Luminous flux measurement integrating sphere ISP series

Precise luminous flux measurement of LEDs and luminaires High-quality coating and high measurement accuracy With the ISP series, Instrument Systems has developed a complete family of integrating spheres for individual LEDs as well as lamps and luminaires. As accessories to the CAS series of spectroradiometers they are needed for a wide range of measurement tasks in the lab and production. Thanks to optimized geometry inside the sphere, all integrating spheres from Instrument Systems exhibit high measurement accuracy. The high-quality barium sulfate coating is extremely stable in the long term, and suitable for the spectral range from 240 to 2600 nm. The ISP series of integrating spheres has a lateral measurement port for determining luminous flux in the 2π configuration, in which only the forward-directed radiation is measured. With larger spheres, the sample can additionally be secured in the center of the sphere for measuring the luminous flux in the 4π configuration. Emission in all directions can thus be determined, and total luminous flux can be measured. - Barium sulfate coating with 97% reflection in the visible range - Minimal aging effects and extremely low fluorescence level of coating - Cover the spectral range between 240 and 2600 nm - Ideally tailored to the spectrometer portfolio from Instrument Systems - Spectrometer can be connected by means of a fiber optic cable
