Konica Minolta, a global leader in optical technology, manufactures a complete line of light meters and spot meters to measure luminance, illuminance, chromaticity values, color temperature in Kelvin, and UV radiation.
Konica Minolta light meters are hand-held, battery operated, and lightweight. Several measure continuous and flickering light sources; others are capable of non-contact measurement of light sources or reflective surfaces. Konica Minolta's light and spot meters measure in lux and foot-candles, or foot lamberts and CD/m

This low cost light meter resolves down to 0.1 lux, making it appropriate for use in very low light applications.
The handbook gives details of conversion factors for different light wavelengths allowing more accurate measurements.
Peak hold & hold allow a maximum reading to be recorded or one particular result to be kept. Results can be shown in lux or foot candles.
LM90: 20 lux to 20k lux
(preferred for emergency lighting applications LM92: 200 lux to 200k lux
(more sensitive in higher ranges).

The latest generation of Konica Minolta lux meters, the T-10, replaces the globally successful models of the T-1 series. The small, easy-to-use handheld meters are capable of measuring intermittent light sources, can be connected to each other to form multi-point units, and are easily controlled with a PC. They have an extremely large measuring range of 0.01 to 299,000 1x with automatic range switching, and a large, backlight LCD. And all of that with Konica Minolta's renowned high level of precision in a small, compact design.
Areas of application
Konica Minolta lux meters are used whenever brightness and the quantity of ambient light must be measured. Even the measurement of average values and illumination is possible. Examples of their use include the measurement of workplace and street illumination, the production of lamps, as well as architectural, forestry, and agricultural applications. Deployment in hard-to-reach spaces and under water are possible, just as the metering of very large surfaces and projectors (ANSI lumens) by serial connection of several receptor heads. Metered values can also be visualized graphically and even fully automated by using the PC software.

The spot luminance meters LS-100 and LS-110, categorized in the upper range of the DIN quality class B, are among the best hand meters on the market. The SLR (single lens reflex) optical system allows precise targeting and ensures the viewfinder showing the exact area to be measured, even at very short distances. This makes even precise focussing very easy. In addition to the measurement field and the measurement environment, the viewfinder also shows the measured luminance value. The pistol grip makes handling of the unit very secure. We paid special attention to minimize flare and to give precise V(lambda) correlation (CIE relative photopic luminosity curve). With the help of a close-up lens, areas as small as 0.4mm diameter can be measured.
Areas of application
Light sources of all types can be measured with the LS, for example signal, traffic lights, airport lighting, lamps, LEDs, picture tubes, etc., simply anything that emits light. Now you can, for example, guarantee minimum brightness, exchange lamps that are too dark, create quality assurance in the production of lamps, or check indirectly illuminated objects like movie screens.
