Features
Houses standards in light tight enclosure with easy access to position devices under test
Colour shifted (2856K quartz tungsten halogen (QTH) standards (CIE illuminant A)
Output level of the illuminance calibrator is varied via four neutral density filters, providing five calibration levels
Lab jack and height gauge, featuring a laser alignment aid, allow accurate positioning of device under test
Output level of the luminance calibrator is varied via three neutral density filters, providing four calibration levels
Includes high performance 610 programmable constant current power supply
Calibration traceable to Physicalish Technische Bundesanstalt (PTB, Germany).
