IQCam Luminancephotometer

IQ Cam

The IQCam luminancephotometer is used for luminance measurements and analysis. The photometer consists of a CCD based still frame camera and a computer. Controlled by the computer software, the camera cap­tures images from the measure­ment area with several exposure times and apertures, so that all the luminance values of the area are measured. Simultaneous luminance values of the whole scene are captured in a few seconds. The image consists of 140 000 pixels. The results can be saved as numerical values for later analysis. With the IQCam one can measure and analyse luminance levels and distributions of indoor and outdoor lighting.
