Color Control System

LUMINO METER

LCD, PDP, LED, CRT luminance, chromaticity and
color temperature can be measured in a Single Unit!



LUMINO METER, MODEL NL-1

This equipment can measure luminance, chromaticity and color temperature of Liquid Crystal Display (LCD), Plasma Display Panel(PDP),Light Emitting Diode(LED), Cathode Ray Tube(CRT), light fixtures, and all types of light source.


FEATURES
  1. Compact, Lightweight, outstanding mobility
    Compact, lightweight (approx.380g), easy to operate, cordless with battery drive. Suitable for various measurements, including subcontract delivery and inspection. Use of AC power is possible.

  2. Easy to operate, High Accuracy
    The shading-type reduces the influence of the outside light on the optical unit. Capable of measurement by bringing only the optical unite close to the measured object without the need for "contact"/"non-contact". No focus adjustment required, visual check, big-sized tripod and large dark room.

  3. Decreased error associated with measuring range
    This original technique decreases the error associated with the large measurement capacity(0.10~99,990cd/m2)and the small range for coping with not only LCD but also high-luminance display.

  4. Memory of Measurement Values and Computation (Average, Minimum, Maximum, Deflection)
    Capable of storing up to 16 measurement values in the memory. NL-1 is very effective for uneven brightness inspection and uneven color inspection on display, because NL-1 has a memory capacity for measurement values and computation functions.(Average, minimum, maximum, deflection)

  5. Input Function of Coefficient for Light source Correction
    It is possible to measure the accurate chromaticity, because 3 kinds of light-correcting coefficient(Light sources A, fluorescent lamp of R.G.B., CRT) have already been entered. The use of this function is useful to maintain quality at all stages, including the manufacturing line and the development department. The unit difference of plural units is kept at a minimum.

  6. High measurement accuracy
    The use of five sensor leads to improved accuracy. These sensors are used to correct the differences in spectral characteristics and the color deflection so as to improve color matching. The use of these sensor solves the problems of variations between different measuring units, convertibility of measurement data, and reproducibility of results.

  7. Accuracy Assurance for any Color Lighting
    Accuracy is assured as follows;
    Light sources A~+- 0.002
    Light sources A + Color filter ~ +- 0.01
    Fluorescent R.G.B. lamp+ Color filter ~ +- 0.01

    The Chromaticity accuracy is assured not only for light sources A but also for fluorescent light soures for which it is difficult to assure a high accuracy. Also the accuracy of LCD back-light is ensured because of the use of a fluorescent R.G.B. lamp.

  8. Separation of the Optical and Measuring Units
    Optical and measuring units can be separated with the use of an extension cable. Reading of data is not influenced by differences due to the field of view of the LCD. This function is very useful for line-sensor installation.

  9. Input of Standard value and deflection display function
    The deflection to standard color on 4 kinds of color system is displayed. It is possible to measure color differences. Standard colors can input a maximum of 8 data in units by key-input or by using measurement values.

  10. Memory Function for User's calibration Standard values
    The NL-1display value can be corrected by use's standard light sources. Correction coefficients can be entered for up to 8 measurement values or by key input. This function fully solves problems such as differences associated in with the use of various measuring units, the use of new type of unit and the use of several units.

  11. With Recorded-Output and BCD Serial-Output
    It is possible to connect recorder-output to the recorder. It is possible to change BCD serial output to RS-232C. It is possible to transmit the data to a personal computer. This function is very useful for trend control, auto-measuring, the statistics and it is also possible to connect NL-1 in parallel to a maximum of 15 units.

  12. Extensive Color-System Functions

    Built-in 4 functions
    Chromaticity Conditions 1) x, y, L
    2) u', v', L
    Three Stimulation (Tri-Stimulus) Values 3) X, Y, Z
    Correlated Color Temperature 4) TC, duv, L

  13. Cost performance
    Pricing is significantly lower than the past.
