ACS-530 Series incorporates newly developed LED Calibration Standards to produce a single stabilized high-power LED which is calibrated to luminous flux and luminous intensity or Averaged LED Intensity.
This enables spectroradiometers manufactured by Instrument Systems to be checked easily and the photometric value to be recalibrated as necessary. The LED Calibration Standards allow customers to test their measuring instruments conveniently. They can also be tested independently on site and can be recalibrated in conformity with the substitution method recommended by the CIE International Commission on Illumination - without the inconvenience of having to return the instrument.
Calibration LEDs come in three basic colors: green, red, blue, as well as in white, which covers the entire visible range.
To operate to LED calibration strandards, a temperature control unit and a constant current source are necessary. They can be controlled by using the LED Control software developed by Instrument Systems.
