Luminous flux and radiant power of direc tional fiber optic coupled lamps, LEDs and OLEDs can be measured with a compact size integrating sphere based light analyzer.
Integrating spheres with 150 mm (6 inch) diameters have been found to offer the best compromise between light throughput and sphere functionality.
The X4-UMBB150integrating sphere represents a common configuration supplied with Gigahertz-Optik’s X4 light analyzers.
The sphere geometry follows the CIE recommendations for sources with no backward emission such as LEDs and fiber spot lamps. The application port (1) with 50.8 mm (2 inch) diameter offers a heavy load port frame to handle mounting of lamps and LED measurement adapters (2) and their plug-in holder (3) both available as options. The cosine-corrected X4-BTS sensor (4) can be assembled to the sphere using the UMDP-45 detector port adapter (5) which is baffled (6) to the application port. Because of the limited space inside the sphere the auxiliary lamp (7) , recommend by CIE for compensation of the substitution error, is mounted on the outside of the sphere. The 10 W incandescent lamp can be remote controlled by the optional LPS-100 power supply. The auxiliary lamp is baffled (8) to the application port.
Gigahertz-Optik’s calibration laboratory for optical radiation measurement devices offers calibration of the luminous flux and radiant power of the sphere with the X4-BTS integral detector as well as the wavelength dependent sensitivity calibration of the X4-BTS diode array. |
