OSK21TB101 Contrast tester

Contrast tester
Application
    1. Quality management of high quality ink for RGB color filter of liquid crystal display
    2. Measurement of state of ink particles and dispersion
Features
    1. It can measure the contrast of color filter inks which are used at liquid crystal display
    2. It can measure extinction value of test pieces by measuring the maximal and minimal of transmitted luminance from light source with fixed luminance value
    3. Can easily control and obtain data by original software
    4. The luminance meter and light source are changeable
    5. Automatic calibration
    6. Saving and printout of data
Effect
        Evaluate the quality of ink by simple operation
Specification
        Specifications may be changed according to the environment of the test location
