illumia®Pro2 System

Simultaneous thermal, optical, and electrical characterization of LEDs.

Thermal variances at the junction can affect an LED’s performance in terms of color, output, life expectancy, luminous efficacy, and linearity performance. Labsphere’s illumia®Pro2 systems allow users to quickly and accurately test for thermal variances of the device under test.
