The newly developed LED Calibration Standards in the ACS-530 Series comprise a single stabilized high-power LED which is calibrated to luminous flux and luminous intensity or Averaged LED Intensity.

This means that the spectroradiometers manufactured by Instrument Systems can be checked easily and the photometric value can be recalibrated as necessary. The LED Calibration Standards allow customers to test their measuring instruments conveniently and independently on site and recalibrate them in conformity with the substitution method recommended by the CIE International Commission on Illumination - without the inconvenience of having to return the instrument.


The calibration LEDs are supplied in the three basic colors green, red, blue, as well as in white, and this covers the entire visible range.

A temperature control unit and a constant current source are necessary for operation of the LED calibration standards. They are controlled using the LED Control software developed by Instrument Systems.


  • Temperature-stabilized, cooled high-power LED in a casing with very low thermal conductivity guarantees exceptionally high photometric stability of 0.1%
  • Applicable for the optical parameters Averaged LED Intensity, luminous flux, color coordinates, dominant wavelength and color temperature
  • Compatible with the full range of accessories supplied by Instrument Systems
  • Calibration is based on national standards
  • Software LED Control with integrated PID control parameters for optimized control of LED, temperature regulation and current source
  • The light exit through a diffuser ensures a Lambertian radiation pattern
  • Light intensity 0.5 - 2 cd or 1 - 3 lm
