LS-160 Datasheet
The Konica Minolta LS-160 Luminance Meter measures luminance with a 1/3° measuring angle over a range of 0.01 to 9,999,000 cd/m², a spectrum ranging from extremely dim to blinding light. Konica Minolta LS-160 meters capture luminance with a spectral response rivaling the luminous efficiency of a human eye, ensuring measurement results synch with visual evaluation. Lightweight, compact and AA battery-powered, the Konica Minolta LS-160 is a full portable and field-ready device.

A bright viewfinder increases the ease of targeting desired measurement areas, and in automatic mode, the measurement time will be automatically set in response to the target's brightness. Choose from a lineup of four lenses which enable the measurement of microscopic target areas. Once the Konica Minolta LS-160 collects your data, the included utility software allows you to control the meter from a PC and conduct user-specified measurements or assemble data into graphs and list for use in spreadsheets.
