RayCAD
Integration of optical and mechanical design based on AutoCAD

 

RayCAD for AutoCAD

The increase in optical applications and the diversity of optical design has changed the requirement of optical design software.  Today's engineer is not necessarily a specialist in optical design.  More and more, designers are finding the need to integrate optics and mechanics (and the ability to freely "kick around ideas" optically), in much the same way mechanical design tools such as AutoCAD works.  RayCAD for AutoCAD meets that need.

bullet Often optics have to conform to the limitations imposed by compact packaging.  RayCAD allows you to model optic and mechanical as one.  The optical design isn't off floating in space.  You get real visual input - see exactly how it all fits together.
bullet Automatically generate custom optical components. There's also a catalog of more than 650 Melles Griot lenses and Corning aspherics to be used as they are or modified to suit your needs.
bullet Sequential as well as non-sequential propagation from anywhere, in any direction. Multiple sources of any configuration can be precisely and easily modeled using nearly unlimited numbers of input rays.
bullet Input rays can be associated with several wavelengths. A selection of glass manufacturers are provided.  Also, custom index tables can be used.
bullet Ray intersections can be studied close up and viewed from any direction.  AutoCAD's Zoom, Dview and Orbit give great flexibility in evaluating a design.
bullet Optimization allows interactive moving and rotating components, changing curvatures, and immediately see the results. Automatic focusing and collimation is also provided.
bullet Spot diagrams let you analyze the image. The image can be projected onto any surface in the layout.
bullet If you are using ZEMAX, our interface allows import and export of optical data files.
bullet Use the Render-Ready feature with a rendering package to simulate transparency, diffusion, reflection and refraction of surface properties, and define shadows. The design is rendered, complete with rays traced, to create a photorealistic picture.
bullet Wavelength diffraction is easily accomplished using echelles, holographic and ruled gratings.
bullet The Adjust command provides an easy way to study ray intersections, adjusting surface parameters like location, direction and surface curvature while getting instantaneous feedback in the form of ray trace, spot diagrams and spot size expressed in RMS. It provides an excellent way to fine-tune your optical design.
bullet Even Aspheric using 8 coefficients.  The even aspheric surface uses the even powers of the radial distance to describe the asphericity.
bullet Odd Aspheric using 8 coefficients.  The odd aspheric uses even and odd powers of the radial distance to describe the asphericity. 
bullet Decentering of surfaces enables off axis surface generation.
bullet Scattering traces.  Each refractive surface will cast a new reflected ray.  This can be up to 5 branches deep.
bullet RMS  (Root Mean Square).  Value is computed when performing a Grid trace.
bullet Mirror Rotation takes into account the half angle due to reflection, so you can simply point to where the reflection needs to be and the mirror will rotate half of that angle.
bullet Gratings ind the appropriate order.  If wavelength falls outside the free spectrum, the appropriate order is found and used.  This enables you to trace wavelengths covering many orders.
bullet Save and load wave selection.  This is useful if a long list of wavelengths has been created.
bullet Use existent input rays.  You can change wavelengths and color association without gathering input rays each time.
bullet Automatic erasing of the last trace can be turned on, there by eliminating the "Erase last trace Y/N" prompt.
bullet Spot ID's are kept and will automatically erase between traces, just like rays.
bullet Random ray and random spot count can be controlled.
bullet Number of intersects per ray per surface can be limited to prevent endless TIR.

Compatible with AutoCAD version 2015.
