What is ASET?

Wednesday, August 31, 2011

Angular Spectrum Evaluation Tool (ASET) is central to the AGS Light Performance diamond grading system.  The ASET device is a viewer that produces a color coded view depicting how a diamond is handling light.  Red and green both represent light that is being returned to the eye.  Red represents the most intense light entering the diamond from the highest angles directly from the overhead light source.


ASET theory is at the foundation of the AGS system and is embedded in the sophisticated ray tracing software that is used to calculate light performance.  For more information see our page on the ASET framework and tools.


To see an interesting case study highlighting the practical value of this ingenious tool please see this article on ASET.


Whiteflash provides a variety of valuable diagnostic light performance images on every certified diamond we sell.  For more information on the value of each and how to put  all the imaging information together for a complete understanding of the light handling properties of the diamond, please see our Diamond Imaging page.
