Instrument Systems have introduced a new calibration standard in the ACS-570 series. Together with the PSU 10 controller, this offers an all-in-one solution for the calibration of luminous flux and luminous intensity of measurement systems. The measurement systems supplied by Instrument Systems can be simply and reliably checked with the LED calibration standards of the ACS-570 series, and if necessary recalibrated in relation to the absolute photometric value. Luminous flux and averaged LED intensity are calibrated according to the CIE 127:2007 substitution method. Instrument Systems is accredited to ISO 17025, and offers direct traceability to the national reference standard of the German National Metrology Institute (PTB).

Optimised thermal management guarantees reproducibility and a permanently stable optical radiant flux of the LED calibration standard. The LED and temperature control system are housed in a casing with low thermal conductivity and thus insensitive to external temperature fluctuations. Through the combination of the new calibration standard with the PSU 10 power and TEC control unit, Instrument Systems offers an all-in-one solution with fast temperature control and high stability of the operating current. Alternatively, the ACS-570 calibration standard can also be used with power sources and TEC controllers of other manufacturers.
