LS-110 Hand-held and light-weight precision Luminance Meter
Features
Highly-portable, handheld design capable of measurements in a wide range of luminance conditions. Flareless SLR (single-lens-reflex) optical system for high-accuracy measurements. Acceptance angle of 1/3° supports measurement of small target areas.
High precision Luminance-Meter with small angle
The spot luminance meter LS-110, categorized in the upper range of the DIN quality class B, is 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(?) 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, 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.
Applications
Measurement of the luminance of CRTs, LED, and ELs.
Measurement of road and tunnel brightness
Measurement of railway system signals
Measurement of road and airport signals
Measurement of illumination and outdoor signs
Background knowledge (LS-110)
The unit of illumination L equals candelas per square metre (cd/m2), and within this is also the source of this measurement, namely the light strength I emitted per surface area unit A in the angle e :
L= I/(A cos(e))
Basically, luminance specifies the brightness of a luminous surface and/or a light source.The sun has an luminance of about 1 billion cd/m2, fluorescent lamps about 10,000 cd/m2. In some countries the unit foot lambert (ftl) is also used to express illuminance, which the LS can display if required. 1 ftl = (1/p cd/ft2 = 3,426 cd/m2
The narrow angle of measurement of only 1/3° ensures the LS-110 is perfect for very small luminous surfaces and/or measurements in small steradians. With the help of the close-up lens VA-110, areas as small as 0.4 mm diameter can be measured. The measurement range is very large at 0.01 to 999,900 cd/m2 and covers a wide range of uses. All other features and technical specifications correspond to those of the LS-100.
