FRED User Interface

FRED's powerful CAD interface allows the user to build logically and physically related models with the power and usability of a commercial CAD program.

In fact, using FRED's CAD interface is often the best choice as many commercial CAD programs do not describe surfaces with the detail required to give a true result for optical scattering. FRED was designed from the ground up to provide superb visualization of opto-mechanical systems.

Camera Design

All aspects of component visualization are under the complete control of the user. With little effort the user can create photorealistic representations of their systems – which have been shown repeatedly to add credibility and clearer understanding to client briefings during product development.

Large Synoptic Survey TelescopeAdditionally FRED can incorporate the results of irradiance, intensity, and color image calculations directly into the rendered view, and offers users cutaway views and anamorphic scaling.

The combination of the tree control (CAD-like) interface and real time visualization allows the user to quickly construct, analyze, and edit the FRED model with confidence. Inexperienced and infrequent users quickly gain confidence in their modeling and analysis efforts because they can see exactly what is going on at all times. Experienced users can quickly navigate the user interface to develop a true understanding of the light propagation characteristics of their system while at the same time producing powerful graphics that communicate concepts to their peers.

No other optical engineering software combines power and ease-of-use like FRED.

CAD Import/Export

Diode LaserEven though FRED has a sophisticated CAD interface CAD models can be imported and exported using both the Initial Graphics Exchange Specification (IGES) and STEP AP203 and 214 formats and can be shown in either wireframe or solid model views.

CAD geometry is imported as a set of Non-uniform rational B-splines (NURBS) and represented as curves and surfaces. FRED automatically takes these curves and surfaces and groups them into subassemblies.

After import it is also possible to position, trim, or modify the imported geometry in the same manner as any natively created geometry.

FRED exports both the opto-mechanical subassemblies and a full ray set detailing the footprint of the optical ray set or beams through the optical assembly. This feature is perfect for checking ray set or beam impingement on mechanical structure through the optical path.
