Instrument Systems Releases New Calibration LED for Optical Instruments

Instrument Systems GmbH introduces its new calibration LEDs to its ACS-530 Series. The special feature of the new products is their temperature-stabilized high-power LED, according to the company. The new calibration LEDs enable customers to check their instruments easily and reliably. It also means that the photometric value can be recalibrated by customers in conformity with the CIE International Commission on Illumination. Before testing is carried out, the LEDs are calibrated using strictly traceable standards for luminous flux and luminous intensity in the Instrument Systems test lab.


The calibration LEDs have a reproducible and stable optical output power that is essential for reliable measurements. They also feature a particularly high photometric stability of 0.1%. The high-power LED is housed in a casing with exceptionally low thermal conductivity together with a TEC element and a temperature sensor in order to achieve this high stability. The high-power LED is also cooled with the assistance of the TEC element. This eliminates sensitivity to external temperature fluctuations and demonstrates significantly reduced degradation behavior by comparison with heated standard LEDs.

The calibration LEDs from Instrument Systems are supplied in the three basic colors red, green, blue, as well as in white. Over and beyond the photometric parameters luminous intensity and luminous flux, they can also be used for checking results for dominant wavelength, color coordinates and color temperature. A temperature control unit and a constant current source are necessary for operation of the calibration LEDs. They are controlled using the LED Control software developed by Instrument Systems. A PID parameter set optimized for each standard guarantees fast stabilzation and means that the entire measuring system can be deployed immediately.
