CODE V10 Optical Research Associates

CODE V®, the premier optical design software from Optical Research Associates (ORA®), now delivers faster optimization of complex optical systems by taking full advantage of parallel processing on multi-core architecture CPUs. In particular, both of its world-class local and global optimization routines in the release of CODE V 10.0, which are widely recognized as yielding superior results, are now enabled for multi-core operation. Optical designers can solve the most complex lens design problems in a fraction of the time needed using a single processor.

CODE V 10.0 also offers improved accuracy and ease of use for diffraction analysis. Its new Beam Synthesis PropagationÔ (BSP) feature uses a beamlet-based, diffraction propagation algorithm to include diffraction effects through the entire optical system design. BSP delivers greater accuracy than using exit-pupil diffraction computations, or beam propagation based on FFT or angular spectrum methods. Systems with astigmatic beams, polarized input optical fields, low f-numbers (e.g., microlithography lenses), or non-contiguous pupils are accurately analyzed with BSP. The feature is also useful for near-field diffraction analysis and for optical systems where the amplitude or phase is modified near the focus, such as with a grating, phase plate, or spatial filter. Determining appropriate inputs for any beam propagation algorithm can be challenging, but BSP solves this by including a unique pre-analysis feature, which automatically provides appropriate input recommendations for your specific lens system, including input field sampling, resampling and output grid characteristics. Using pre-analysis, BSP will also estimate an execution run time for your lens system.
