Models are created by importing lens design or Computer Aided Drafting (CAD) files or by directly creating the solid geometry in TracePro. Users can define, position, move, rotate, scale, sweep, and revolve objects and surfaces via the user friendly 3-D CAD interface and with special tools to insert optical elements such as lens elements, Fresnel lenses, tubes (lens barrels) and baffles.
The 3-D model can be zoomed, panned, rotated and rendered.
Material and Surface Properties
Material and surface properties are applied to object and surfaces in the solid model. Types of properties include:
Thin film stacks
Temperature and Temperature Distribution
RepTile™ – surfaces with random or periodic arrays of repeated structures
Surface light sources
Blackbody / Gray body
Users may define properties or apply from TracePro’s property catalogs of commonly used and commercially available materials and coatings:
Optical thin films – anti-reflection, metals, dielectrics, dichroics and interference filters
Surface finishes – anodizing, mechanical textured, diffusing and absorbing paints
Gradient index materials
Wire grid polarizers
New and updated properties are continuously being released and made available to users with Maintenance and Support Subscriptions
Raytracing is the means by which TracePro simulates the distribution of flux throughout a model or at selected surfaces.
There are three methods of defining rays that launch into the model for ray trace – Grid, Surface, and File sources. Sources are summarized in the Source Tab of the System Tree as shown below. Here they be disabled, traced, or you can open a dialog box to edit a source.
