How to Measure Luminance with Light Meters


There seems to be a never-ending list of ways light meters are used in a wide range of industries. These powerful luminance meters give technicians an accurate appraisal of the characteristics of any number of light sources and are used for quality control and other important purposes.

Konica Minolta's LS-100 luminance meter was engineered with many features that make it one of the best light meters available anywhere. It is in the higher range of DIN quality class B and is a light and compact unit that s easy to handle and use. It runs on a 9-volt battery.

This portable meter uses a single lens reflex optical system. With it, users can achieve targeting at an amazingly precise level, with the assurance that, even at short ranges, the exact measuring area will show up clearly in the viewfinder. Users can get accurate light measurement data from small areas measuring just 0.4mm in diameter and, of course, from much larger areas.

The LS-100 light meter's LCD screen displays the value of measured luminance. This value is also shown on the viewfinder. The advantage here is that a technician does not have to move the meter away from his or her face to control the object being measured. When measuring very strong sources of light, safety is ensured through the instrument's neutral density eyepiece filter, which is included. Stability is certain with a uniquely designed pistol grip.

For measuring very dark surfaces, this is the luminance meter of choice with its range starting at 0.001cd/m2. Calibration is made simple with special functions for that purpose as well as for level correction tasks. When correcting luminance levels, users choose a standard luminance, and the unit automatically corrects discrepancies for whatever sources of light users specify.

Other measurement values the LS-100 can read include luminance ratio, peak luminance and instantaneous luminance. Even greater versatility is provided by the fact that the device can be connected to a computer, to which it can relay measurement data results while being provided with control signals.

Konica Minolta is committed to staying on the cutting edge of the technological advancements we build into all our luminance meters. Those who use our instruments in critical measuring applications demand accuracy as well as simple, uncomplicated functions that keep projects moving swiftly. The LS-100 provides technicians, engineers, lab workers and many others with these advantages.

Here is a brief overview of the benefits and features in this portable measuring instrument:

  • A light, battery-powered unit with high dynamic range and accuracy
