Now integrating spheres (ISs), including ones that uses light emitted diodes (LEDs) as primary light sources, have become essential components of modern photometric and calibration systems for optical sensors, digital cameras, photodiodes, and machine vision systems. This work aims to compare the illuminance–current characteristics of several high-power LEDs and to identify suitable sources for a digitally controlled integrating sphere.
