Calibration Services
Photometry and Radiometry: Light Meter
Illuminance Meter / Lux Meter
Illuminance is defined as incident luminous flux per unit area, which is equal to lumens per meter-square, or the lux (lx).
SCL can provide calibration services for illuminance measuring equipment (e.g. illuminance meter, lux meter, and light meter) from 1 lx to 3000 lx at correlated color temperature of 2856 K.
The calibration system comprises of a 6 m photometric bench, a reference photometer, a reference colorimeter, standard light sources and a precision distance measuring system.
Illuminance meter under test is calibrated against the laboratory's reference photometer with calibration and measurement capability (CMC) of 1.5%.
Luminance Meter
Luminance is the ratio of the amount of luminous flux per unit solid angle, to the projected area of the source element at a particular direction. The unit of luminance is cd/m2.
SCL can provide calibration services for luminance meter from 10 cd/m2 to 4000 cd/m2 at correlated color temperature of 2856 K.
The calibration system comprises of a 3 m photometric bench, a reference photometer, a reference colorimeter and a 12-inch integrating sphere type uniform luminance source with a precision aperture.
Luminance meter under test is calibrated against the laboratory's reference standards with CMC of 1.5%.
