Luminance Meter Type 1101
The Luminance Meter is light, portable and
battery powered. It is designed to measure
luminance simply and directly. Its two Mea-
surement-Field Angles, i.e.
1/3°
and 1
o,
give
it a measuring range that spans from
0,01 cd/m
2
to 2000 kcd/m

The measured
values are displayed numerically both in the
viewfinder and externally on the top panel.
The readings are inherently stable due to an
internal automatic calibration of the zero
point. It is spectrally matched to the CIE
standardized curve for human photopic vi-
sion. There are special averaging and peak
detecting circuits which allow it to be used
for flickering light sources such as fluores-
cent lighting, cinema screens, visual display
units etc. There is an output for tape and
level recorders.
