Luminance Meter LS-150 / LS-160

from Konica-Minolta

The spot luminance meters LS-150 and LS-160, 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 that the viewfinder shows 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 have given special attention to minimize flare and to give precise V(λ) correlation (CIE relative photopic luminosity curve). With the help of a close-up lens, areas as small as 0.4mm diameter can be measured.

Light sources of all types can be measured with the LS, for example signal, traffic lights, airport lighting, lamps, LED's, picture tubes, etc., just about anything that emits light. Now you can, for example, guarantee minimum brightness, exchange lamps that are too dark early enough, build quality assurance into the production of lamps, or check indirectly illuminated objects like movie screens.
Leasing from ca. 70,00 Euro net monthly.

Main features:

  • SLR (single-lens-reflex) optical system
  • Spot measurement for small target areas, with optional lenses down to 0,4 mm
  • Measuring values:  luminance, luminance difference, luminance relationship, hill- and vale measuring
  • Luminance direct readable in view finder and display
  • 1000 data memories
  • USB 2.0 connector for data exchange and power supply
  • User calibration and color-correction functions for wide ranging support
  • Light scatter fuse
  • Measuring and reporting software CS-S20w included
  • Options: 4 Achromatic lenses, mirror reflex finder, long ocular, AC adaptor (see tab "Accessoires")
