User manual KONICA LS-100

[. . . ] In addition, optional close-up lenses can be used to measure areas as small as ø1. 3mm when using LS-100 and ø0. 4mm when using LS-110. 700 750 Wavelength (nm) User calibration and color-correction functions To increase the versatility of the LS-100 and LS-110, both models are equipped with user calibration and color correction functions. The user calibration function allows the meter to be calibrated to a user-selected standard instead of the preset Konica Minolta standard; this function can also be used to standardize the response of several meters. The color correction function allows the response of the meter to be adjusted when measuring colored specimens. Ideally, the relative spectral responsivity of the luminance meter should match V () of the human eye for photopic vision. As shown in the graph above, the relative spectral responsivity of Konica Minolta Luminance Meters LS-100/LS-110 is within 8% (f1') of the CIE spectral luminous efficiency V (). CIE ; Commission Internationale de I«Eclairage f1'(CIE«s symbol) ; The degree to which the relative spectral responsivity matches V () is characterized by means of the error f1'. REDUCTION OF FLARE The degree to which the influence of light from outside the defined measuring area is eliminated is an important factor in the performance of luminance meters. [. . . ] The graph at right shows the 1% effect when a bright point is moved from A inside the 0. 1% measuring area to B just outside the measuring area. 30' 15' 0 15' 30' If the measured value at A is Angle of acceptance ' ' (10 ) (5' ) (5' ) (10 ) in minutes defined at 100%, the measured value at B would be less than A B 0. 1%. Relative sensitivity 1°(1/3°) measuring spot Luminance ratio and peak luminance measurements In addition to measurements of the present luminance, the LS100 and LS-110 can also determine the percent ratio of the measured luminance to a luminance value stored in memory as well as the peak luminance or luminance ratio measured. RS-232C data communication Use of the built-in RS-232C interface allows the meter to be connected to a personal computer.

The concept for the XYZ tristimulus values is based on the premise that all colors are seen as mixtures of these three primary colors. By defining the color matching functions of a Standard Observer, the Commission Internationale de L'Eclairage (CIE), an international organization concerned with light and color, provided the basis for colorimetry in 1931. The tristimulus values y XYZ are useful for specifying a color, but 0. 90 the results are not easily 520 530 visualized. The two-dimensional 0. 80 color (x, y) diagram is 540 510 taken from the Yxy color 550 space, in which Y is the 0. 70 lightness (and is identical 560 to the tristimulus value Y) and x and y are the 0. 60 570 chromaticity coordinates 500 calculated from the 580 0. 50 tristimulus values XYZ. The CIE x, y chromaticity 3000 2500 2000 590 diagram for this color 3500 * 0. 40 4000 A 600 space is shown.

The absolute temperature T (K) of the black body is referred to as the color temperature. The xy chromaticity diagram given on the left shows the relationship between the temperature and color by a locus (black body locus). [. . . ] The xy chromaticity diagram given on the left shows the relationship between the temperature and color by a locus (black body locus). The diagram given below is sometimes used to indicate the color of a light source. Correlated color temperature is used to apply the general idea of color temperature to those colors that are close to, but not exactly on the blackbody locus. For instance, a light source which has a color difference of 0. 01 in the green direction (uv) from a black body which has a color temperature of 7, 000K is indicated as having a correlated color temperature of 7, 000K + 0. 01 (uv unit). 25 00 0. 50 300 0 0. 40 6000 0. 10 0. 00 470 460 450 380~440 0. 20 -0. 0 0uv -0. 0 1uv 480 +0 . 02 uv +0 . 01 uv ±0 0. 25 . 0 20 00 0. 25 2u v 0. 10 0. 20 0. 30 0. 40 0. 50 0. 60 0. 70 1931 x, y chromaticity diagram x 50 30 000 00 0 0 15 0. 30 00 0 00 130 00 100 0 9 00 8000 0. 35 0. 30 7000 0. 35 5000 4500 0. 40 400 0 0. 45 350 0 0. 45 0. 50 0. 55 xy chromaticity chart indicating the black body locus, the isotemperature lines and equal uv lines.
