8/30/2023 0 Comments Zemax non sequential optimization![]() ![]() This number is maximized by minimizing the inverse with RECI. Pixel number -3 corresponds to the ray count on the detector. ![]() After the ray trace detector data can be retrieved with NSDD. After that, a ray trace is performed with NSTR. ![]() Through ray tracing and non-sequential analysis, Zemax accurately. In the merit function, first the detector is reset to zero by operand NSDD with all parameters set to zero. The software also offers optimization tools to improve system performance based on. What is the overall efficiency of the illumination system now? Solution: a) System: A radius of 20 mm is used for R as initial value. Optimize the lens shape to get the best efficiency on the detector, if this is now at a location z=150 mm. The shape of the mirror is now fixed with a radius of curvature of 20 mm. CO6Design of optical systems based on off-the-shelf components with Zemax Optical aberrations, optical aberrations associated with off-the-shelf components. The diameter is 80 mm, the thickness 20 mm and the material BK7. b) Now an aspheric lens is located in front of the mirror. Using the TrueFreeForm surface for grid based freeform optimization. Now increase the detector distance to 500 mm and optimize again. Video - Optimization - Illumination System Design. Optimize the curvature of the paraboloid for the best efficiency of light detection under these conditions. For example, in a typical imaging system design, optimizing for best RMS spot, I have a design with a starting MF of 0.02 with 12 variables, all thicknesses and. A rectangular detector with size 10 mm x 10 mm is established in a distance 200 mm. I was pleased to see the new optimization routines in 21.1, but I have not yet succeeded in getting a better result (either in MF value or speed) with them than with the DLS optimizer. Orthogonal Descent (OD) optimization uses an. But if you look in the help system for the merit function editor you will find a category 'Constraints on Non-sequential Object Data.'. The radial aperture is selected to be 40 mm. For a detailed description of NSDD capabilities, see the Optimization chapter in the ZEMAX users guide. Hi Christy, There is no entry for this in the wizard, probably because the parameters for non-sequential objects are so inconsistent. This blog post gives a recommended approach to the optimization of non-sequential optical systems. A parabolic reflector is located 10 mm to the left of the source center. This applies anywhere these algorithms are used such as in Hammer optimization, Global optimization and tolerancing. Herbert Gross Uwe Lippmann, Yi Zhong, Dennis Ochse Friedrich Schiller University Jena Institute of Applied Physics Albert-Einstein-Str 15 07745 Jena Exercise Solutions 15: Optical Design with Zemax for PhD - Advanced Exercise 15-1: Illumination system with non-sequential raytrace a) In non-sequential mode, define an ellipsoidal volume source with dimensions of diameters 1 mm in x and y and 2 mm in z-direction. DLS is generally recommended, but for systems where the solution space is quite noisy, like illumination design or other non-sequential systems, the OD algorithm will likely outperform the DLS optimizer. ![]()
