      The LMK98-3 Color camera is equipped with a filter wheel adapted to the color matching functions of the 2° CIE standard observer (CIE 1931) for color measurement. Thus, luminances and color coordinates can be measured in a spatially resolved way.The filter wheel has 6 filter positions, with 4 filters being required for color measurement. Furthermore, the measuring system can be equipped with additional filters for the scotopic luminance V'(λ), the circadian principal function C(λ), with an IR filter (measurements in the NIR range λ=780-1000 nm) or a clear glass filter.
Feature
  • Complex evaluation of luminous and illuminated scenes by means of the photograph of an image-resolved luminance distribution
  • Simultaneous recording of a big number of connected measuring data easy data analysis (at a glance)
  • Luminance distributions in measuring images L(x,y)
  • Derived lighting-engineering parameters such as illuminance distribution E(x,y) and luminous intensity distribution I(x,y)
  • Statistical data for being used in calculation programs (z.B. EXCEL®, MatLAB®, LabVIEW®)
Application
  • Night design
  • Measurement of headlamps
  • Measurement of lamps and luminaires
  • Exterior lighting ex:roads and tunnels
  • Interior lighting
  • Display measuring
