This is a very useful feature when specific values need to be monitored during the tolerance process. If a user script had been used, we could have reported any desired merit function operand values directly in the tolerance report. Incorrect lateral sag at the control points.The optimized system consists of an OSRAM LED and a freeform lightpipe that has been optimized to achieve maximum power and collimation at the detector. When tolerancing multi-configuration systems, the merit function used must account for each configuration using multiple CONF operands.Īs an example, we will use the optimized freeform-z lightpipe. Sequential ray tracing is computationally fast and is extremely useful for the design, optimization, tolerancing, and analysis of such systems.You may have noticed that this is the case in the Merit Function when using NSDD. When working exclusively in Non-Sequential Mode, the surface number will always be 1. 1st question is impact of detector settings for optimization (I use rectangular detector). I have red articles on Zemax page (idea shown in image starting point was optimized as imaging system in sequential mode). Tolerance settings that have no meaning in non-sequential systems (ray aiming, separate fields/configs, etc.) are disabled. The NSDD operand in the ZPL does perform similarly to the NSDD optimization operand, but in the case of the ZPL, we are required to specify a surface number. 1 reply I would like to optimize a 2 lens illumination system for 'high' efficiency and 'high' homogeneity.Make sure the merit functions loaded by the script don’t contain TOLR operands themselves. Orthogonal Descent (OD) optimization uses an. TOLR is supported during optimization in Non-Sequential Mode, however user script is the only valid criteria selecting merit function as the criteria would lead to an infinite loop. For a detailed description of NSDD capabilities, see the Optimization chapter in the ZEMAX users guide.As an example, a free-form mirror is optimized to maximize the brightness of an LED from 23 Cd to >250 Cd in just. The methods are to use Pixel Interpolation, aggregate detector data (moment of illumination data) and the orthogonal descent optimizer. Use merit function boundary operands (NPGT, NPLT, etc.) to constrain compensator values. This blog provides a recommended approach to the optimization of non-sequential optical systems. Compensator min/max bounds are always ignored because merit function and user script are the only available criteria. CO6Design of optical systems based on off-the-shelf components with Zemax Optical aberrations, optical aberrations associated with off-the-shelf components.Through the API, applications may either communicate directly with opened instances of OpticStudio or run OpticStudio as a background process. The API allows users to write applications built on either COM (C++) or. Here are some additional points to note about non-sequential tolerancing: ZOS-API.NET provides a powerful means of communicating with and/or customizing OpticStudio. Tolerancing is the process by which errors (manufacturing, assembly, material, etc.) are systematically introduced to an optical system in order to determine their effect on system performance.
