LED / SSL Measurement
Determination of luminous flux and color with integrating spheres
The SSL / LED test systems from Instrument Systems consist of an integrating sphere of the ISP series and a powerful array spectroradiometer of the established CAS series. This combination delivers the most accurate results with reliable reproducibility.
Our high-quality sphere measuring setups are used for the measurement of individual LEDs and LED modules to large and heavy SSL light sources in accordance with the guidelines of the International Commission on Illumination (CIE). They are frequently used by LED and lamp manufacturers in development and in-process quality control.
Measurement solutions for SSL light sources and LEDs of virtually any size
Precise determination of luminous flux and color
Calibration traceable to PTB
Conformity to CIE 127:2007, CIE S 025 and IES LM-79-08 guidelines
Spectroradiometers of the Instrument Systems CAS 140 or CAS 120 series.
Integrating spheres of the ISP series with internal diameters from 75 mm to 1900 mm and barium sulfate coating for high optical throughput in a broad wavelength range, for measuring single LEDs to large lighting modules. A large number of variants, options and connection options is available to satisfy varying demands in the lab and production.
Auxiliary light source
