If you don't hold a Premium license but are interested in this, let us know, and we can put you in touch with your account manager to discuss how to get you access. The Bitmap Wizard is, however, available for Premium licenses only. In Zemax there is a merit function editor that includes different operands. It is a numerical value defined by the user and used to evaluate the deviation of an optical system performance relative to a series of design targets. Identify system sensitivities and predict manufacturing and assembly yields. Build merit functions to optimize system performance.

#ZEMAX MERIT FUNCTIONS SOFTWARE#
The software optimizes to obtain an optimal solution, but at this optimal position, the light spot on the image surface is not the smallest. When using Zemax to design and optimize an optical system, merit function is often used. It is our most popular training and assumes a background in optics but not necessarily with Zemax OpticStudio. In this case, it took six variables of the extended polynomial going out to the 27th term (They are X0Y2, X2Y0, X0Y4, X4Y0, X0Y6, X6Y0), but more complicated patterns will need more terms and possibly other surfaces. When I am optimizing a relay system, the optimization method uses the spot, and the variable is the thickness. This tool allows you to use a bitmap image target to shape the beam into, theoretically, as complex a pattern as you wish so long as you have enough of the right parameters to vary. The merit function, though, you can see is very long, and I built it using the Bitmap Optimization Wizard.

If you’re doing relatively simple stuff (say 5 elements or less, and a narrow spectral range) then Zemax is fine. For example, telecentricity and distortion. Only these can be used in optiSLang for further analysis. If you look at the cross sections in X and Y you can see that they are very good in terms of flatness and of a sharp drop at the edges.

CodeV also handles constraints much better in the merit function. Integration of VirtualLab 3 Zemax parametrization Define all outputs of the system in Merit Function Editor. It takes a circular beam from a Source Gaussian and reflects from an optimized Extended Polynomial to produce a good square distribution at a detector. Following up on this, I'm attaching an example similar to one we use in the Illumination and Stray Light course.
