Illumination Simulation Raytracing

GENERAL DESCRIPTION

The illumination or irradiance of test items (optical, infrared, heaters), as is regularly performed in the thermal facilities of the Test Centre, are accurately modelled using a raytracing software called LightTools.

The source radiance and performance can be accurately simulated, and the applicability can be verified for the customer using the test item’s 3D CAD model, e.g. impingement on volumetric features, spill over and stray light phenomena. Validated simulation models exist for the Large Space Simulator and the VTC-1.5 thermal vacuum facilities.

LIGHTTOOLS KEY FEATURES

  • Wide array of powerful analysis features
  • CAD based interface for visual representation
  • The homogeneity and collimation angle modelled for any specific set of customer requirements
  • Radiometric surface energy mapping
  • Accepts most CAD model formats (STEP etc)
  • Infrared lamp simulation
  • Illumination optimization capabilities
