Thanks to its user-friendly graphical interface and its numerous modules and libraries, SPEOS’ work is intuitive and transparent.

It is a natural extension to mechanical CAD software for total virtual prototyping. SPEOS imports and exports your mechanical CAD files (IGES, STEP, SAT, DXF formats and native Catia, SolidWorks formats). The integrated modeller includes all the advanced modelisation functions (primitive, extrusion, Boolean functions…).

To simulate the path of light rays, you apply surface and material properties to your objects. Incorporated within SPEOS are the most complete surface state and material models on the market (BRDF, coatings, spectral absorption, volume diffusion). Our libraries, constantly being enlarged, make it easier for you to design and enable you to accurately characterise the model in your project. Our engineering department can also carry out all the measures necessary to characterise a specific material.

From our catalogue you can choose the (already modelled) lamps which you use most often (incandescent, LED, arc lamps, laser diodes…). What’s more, with the spectrum editor, modify the spectral characteristics of your source.

Before calculating, the interactive ray tracer allows you to judge the efficiency of your system. Representation in 3D affords you an overall and immediate understanding of the system and its faults.

The total 3D approach validates your system before carrying out the simulation. Simulations and calculations provide you with the data needed to check the quality of the system (illuminance, intensity, luminance, point luminance, colorimetry). These results are easily exploited in SPEOS’ virtual photometric laboratory (VP lab). Our physical modelling of light propagation and our calculation algorithms mean an accuracy to the order of +/- 5%.

Over fifteen years of experience in the domain of optics and information technology have enabled us to establish SPEOS as the essential tool for the virtual prototyping of lighting systems.
