Mobile devices such as smartphones, e-readers, and watches are becoming ubiquitous in today’s world. Precise optical engineering is required to optimize the performance of mobile features such as the camera system, sensors, and the display. A key design objective for a mobile display is uniform...
Read MoreFRED allows for simulation of physical optics phenomena such as diffraction and interference. With this capability, components such as Gaussian laser beams and interferometers can be accurately modeled and incorporated into optical systems. A full description of this application example can be found here: Newton’s Rings...
Read MoreThe attached FRED example demonstrates how to optimize the inter-lens spacing of a Galilean beam reducer using geometric ray collimation as the optimization metric. Open the model and expand out the Geometry folder and the Collimator subassembly node. Observe that there are three geometry elements...
Read MoreFRED Optimum supports multiple configurations within a single FRED document using the configuration editor interface found in the FRED menu, Optimize > System Configurations. The configuration editor dialog allows for the definition of multiple configuration variables as well as a mechanism for setting the current...
Read MoreThere is a feature in FRED called “User Tools” which enables you to link your custom scripts to buttons on software’s main toolbar. Thus, by simply pressing the corresponding toolbar button you will be able to run your custom script tool. This article goes through the...
Read MoreFRED’s toolbars and windows can be floated or docked anywhere on your screen and while this makes customization of the GUI layout quite flexible, it has resulted in reports of “lost” toolbars and menus. If restoration of any lost toolbars and windows (ex. output window) cannot be...
Read MoreThe purpose of this article is to describe two scripts which work together to demonstrate how to plot multiple data series in a custom FRED chart. The FRED file associated with this document contains two embedded scripts: chartLibraryExampleMaster – This script generates a user-specified number of Gaussian profiles...
Read MoreWhen FRED is installed on a computer for the first time, the default preference settings will not be optimized to leverage the resources available on the machine. Rather, the default preference settings are deliberately chosen for program stability. This knowledge base article discusses the various...
Read MoreRPC Photonics has high quality BSDF measurement data available for their engineered diffuser products and it turns out that with a little help the data is essentially already prepared for use in FRED. The steps below describe how to use the attached FRED script to...
Read MoreAs of version 14.40 there is no script command equivalent to the directions spot diagram analysis available in the GUI. This knowledge base article details a script utility which manually performs the equivalent directions spot diagram analysis in the scripting language. Download the PDF: Direction-Spot-Diagram-Statistics.pdf Download the FRED...
