle of incidence as a performance criteria.
Support of Additional Graphics Formats: CODE V graphics files can now be converted to several additional graphics types including BMP, GIF, JPEG, PNG and TIFF.
Improved Transmission Analysis Output: The Transmission Analysis (TRA) output has been improved to more clearly show the transmission impact due to Fresnel loss, absorption, diffraction efficiency, and filter interferograms.

A 10 minute video overview of these and other enhancements to CODE V’s technical features is available

CODE V 10.2 Usability Improvements: Several usability improvements have been added to CODE V including:

Support of the Insert and Delete keys to insert/delete surfaces in the Lens Data Manager.
The Page Up/Page Down keys can be used for scrolling through text displayed in tabbed output windows.
The ability to include surface labels in the real ray (RSI/SIN) output.
A new Systems Setting dialog for entering the lens title, units, and aperture type has been added to the New Lens Wizard.

The image and object numerical aperture (NA, NAO), CODE V version number (CVV), and current error function value (ERF) can now be displayed in the status bar. In addition, the number of items that can be displayed has increased with four rows of data supported.

A 7 minute video overview of these and other usability enhancements in CODE V 10.2 are available

Updates to the Customer Support Web Site

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

The December issue of CODE V Enews, which features a tip on using finite difference derivative increments during optimization, has been added under CODE V Enews & Tips.

A link to download CODE V 10.2 is available on the Welcome page. The CODE V 10.2 Release Notes are available under Release Notes.
An updated copy of the zemaxtocv macro, used to convert Zemax lens data to CODE V lens data format, is available under Macros and User-Defined Features > Updated CODE V Sample Macros. This update includes support of real image heights.
