CODE V 10.1 - the newest release of optical design software from Optical Research Associates

Delivers Powerful, Efficient Diffraction Analysis Capabilities and Ease of Use.

CODE V 10.1, the newest release of the premier optical design software from Optical Research Associates, delivers powerful tools that increase the accuracy and ease of use of the program's diffraction analysis capabilities.

CODE V's Beam Synthesis Propagation (BSP), interface. In addition, BSP's groundbreaking Pre-Analysavailable in beta form in the previous CODE V release, has already proven to be a widely applicable general diffraction beam propagation analysis tool that can deliver high-accuracy results with unprecedented efficiency, saving the designer countless hours of system validation. CODE V 10.1 brings the first formal release of BSP and expands it in several important ways, with BSP now fully integrated in the software's graphical user is feature will recommend appropriate analysis controls based on the resident lens system, a feature unique to CODE V.

While Pre-Analysis makes BSP easy to use with minimal input, experts in beam propagation will have the flexibility to control virtually every aspect of the BSP process. A BSP beamlet footprint diagnostic graphic is new in 10.1, and provides the designer with a simple, visual way to assess the size and orientation of BSP beamlets on any surface in the optical system. Also, fiber coupling efficiency analysis has been expanded to include vector field data from BSP.

This release features new capabilities for modeling real-world effects of mid-spatial-frequency surface errors on an optical surface. Such errors are typically encountered on surfaces fabricated using diamond turning or high-end polishing methods. Now the designer can describe component surface errors by specifying the parameters of a power spectral density (PSD). BSP is used to predict the diffracted image degradation due to the mid-spatial-frequency surface errors.

CODE V 10.1 further enhances the program's powerful automatic optimization feature with an alternative method of calculating variable change increments, which can improve both the speed and quality of the optimization convergence. This new approach particularly benefits systems where the merit function is not strongly related to wavefront errors or surface sag, such as those involving a user-defined merit function or complex constraints.

CODE V 10.1 will begin shipping in July 2009.
