Luminance meters are single element detectors that measure photometric brightness. It is measured in lumens. The Konica Minolta luminance meter measures the amount of light that strikes a surface. These instruments display luminance in either lux or foot-candles and they are lightweight, compact and portable. They can be connected to a PC which can store the measurement data and control the device. The LS-100 series has a single lens reflex optical system to precisely measure very small (0.4mm) diameters at very short distances, making it extremely easy to use.
LS-150 Luminance Meter
A spot meter with a 1° acceptance angle, a minimum measuring area of 14.4mm, and a measuring range from 0.001 to 999,900 cd/m2.
