Instrument Systems Launches Large Integrating Sphere for Testing SSL Light Sources

1.9 meter integrating sphere for measuring total radiant power and luminous flux

The ISP 2000 from Instrument Systems is the latest pioneering development launched by the leading manufacturer of light measurement systems worldwide. This integrating sphere has been specifically designed with a diameter of 1.9 meters to facilitate precise measurement of total radiant power and luminous flux at lamps, luminaires and large LED modules.

The ISP 2000 is the largest member of the well-established family of premium integrating spheres produced by Instrument Systems. It incorporates all the unique capabilities that brought success to its smaller peers. These characteristics are particularly effective for testing solid-state lighting (SSL) products, conventional lamps and luminaires. The ISP 2000 is equipped with an auxiliary lamp to compensate for self-absorption, a temperature sensor to monitor the thermal conditions of the interior, and a detector port incorporating a fiber adapter to link the sphere with all spectroradiometers from Instrument Systems. The company offers a complete package of calibration accessories for the ISP 2000.

The ISP 2000 can be used to carry out measurements at 4π and 2π geometry. The maximum sample size is 600 mm x 300 mm x 300 mm in the center and the maximum sample diameter is 600 mm at the external measurement port. A lamp holder is available for mounting the test specimen inside the sphere. It accommodates optional adapters for all standard lamp sockets. A sample stage can be used instead of the lamp post for mounting non-standard sample sizes, for example complete luminaires and LED modules. This stage provides a footprint of 200 mm x 150 mm and a 16-pole terminal strip for connecting to a power supply or control circuit. A robust, rail-mounted sliding mechanism delivers light-tight closure for the ISP 2000 and permits the sphere to be opened easily for quick access to the interior.
