![]() The first step to fixing this error is to repair the ZLM using the instructions outlined here. You must ensure that the version of the ZLM installed on both computers either predates or postdates August There was a change made to the transfer process at this time, and softkey licenses cannot be transferred to or from ZLMs which use different transfer methods. The first thing to check which version of the ZLM is installed on both the source and destination computers. When softkey licenses fail to transfer from one computer to another, they often do so for one of two reasons: the Zemax License Manager ZLM on one computer is outdated or one or more components of the Zemax License Manager are installed improperly. ![]() ![]() Check out this webinar for a detailed discussion on how and when and when not to use POP to model Gaussian beams in OpticStudio. These three factors can all contribute to difference between a POP results and ray-based analysis results. Near the Rayleigh range, however, the beam size will change nonlinearly with propagation distance. This is not the case for a Gaussian beam, as it will diffract as propagates. That is, a collimated beam will never change size and a diverging beam will retain the same divergence everywhere. Namely, POP models a different type of propagation from traditional ray propagation in that it is most commonly used to model Gaussian beams. The results reported by Physical Optics Propagation POP may differ from those reported by ray-based analyses, such as the Spot Diagram, for several reasons. TrueFreeForm in OpticStudio enables a unique non-parameterized optimization methodology for optical design. Using the TrueFreeForm surface for grid based freeform optimization.
