Zemax Development Corporation is using Transmagic, a developer of multi-computer-aided design (CAD) data exchange software, as its 3D mechanical CAD data repair and translation solution.
Optical system design often includes importing 3D mechanical CAD files into Zemax for opto-mechanical stray-light analysis, light-emitting diode (LED) illumination system design and other optical design tasks.
Before importing design files into Zemax, the geometry must form 'watertight' solid models.
Any gaps between surfaces can cause errors in optical analysis.
Transmagic repairs and conditions CAD data from all major CAD applications for translation into Zemax.
Mark Nicholson, vice-president at Zemax Development Corporation, said: 'Our customers struggle with the handover between mechanical and optical engineering - they are optical engineers and not experts in CAD.
'Mechanical CAD packages are three orders of magnitude coarser resolution than what is needed for optical design and errors in mechanical designs may not be apparent in the CAD package,' he added.
Todd Reade, president of Transmagic, said: 'Transmagic is able to simply explain what is wrong with a badly formed CAD file and then easily repair the file with a high resolution before importing into Zemax.
'Transmagic resolves critical geometry issues in design files for the optical industry as well as energy, medical and manufacturing industries,' he added.
Transmagic software is intended to reduce the delays and expenses associated with redrafting models, outsourcing file translations and sharing design data.
