Instrument Systems Expands Series Of Calibration Standards

 New series ACS-570 for the calibration of luminous flux and intensity of LEDs 

Munich-based manufacturer of light measurement technology Instrument Systems has unveiled a new calibration standard of the ACS- 570 series. Together with the PSU 10 controller, the company says it now offers its own all-in-one solution for the calibration of luminous flux and luminous intensity of measurement systems.

Measurement systems supplied by Instrument Systems can be  checked with the LED calibration standards of the ACS-570 series, and if necessary recalibrated in relation to the absolute photometric value, according to the company.

Luminous flux and averaged LED intensity are calibrated according to the CIE 127:2007 substitution method. The test labs of Instrument Systems, accredited to ISO 17025, guarantee a high degree of precision and direct traceability to the national reference standard of the German National Metrology Institute (PTB).

The ACS-570 series is said to be suitable for diverse laboratory uses and challenging demands in the production environment.

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.
