ACS-530 series calibration LEDs are convenient, reliable tools that let you
check Instrument Systems measuring equipment and, if necessary, calibrate their absolute photometric readings. Instrument Systems calibrates
these LEDs for measuring luminous flux and averaged LED intensity. All
standards used for calibrating purposes are directly traceable to national
labs’ reference standards, enabling calibration using the substitution
method recommended by CIE.
A calibration LED’s radiant power must be reproducible and remain stable,
which requires excellent thermal management. To this end, the LED
and components necessary to stabilize temperature are assembled in
a small housing with very low thermal conductivity. This immunizes the
LED against external temperature fluctuations and achieves excellent
long-term stability and reproducibility, both of which are indispensable to
taking reliable measurements. The LED’s light passes through a diffuser,
producing a Lambertian radiation pattern. The calibration LED may be
used with every Instrument Systems accessory, including the LEDGON
goniophotometer.
