The article demonstrating how to use an OFH correct for aberrations introduces these operands, but neglects to tell you where they come from or how they're used. When you select Add Hologram Variables, you get an entry for every item in the accompanying 2 files that has been made a variable. Note the entry File # that tells you which hologram file the variable is from: The list will include the same # of variables from both models. If the number of variables is not the same, the excess will be populated with 0s and unchangeable. In the following example, construction file _1 has one more variable than construction file _1, and so variable #3 is a 0 with no V indicator, and modifying it does nothing to the construction model. Frustratingly, they don't tell you where the Variable # comes from. It is located in the respective construction files under Prescription Data. Scroll to SOLVE AND VARIABLE DATA. The variables are listed in order and s
Hi, I've been given a Zemax model that uses MIL number glasses to characterize the refractive index of several materials. For example, one material is 377571. The Zemax documentation states that: 'OpticStudio uses a formula for computing the index at each defined wavelength based upon the index and Abbe number defined by the MIL number. The formula is based upon a least squares fit of coefficient data of many typical glasses.' I would like to be able to plot this dispersion profile and be able to assess what refractive index is being computed for a range of wavelengths. Is there any feature of Zemax that allows computing this dispersion curve, or could I do it myself using another software program (Matlab, Python)? In addition, it seems that since Zemax also relies on 'many typical glasses', I'm also concerned about how these values could differ depending on the glass catalogs used for the specific computer, the version of Zemax, or other related factors. How are
