This instrument is used for luminance measurements of LCD (liquid crystal display), etc. In addition, you can also measure chromaticity and color temperature of various types of light source and lighting fixtures.
Thanks to it calculating function of average, maximum, minimum, and deviation of memorized values, this model is very effective for luminance and color shading inspections of various displays.
Product quality is maintained uniformized from your intial development to manufacture by making use of 3 types of light source compensation coefficients (for standard A light source, 3 wevelength band emitting type fluorescent lamp and CRT) saved in a built-in memory.
Deviation against your target color is displayed in 4 different types of color system.
This model is equipped with the data compensation function that is useful for data synchronization with your company's standard color values and can dissolve your problem due to instrumental error.
Color management software is available in option, which will be very effective for your color data analysis.
