This Item Has A Current Calibration!   Konica Minolta LS-100 Hand-held SLR Precision Luminance Meter   Light sources of all types can be measured with the LS-100, for example signal, traffic lights, airport lighting, lamps, LED's, picture tubes, etc., just about anything that emits light.   Includes Hard Carrying Case & Accessories As Listed Above!     Working Condition: Excellent Condition: Refurbished Calibrated: Yes Warranty: 90 Day Exchange     LS-100 Hand-held and light-weight precision Luminance Meter Main Features SLR (single-lens-reflex) optical system The LS-100's single-lens-reflex design ensures that there will be no deviation between the actual measurement area and the area indicated in the viewfinder. Eliminating the effect of illumination outside the measurement range, this flareless optical system ensures accurate measurement of only the target area. Spot measurement for small target areas With acceptance angles of 1° and 1/3° respectively, the LS-100 is ideal for measuring the luminance of small specimens. Furthermore, a close-up lens (sold separately) can be used to achieve a 1.3-mm measurement diameter for the LS-100. User calibration and color-correction functions for wide ranging support With a user calibration function allowing recalibration to any standard luminance that you select and a color-correction input function for correction of indication differences for specific light sources, multiple luminance meters can be used without error for extremely detailed luminance control. Luminance ratio and peak value measurement Based on the particular application, measurement values can be set to instantaneous luminance, peak luminance, and luminance ratio. The spot luminance meter LS-100, 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.   Applications Measurement of the luminance of CRTs, LED, and ELs. Measurement of road and tunnel brightness Measurement of rail-system signals Measurement of road and airport signals Measurement of illumination and outdoor signs Measurement of illumination equipment and devices Research and measurement testing Measurement of device brightness   LS-100 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 ? : L= I/(A cos(?)) 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/? cd/ft2 = 3,426 cd/m2 With its 1° angle of measurement, the LS-100 represents the standard spot luminance meter. Its measurement range starts at 0.001 cd/m2 and is therefore able to meter extremely dark surfaces. With the large 9° field of view and the measured value displayed on an LCD in the viewfinder, the object of measurement can be controlled at all times without taking the LS-100 from your eye. A second LCD display on the exterior of the meter, plus a tripod screw port, allows the user to take measurements without looking through the viewfinder. A neutral density eyepiece filter is included to allow the user to measure strong light sources using the viewfinder. Besides the measurement of absolute luminance, the LS can also display relative luminance as a percentage of a defined standard (target). With this function, the brightness distribution on large surfaces such as monitors can be rapidly ascertained. The peak luminance value can also be displayed on command, useful when measuring flickering light sources such as fluorescents. In order to further improve the already negligible deviation from the targets of the CIE relative photopic luminosity curve for certain light sources, the LS-100 offers the option of user-calibration. 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.
