Orb Optronix released the first electro-thermal-optical characterization system in the world to allow fully automated spectral characterization of light emitting diodes (LEDs). The new ETΦ systems (also known as ETO) from Orb Optronix measure the spectral light output of light emitting diodes while precisely controlling electrical and thermal parameters.

In order to design systems that utilize high power LEDs, the light output characteristics (color and flux) must be known as a function of temperature and electrical input characteristics. ETO makes this fast in easy. Just load a high power LED or LED array, input test parameters ranges, hit start, and in less than an hour, you have all the data necessary to make fundamental design decisions regarding LED selection, thermal management, luminous efficacy, and more.
