As part of the design process, engineers must predict the performance of their LED system and determine if it will meet specifications at real operating temperatures and electrical drive conditions. The ETΦ™ family of LED Characterization Systems (also known as ETO) from Orb Optronix (Kirkland, WA) measures the complete electrical, thermal, and optical characteristics of LEDs.

ETO LED Characterization Systems efficiently measure the quantity and color of light from LEDs over a range of temperatures and electrical input power variables. The systems have both automated data acquisition and mature data analysis features. ETO systems allow users to automatically sequence measurements of light output and spectrum over a wide range of temperatures and currents, and comprehensive data analysis features allow users to quickly and easily view different groupings of data in over 300 graphs.

The ETO system is available with options for integrating sphere sizes from 6 in. to 76 in., a range of source meters and thermal platforms built for the measurement of discreet LED packages or high-power LED arrays and SSL subassemblies.
