Luminous flux measurement integrating sphere UMTB-1000-HFT

turnable Integrating sphere for the luminous flux One of the main applications of integrating spheres is luminous flux measurement of lamps and luminaires. The integrating sphere hereby acts as an integrating element for all light emitted by the lamp. Integration within a closed hollow sphere takes place through multiple reflections on its diffusely reflective surface. Baffles are used to prevent the test lamp from directly illuminating the light meter. Vertical, horizontal and hanging operating position It is always recommended that the test lamps be measured in the same position as that of their intended later use. This makes it possible to also take into account eventual thermal effects. 180° rotation of the UMTB-1000-HFT sphere and the sample holder is hereby possible enabling the test lamp to be operated in a vertical, horizontal or hanging position. Height-adjustable sample holder with a connector for four-pole measurement sockets The sample holder of the UMTB-1000-HFT is designed to be adjustable for the proper alignment of different test lamps at the center of the sphere. In addition to the 10mmØ AP connector for calibration lamps and measurement sockets, it also has a universal adapter plate.
