We bring quality to light. ISP 1000 Integrating Sphere for measuring radiant power and luminous flux Product highlights Measurement of total radiant power and total luminous flux of high-power LEDs, LED modules, and lamps Robust sample stage for mounting LED modules and SSL products Lamp post for measuring light sources positioned in an upright or suspended configuration 300 mm measurement port for launching light radiation from outside Auxiliary lamp to compensate for self-absorption The ISP 1000 has been designed with a diameter of one meter specifically for taking precise measurements of radiant power and luminous flux of the larger and more powerful light sources used for solid-state lighting applications and for lamps in general. Two geometries are defined according to the type of test specimen and the test data required: In the 4π configuration1, the samples are mounted inside the sphere, while in the 2π configuration2 the light radiation is launched from outside through a port in the side of the sphere wall. The innovative design of the ISP 1000 minimizes interference from baffles and ports and therefore permits more accurate measurements. The interior surface of the sphere is coated with barium sulfate (BaSO4) and has a reflectance of approximately 97%. The light radiation is guided through a detector port and an optical fiber to the spectrometer. All spectrometers supplied by Instrument Systems can be linked to the sphere. The ISP 1000 has a strong aluminum frame fitted with castors and can be opened completely. Light radiation is emitted in all directions Light radiation is only emitted forward (one hemisphere) light measurement

We bring quality to light. Sample stage Sample stage The internal sample stage is ideal for taking precise measurements of large LED modules. The platform of the sample stage measuring 200 x 200 mm is height-adjustable. This allows the test sample to be precisely positioned at the center of the sphere. The M5 threads at 50 mm centers provide secure fixing for the specimen in the desired position. Power supply and data control for the specimen is delivered conveniently through a 16-pole terminal strip.

We bring quality to light. Auxiliary lamp Temperature sensor The internal lamp post with the adapter for halogen lamps is necessary for spectral and absolute calibration of the ISP 1000. Instrument Systems also supplies a 50 W calibration lamp and precision power supply for customers who want to carry out their own recalibrations. This allows on-site calibrations without having to transport the sphere. Interference from baffles and sample holders that could compromise the measurement results were kept to a minimum when the ISP 1000 was designed. However, the influence exerted by the...
