World's top level capability to detect extremely
low luminance
* As a polychromator type spectroradiometer (As of November 2007)
100,000:1 contrast measurement is now possible!
* When the peak luminance is 300 cd/m
Since the commencement of high-definition TV broadcasting, there is an accelerating proliferation of high-quality
display devices which support full HD for reproduction of sharp, high-resolution images. State-of-the-art technology is
now achieving tone reproduction with contrasts of 100,000 : 1, offering an almost-real feeling. This has spurred technical
competition for reproduction of "blacker blacks" in particular, resulting in the need for an instrument that can measure
extremely low luminance.
In addition, the development of various light-emitting devices, including organic electroluminescent (EL) displays as well
as conventional LCD and plasma displays, requires more accurate spectrum analysis. The CS-2000 is a polychromator-
type spectroradiometer which achieves 100,000 : 1 contrast measurement with the world's top level capability to detect
extremely low luminance levels of 0.003 cd/m
Highly accurate measurement of luminances as
low as 0.003 cd/m

Konica Minolta's original optical design and signal-
processing technologies provide accurate measurement of
luminance/chromaticity down to extremely low luminances of

0.003 cd/m
.
Low-luminance measurements: From 0.003 cd/m
Measurement accuracy: ±2% (Luminance)
Quick measurements even at low luminance
Designed to thoroughly eliminate mechanical and
electr ical noise factors, the CS-2000 makes quick
measurements with good repeatability possible even at
low luminance levels.
Measurement time for 1 cd/m
Approx. 5 sec. (FAST mode)
* Konica Minolta's previous model CS-1000: Approx. 123 sec.
Low polarization error
T h e p o l a r i z a t i o n e r r o r g e n e r a t e d w h e n u s i n g a
reflection-type diffraction grating has been minimized
to 2% (measuring angle: 1°). This ensures more stable
measurements of display devices that use polarization,
such as LCDs.
Half bandwidth of 5 nm
A half bandwidth of 5 nm, which is required for colorimetry
(JIS Z 8724-1997, CIE122-1996), is ensured for the
entire wavelength range, allowing accurate chromaticity
measurements.
Selectable measuring angle for measurement of
tiny areas
The CS-2000 enables you to select the optimum measuring
angle according to the application.
Measuring angle selection: 1°, 0.2°, 0.1°
Minimum measuring area: ø0.1 mm ( when the optional close-

Measurement of an organic EL illumination panel during development
Practical design
• The operating temperature range of 5 to 35°C ensures
reliable operation at temperatures in actual work
environments.
• Measurement can be started after a warm-up time of only
30 seconds. (Measuring angle: 1°; Target luminance:
5 cd/m

or more; 23°C)
Stable measurement even of periodic light sources
1. Internal synchronization measurement
Measurement at numerically-input frequency
2. External synchronization measurement
Measurement with line input of vertical synchronization
signal to instrument
3. Multi-integration mode measurement
Measurement for reducing variations due to unsynchronized
measurements or synchronized measurements of sources
having irregular light-emission cycles
