Introduction

Konica Minolta Spectroradiometer CS-2000A World’s best for analyzing ultra-low luminance: 1,000,000:1 contrast measurement

The new Spectroradiometer CS-2000A is capable of measuring ultra-low luminance levels of 0.0005 cd/m2 of various light-emitting devices and flat-screen televisions such as LCDs, plasma displays, organic EL displays, LEDs, etc. as well as performing high-accuracy measurements corresponding to scotopic*1 relative luminosity*2.

Product	Spectroradiometer CS-2000A
Start of sales	Planned for Mid November, 2008

In 2007 Konica Minolta introduced the CS-2000, a polychromator-type*3 spectroradiometer capable of measuring ultra-low luminance of 0.003 cd/m2. The CS-2000 has been well received in the FPD (flat panel display) industry and was awarded the 13th Advanced Display of the Year 2008 Grand Prize in the Display Testing Equipment Category.

* cd/m2: candela per square meter. cd (candela) is a unit of luminous intensity for light sources, and is derived from the Latin word for "candle".

The new product, CS-2000A, is a high-end spectroradiometer model attaining an additional decimal place of performance in measuring low luminosity to meet further demands from the market. The CS-2000A, the world’s best ultra-low luminosity analyzer, has the capability to ensure accurate measurements as low as 0.0005 cd/m2 and enables contrast measurements of 1,000,000: 1*4, the contrast achieved by the newest display devices. This new product provides highly accurate measurement results essential for developing and manufacturing LEDs, organic EL displays, and various other light-emitting devices. In addition, the CS-2000A provides results for high-definition displays, responding to the ever-increasing demand for gradation with near-life texture.
In addition, the selectable measuring angle feature allows the user to select the optimal measuring angle according to the application. A close-up lens (optional accessory) enables measurements of even smaller areas.

Furthermore, the CS-2000A provides measurements that correspond to the visual characteristics of a human in low luminosities.

The peak of sensitivity for human vision is known to shift from green to blue in a dark environment; however, conventional measurement instruments are unable to accurately measure these conditions. The new product "Data Management Software CS-S10w Professional", included as a standard accessory, enables highly accurate measurements responding to the scotopic*1 relative luminosity*2, expanding the scope of applications from product development and manufacturing sites to various research fields including environmental science, medical science, and psychology.
