LS-150 Luminance Meter
The LS-150 Luminance Meter (successor to the LS-100), with compact and ergonomic design, is a highly accurate luminance meter with a spectral response that closely matches the V(λ) spectral luminous efficiency function of the human eye, providing measurement results that correlate with visual evaluation.
The LS-150 uses a single lens reflex (SLR) optics system which provide precise control over targeting and ensures that the viewfinder shows the exact area to be measured, even at very short distances. Areas as small as 1.3mm in diameter (when using optional close-up lenses) can be also be measured accurately. The value of the measured luminance is displayed both inside the viewfinder and the external monochrome display.
The LS-150 conform to DIN 5032-7 Class B ans is capable of measuring luminance as low as 0.001 cd/m² and as high as 999,900 cd/m². LS-150 also comes with color-correction and calibration functions bthat allow users to choose a standard luminance and have differences corrected according to any light sources specified.
