Optonom Scientific Instruments Ltd.Co. has been signed distributorship agreement in 2017 and the company is the unique distributor of TracePro, OSLO, RayViz in Turkey.

TracePro® is an award-winning opto-mechanical design software used for designing and analyzing illumination and optical systems.
Illumination Design, Stray Light Analysis and Optimization Software streamlines the prototype to manufacturing process for illumination systems with a familiar CAD interface, 3D optimization, extensive model library, and seamless interoperability with popular CAD systems. TracePro offers users a sophisticated and powerful optical design environment combined with a short learning curve to accelerate product time-to-market.

TracePro models are created by importing lens design or CAD files, as well as by directly creating the solid geometry within TracePro. Models can be modified by using move, rotate, scale, sweep, and revolve object and surface operations via the user-friendly, 3D CAD interface. Primitive solids, such as tubes, blocks, cones, and spheres; and optical elements, including lens elements, reflectors, and Fresnel lenses, can also be inserted.

TracePro utilities allow interactive sketching to quickly enter 2D and 3D profiles; and then extrude, revolve, and combine these surfaces to create sophisticated geometry, like lightpipes, reflectors, and free-form optics. Visualization options include: photorealistic rendering, solid rendering, silhouette, wireframe, and hidden line views. Users also have the ability to pan, rotate, zoom, and perform other standard geometry manipulation techniques. TracePro’s multiple document, multiple view architecture allows you to have several views of the same model open at the same time, and several models open at the same time. Copying and pasting objects from one model to another requires just a couple of keystrokes or menu picks.

Refarences of TracePro in Turkey
The companies which use various editions of TracePro, OSLO and RayViz are EAE Aydınlatma A.Ş., Arçelik Eskişehir Buzdolabı İşletmeleri A.Ş., PSL Elektronik Sanayi ve Ticaret A.Ş., Heper Group Moonlight, Mavili Elektronik Tic San A.S., VSY Biyotechnology ve Ilaç San. A.Ş., Eczacibasi Yapı Gerecleri San. ve Tic A.Ş., Selex ES Elektronik Turkey Anonim Şirketi. Some academicians and graduate students who work at the optical research departments of Akdeniz University, Dokuz Eylül University, İzmir Institut of Technology and İzmir Katip Çelebi University realize their designs with TracePro, OSLO or RayViz.

Optical Properties
A wide range of material and surface properties can be applied to objects and surfaces in the model. Optical properties that can be specified include: • Material properties – index of refraction, absorption coefficient, and birefringence • Aperture diffraction • Surface properties – reflectance and transmittance coefficients, surface absorption, surface scatter • Bulk scatter • Fluorescence • Gradient index • Mueller Matrix for polarization modeling • Surface source • Temperature distribution • Thin film stacks for modeling multilayer optical coatings, including anti-reflection coatings, bandpass filters, and cutoff filters Surfaces with random or periodic arrays of repeated structures can be created using TracePro’s RepTile™ feature.

Performance and Accuracy
TracePro’s ray tracing engine is fast and accurate, providing complete control of threshold parameters to achieve simulation results quickly with no compromise in accuracy. Analysis Mode ray tracing, unique to TracePro, is a very powerful capability that creates an interactive environment to analyze every surface and object both visually and quantitatively to gauge the feasibility of a design.

Light Sources
TracePro simulates the distribution of luminous intensity, irradiance/illuminance, and flux throughout a model or at selected surfaces by tracing rays using the Monte Carlo method. Light sources are modeled by emitting rays. Additionally, TracePro’s Surface Source Property Utility enables graphed surface source properties to be imported directly from a manufacturer’s datasheet. Ray sets are defined using any combination of three methods:

• Grid – specify spatial and angular beam profile, wavelengths, and dimensions along with beam orientation, polarization state, and degree of polarization.
• Surface – specify angular distribution and emission spectrum from one or more surfaces of any solid object using luminous flux or irradiance/illuminance. Surfaces can also be defined as blackbody or graybody radiators. Any combination of surfaces can be defined as sources.
• Ray File – predefined ray tables consisting of XYZ starting points and direction vectors, polarization states, wavelength data, and the initial flux value or Stokes vector for each ray. Ray files are typically created from source measurements or theoretical calculation.

Analysis and 2D - 3D Optimization
TracePro provides a comprehensive set of tools to view and analyze results of the ray trace, including:
• Irradiance/Illuminance Maps show irradiance or illuminance, CIE, and true color maps of light incident on, absorbed by, or exiting a selected surface.
• Luminance/Radiance Maps can be displayed as true color based on the wavelengths traced.
• 3D Irradiance Plots map irradiance, CIE, and true color plots of the incident, absorbed, or exiting flux onto the selected surfaces or objects in the system view.
• Candela Plots show luminous or radiant intensity in candela or watts/steradian.
• Polarization Maps chart the polarization ellipse for the incident flux onto the selected surface.
• Incident Ray Tables provide tabular output of rays incident on a selected surface.
• Ray History Tables give a complete history of every ray incident on a selected surface.

TracePro offers 2D symmetric and 3D non-symmetric optimizers that enable quick specification of a starting design and interactive control- and segment-point specification. The optimizers have built-in interactive ray tracing tools to quickly diagnose the feasibility of a design, pulling on a control- or segment-point automatically updates any ray trace. TracePro’s optimization process rapidly determines the feasibility of the design, while also allowing results to be continuously monitored and used for subsequent refinement of the model. Complex non-symmetric designs are supported with the 3D optimizer, which is perfect for designing unusually shaped complex lightpipes and LED lenses.

Texture Optimization
TracePro offers the Texture Optimizer, which allows you to optimize the distribution of scattering dots on a backlight. First define a target irradiance distribution, then define a starting point distribution of dots. The optimizer will adjust the density of the dots to achieve your target distributions

Visualization & Rendering
TracePro has several surface and ray display options that help identify problem areas and visualize energy propagation through any optical or illumination system. Large and readable irradiance/illuminance and candela plots with linear or log scales, several color palettes, profiles, and 3D viewing options enable understanding of the flux or irradiance on any surface. TracePro’s Photorealistic Rendering feature uses source and optical properties of the model and real ray tracing and photon mapping algorithms to enable you to visualize your design’s lit appearance from any position.

CAD Integration
TracePro offers seamless integration with SolidWorks using the TracePro Bridge™ for SolidWorks, an add-in to SolidWorks that allows optical properties to be added and saved directly to the SolidWorks model, preserving mechanical and optical properties as models are exported from SolidWorks to TracePro. As a result, design productivity is dramatically improved without sacrificing performance or functionality.

TracePro can generate a variety of ray trace and property reports. For example: Flux Reports provide a summary of surface area, number of incident rays, incident and absorbed flux, and lost flux for all defined sources or as a function of the selected source or wavelength. Bulk absorption and incident flux are displayed for each object. Property Data Reports display the model’s optical surface and object property definitions. Ray Trace Reports display physical and virtual memory usage and elapsed ray trace time.
