LMK luminance measuring camera

l = 397

The LMK mobile advanced is a camera based imaging luminance photometer for measurement and analysis in indoor and outdoor lighting. The LMK system is based on Canon EOS 350D digital camera with a CMOS Canon ASP-C sensor. The size of the luminance image is 1728(H) x 1152(V) pixels.

The luminance images are analyzed with LMK LabSoft software. The software is capable to analyze luminance images composed of single images at various integration times to obtain higher dynamic range. The LMK LabSoft software provides calculation methods for glare assessments for indoor lighting (UGR) and outdoor lighting (TI). Together with the LabSoft software and RoadLumimeter, a program developed at the Lighting unit, CIE road lighting parameters can be evaluated.
