RayCAD Version 8.0
Oct 2007
RayCADRequest Info
TYNGSBORO, Mass., Oct. 22, 2007 -- RayCAD Inc. has launched RayCAD version 8.0 of its optical modeling software which features exact optical ray tracing, 3-D interactive optical modeling within AutoCAD and Mechanical Desktop.

RayCAD enables fine-tuning of optical and mechanical designs; it provides a platform with which to study ray intersections and adjust surface parameters like location, direction and surface curvature for instantaneous feedback in the form of ray trace, spot diagrams and RMS (root mean square) spot size.

Since the light path is clearly shown in a drawing, RayCAD users can precisely design surrounding mechanics and baffling -- right down to adjustments or allowances of optical component tolerances, reducing tedious prototype modifications.

The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
ray tracing
The mathematical calculation of the path traveled by a ray through an optical component or system.
