Outline

2D Luminance Colorimeter UA-200A is a latest model of UA series that can measure high accuracy the uniformity of luminance and chromaticity for FPDs, lighting, and interior panels of automobile.

The UA-200A has achieved wide measurement range than one of conventional product. (From 0.0005 cd/m2 to 1,000,000 cd/m2) Also, it has a new function that is layer function and can measure from low luminance to high luminance in a lump by added layer function.

Lens angle Model name
Standard lens UA-200AS
Standard lens with wide attachment lens UA-200AWS
Telescopic lens UA-200AT

Features

  • High chromaticity accuracy : New developed optical filter make it possible to achieve high accuracy of within ±0.008.
    　
  • Measuring time : one sec : Optimized algorithm allows reducing measuring time. *Luminance measuring only.
    　
  • 1.4 mega pixel CCD : 1,376×1024 resolution
    　
  • Expansion of function : Available for high brightness version 10-50,000cd/m2
    　
  • 3 type lens variation : Standard, Wide, Telescopic lens

Applications

  • Evaluation of luminance and chromaticity of LCD, its related materials, and OLED.
  • Evaluation of light distribution of Interior panel in automobile and Car Audio.
  • Evaluation of luminance and color Mura on the LED and OLED illumination.

Standard software

○The standard software can operate an instrument and collect and analyze data.

○Two type software are available for your usage.
    • Standard Edition - Full function are available, including control of UA-200A
    • View Edition       - Viewing and analyzing are available.
                                 Can analyze measured datawithout an instrument.
○New functions

      • Diagonal correction is available for continuous measurement by single recipe

  ⑥Link to LabVIEW
      • Supporting NATIONAL INSTRUMENTS’ development tool LabVIEW

○View mode (Current model)
Pseudo Color View   Contour View   Split Spot
   
The difference in luminance or color on the image is presented by using colored image.
Suited for Mura evaluation		   Indicates the luminance and color difference by using contour line.   Image is dividend with grid pattern and show value of luminance and chromaticity in each gird.

Standard Spot View   Random Spot View   Cross Section View
   
Four type of measurement according to JEITA standard (EIAJ ED-2522/ED-2710). shape and quantity of spots are changeable.   999 points at max can be placed on the image.   Measured data on the cross-section line is shown as graph. The cross-section line can be selected from cross line and diagonal line.

Color diagram View(x,y/u',v') 3D View Histogram View
   
Measured data on each view can be plotted on the color diagram   Measured data show as 3D image.   Statistical graph.
Vertical axis means the frequency, horizontal axis means measured data.

Thumbnail View   Time-series graph view
 
Measured images show as thumbnails.   Variation of measured data with lapse of time shows

Measured data on each view can be saved as csv format.

Image on each View can be saved as BMP/JPG/PNG file.
