An integrating sphere is a hollow spherical cavity that features a highly reflective white coating. These devices can be used to measure the total luminous flux from lamps or the power of laser light, ...

LEDs measured on the test bench can produce different photometric and color results in actual operation mounted on the PC board. Also, measuring slight color and flux differences between discrete LEDs ...

In order to meet the efficiency requirements of the latest public lighting regulations, researchers from the School of Industrial Engineers of Universidad Politécnica de Madrid (UPM), in collaboration ...

We offer integrating sphere systems for luminous flux measurements, test/calibration and characterization of LED's, lasers, Laser diodes, lamps, and non-directional sources. The integrating sphere ...
