Portable hand-held high-precision brightness meter

High-precision small measuring angle luminance meter Japan Konica Minolta LS-100 brightness meter LS-110 brightness meter brightness meter

The LS-100 and LS-110 are the best in class B in the Class B of DIN quality, and they are among the most high-end handheld meters available in the market. SLR (single-lens reflex) In addition to the measurement field and the measurement environment, the viewfinder displays the measured luminance values ​​in a short distance, ensuring that the viewfinder displays exactly the same area as the area to be measured. Allowing the user to hold the device firmly.We place great emphasis on the maximum suppression of streamer phenomena and provide accurate V (λ) correlation (CIE relative to the visual brightness curve.) With close-up lens, even a small diameter of 0.4mm area can .

Applications Japan Konica Minolta LS-100 brightness meter LS-110 brightness meter brightness meter

All types of light sources can be measured using LS series instruments such as lights, traffic lights, airport lighting, lights, LEDs, picture tubes, etc. For example, now you can guarantee the lowest brightness, early replacement of too dark lights, Light production process to establish quality assurance, or check the film screen and other objects to accept the exposure.

Background knowledge (LS-100) Japan Konica Minolta LS-100 brightness meter LS-110 brightness meter brightness meter

The unit of illuminance L is equal to the candlelight per square meter (cd / m 2), From which the principle of illumination measurement can be drawn, the light intensity is named I, the irradiation area of ​​the unit area is A, the irradiation angle is & epsilon;

L = I / (A cos (epsilon;)) Japan Konica Minolta LS-100 luminance meter LS-110 brightness meter brightness meter

Basically, brightness refers to the brightness of the light-emitting surface and / or light source, which is about 1,000,000,000 cd / m 2, And a fluorescent lamp of about 10,000 cd / m 2(Ftl) is also used as the unit for representing the illuminance, and the LS Series can be displayed as desired. 1 ftl = (1 / π cd / ft 2 = 3,426 cd / m2
The measuring angle of the LS-100 is 1 ° and therefore it can be used as a standard dot luminance meter with a measurement range starting from 0.001 cd / m 2The LS-100 allows you to control the measured object at any time without interrupting the measurement process by applying a wide viewing angle of 9 ° and displaying the measured value on the viewfinder LCD. There is an LCD display, plus a tripod screw jack, the user can not be measured by the viewfinder observation. Built-in neutral density eyepiece filter allows the user to measure a strong light source through the viewfinder.

In addition to measuring absolute brightness, the LS Series can also display the percentage of luminance relative to a defined standard (target), which allows you to quickly determine the brightness distribution on a large surface, such as a display, etc. You can also display the luminance peak , Which is useful for measuring flickering light sources such as fluorescent lamps.

The LS-100 provides user calibration options to further improve the existing small deviations of the CIE relative to the visual brightness curve target for a particular light source.

Background knowledge (LS-110)

The unit of illuminance L is equal to the candela per square meter (cd / m 2), From which the principle of illumination measurements can be drawn, the light intensity named I, the irradiation surface area A, irradiation angle & epsilon ;:

L = I / (A cos (epsilon;)) Japan Konica Minolta LS-100 brightness meter LS-110 brightness meter brightness meter

Basically, brightness refers to the brightness of the light-emitting surface and / or light source, which is about 1,000,000,000 cd / m 2, And a fluorescent lamp of about 10,000 cd / m 2(Ftl) is also used as the unit for representing the illuminance, and the LS Series can be displayed as desired. 1 ftl = (1 / π cd / ft 2 = 3,426 cd / m2
This allows the LS-110 to have a good performance for very small light-emitting surfaces and / or small-sphere measurement applications due to the measurement of the narrow angle of only one-third of the size. With the close-up VA-110, even the diameter is as small as 0.4mm Of the area can also be measured. Large measurement range of 0.01 to 999,900 cd / m 2, Covering almost all types of applications. All other features and technical specifications and the corresponding content of the corresponding LS-100.

Product Overview

  • Relative spectral sensitivity
    For luminance measurements, the relative spectral sensitivity of the instrument should be exactly the same as the daytime visual sensitivity of the human eye, as shown by the CIE spectral luminous efficiency V (λ).

The main purpose of Japan Konica Minolta LS-100 brightness meter LS-110 brightness meter brightness meter

  • Measure the brightness of CRT, LED and EL.
  • Measure road and tunnel brightness
  • Measurement of railway system signals
  • Measurement of highway and airport signals
  • Measurement of illuminance and outdoor marking
  • Measurement of lighting equipment and installations
  • Research and measurement testing
  • Measuring device brightness

Key Features Japan Konica Minolta LS-100 luminance meter LS-110 brightness meter brightness meter

  • SLR (single-lens reflex) optical system
    The single-lens reflex design of the LS-100 ensures that there is no discrepancy between the actual measurement area and the area shown in the viewfinder, and by eliminating the influence of contrasts outside the measurement range, this flowless optical system ensures accurate measurement of only the target area .
  • Point measurement for very small target areas
    The LS-100 has a measurement angle of 1 ° and an LS-110 of 1/3 °, which is ideal for measuring the brightness of small sample samples. In addition, by using close-up (sold separately), LS- 100 and LS-110 have a diameter of 1.3 mm and 0.4 mm, respectively.
  • User calibration and color correction function, support large measurement range
    The user calibration function recalibrates any selected brightness as a standard, and the color correction input function can be used to correct the difference in the reading of a particular light source. The above two functions enable the application of multiple brightness meters without error, and thus the implementation of accurate brightness management The
  • Luminance ratio and peak measurement
    Depending on the particular application, the measured value can be set to the luminance instantaneous value, the luminance peak, and the luminance ratio.
  • Two-way RS-232C communication
    Standard RS-232C interface, can be connected with the PC to send measurement data and receive control signals.
  • Light and compact, powered by a 9V battery
    (Power can also be supplied through the DP-10 data printer.)
