Singlets Achromats Laseroptics MV Lenses Zoom Optics Plano Optics Polarization Optics Mirrors TracePro: Features, Highlights, General Information TracePro®is a comprehensive, versatile software tool for modeling the propagation of light in imaging and non-imaging opto-mechanical systems. Models are created by importing from a lens design program or a Computer Aided Drafting (CAD) program or by directly creating the solid geometry in TracePro. Source rays propagate through the model with portions of the flux of each ray allocated for absorption, specular reflection and transmission, fluorescence and scatter. From the model and ray trace, analyze: •• Light distributions in illumination and imaging systems •• Stray light, scattered light and aperture diffraction •• Throughput, loss, or system transmittance •• Flux or power absorbed by surfaces and bulk media •• Light scattering in biological tissue •• Polarization effects •• Fluorescence effects •• Birefringence effects TracePro features a simple, intuitive interface and short learning curve that is both powerful and user-friendly for engineers and scientists of all disciplines. Three editions of TracePro are available to most cost effectively accommodate design needs. Node locked and floating network licenses are available for use on a single computer with a USB hardware key and on a network respectively. A three month Maintenance and Support Subscription is included with all licenses. Solid Modeling 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: •• Material •• Refraction •• Fresnel reflections •• Bulk absorption •• Bulk scatter •• Gradient index •• Birefringence •• Surface •• Reflection •• Coatings •• Thin film stacks •• Scatter •• Surface absorption •• Gratings •• Temperature and Temperature Distribution •• Polarization •• Fluorescence •• Diffraction •• RepTile- surfaces with random or periodic arrays of repeated structures •• Surface light sources •• Flux •• Irradiance •• Blackbody / Gray body Users may define properties or apply from TracePro’s property catalogs of commonly used and commercially available materials and coatings: •• Optical glasses •• Optical thin films - anti-reflection, metals, dielectrics, dichroics and interference filters •• Plastics •• 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. Raytrace Raytracing is the means that TracePro simulates the distribution of flux throughout a model or at selected surfaces. Sources There are three methods of defining rays that launch into the model for ray trace – Grid, Surface and File sources. For a Grid Source, the user specifies: •• Spatial beam profile and weighting – uniform, Gaussian •• Spatial Gaussian beam dimensions – x,y waists at 1/e 2 radius •• Angular beam profile and weighting – uniform, Gaussian, Lambertian, Solar •• Angular beam dimensions •• Beam orientation •• Polarization state •• Degree of polarization A Surface Source emits rays in a defined angular distribution from one or more surfaces of a solid object. The user specifies the source type as Flux, Irradiance, Blackbody or Graybody. A File Source contains ray data and can be inserted into a TracePro model. Data consists of XYZ starting points for each ray, XYZ direction vectors for each ray, and a flux. A File Source enables: •• Incorporation of actual measured source distribution data from Radiant Imaging into the TracePro model •• Creation of a source from theoretical or measured data from another software application Ray Tracing There are user-specified options available in TracePro Standard and Export editions that can enhance speed and/or accuracy to the raytrace: •• Importance Sampling •• Ray Splitting •• Exact Raytracing •• Accelerated Raytracing •• Facetted Raytracing •• Simulation Mode •• Multiple Exit Surfaces (Simulation Mode) •• Voxelization in Object Space •• Aperture Diffraction 596 US-Phone +1 585 223-2370 UK-Phone +44 2380 744 500
Optics Software Analyze TracePro’s Analysis menu provides a comprehensive set of tools to view and analyze the results of the raytrace. Irradiance and Illuminance Maps An Irradiance Map shows irradiance incident or absorbed on a selected surface. Map types include the quantities to plot: •• Irradiance, a plot of power in watts per unit area or lux, incident or absorbed by a surface •• CIE (x,y) and CIE (u1,v1), plots of color in CIE coordinates •• Bitmap RGB and True Color Display Options control the plot output. The results of an irradiance calculation can be exported to other software packages such as Excel and the data and plot may be saved as text and bitmap files. Luminance/Radiance Maps After a Luminance Map is raytraced, it may be displayed as true color or a photorealistic rendering based on the wavelengths traced. The results of the ray trace may be displayed as either a Luminance or Radiance Map with photometric units (cd/m 2 , foot-lambert, or millilambert) or radiometric units (W/ m 2 ) respectively. 3-D Irradiance Plots 3-D Irradiance Plots map the incident flux on selected surfaces or objects. Candela Plots Polarization Maps Polarization Maps map the polarization ellipse for the incident flux on the selected surface. Color levels graphically display the degree of polarization at points on the surface. Incident Ray Tables An Incident Ray Table shows data for rays incident on a selected surface. Ray Sorting Ray Sorting affects the display of rays in the model window and may be applied to plots and tables. The display of rays may be sorted by: •• All rays •• Only rays hitting a selected surface •• Only specular and no scattered rays •• Only rays undergoing a single or undergoing multiple scatter •• Wavelength •• % of starting rays Reports TracePro generates raytrace and property reports. The Flux Report provides a summary of surface area, number of incident rays, incident and absorbed fluxes and lost flux. Data is displayed for bulk absorption and incident flux for each object. The Property Data Report contains the model’s property data and may be exported to a *.txt file. The Raytrace Report displays physical and virtual memory usage and elapsed raytrace time. Design, Macro Language TracePro includes the Scheme programming language, a powerful and flexible macro language for manipulating views, editing geometry and writing macro programs. TracePro’s Macro Recorder captures the TracePro commands used during a session and stores the equivalent Scheme commands to a file. The file can then be executed. TracePro Applications •• Life Sciences •• Industrial Manufacturing •• Metrology •• Inspection •• Material Processing •• Machine Vision •• Process Control •• Automation and Robotics •• Semiconductor Processing and Metrology •• Information Technology •• Data and Telecommunications •• Data Storage •• Supply Chain: Bar Code and RFID •• Printing and Reprographics •• Scanning •• Imaging •• Aerospace •• Aviation •• Astronomy •• Defense •• Environmental Monitoring and Sensing •• Remote Sensing and LIDAR •• Security •• Power and Energy: Laser Fusion •• Stray Light Analysis Candela Plots plot luminous intensity or flux per solid angle. These intensity plots are displayed in photometric units (candelas or lumens per steradian) and in radiometric units (watts per steradian). Irradiance/Illuminance Viewer The Irradiance/Illuminance Viewer allows users to view Irradiance/Illuminance Maps that have been saved as text files and combine data from multiple maps.
