Optional close-up lens allows measurements of areas as tiny as ø0.1 mm. Not only general display units but also small
targets can be measured.
It is known that the sensitivity of human vision shifts to blue region in dark
environments, but past instruments did not have scotopic measurement
function. CS-2000A achieves sufcient capability to make it possible with
CS-S10w Professional (standard accessory).
Scotopic vision
In the human eye, there are 2 types of photoreceptor cells, which are cone cells and rod
cells. Cone cells are sensitive to color and rod cells are sensitive to only brightness.
As brightness decreases, the activity of rod cells becomes stronger, and the condition
in which only rod cells are working is called scotopic vision. The peak of spectral
luminous efficiency of scotopic vision is shifted toward blue from the green peak of
photopic vision (vision under brighter conditions) and thus blue objects are perceived to
be brighter.
Measurements of various objects are possible by selecting
the best-suited measuring angle.

Thermal analysis diagram
of the sensor block
The o ptica l senso r, whi ch is t he
heart of the CS-2000, was designed
through precise analysis in order to
eliminate the influence of thermal
distortion of its components on the
measurement values.
World's top level capability to detect extremely
low luminance
* As a polychromator type spectroradiometer (As of March 2009)
1,000,000:1 contrast measurement is now possible!
* When the peak luminance is 500 cd/m2
Opening the curtain on a new age in which people can experience theater ambiance with their home televisions.
The Spectroradiometer CS-2000A enables high-accuracy mega-contrast measurements of the extremes from delicate
shadows to glittering wavefronts which are key to image reproduction performance.
This newest addition to the Konica Minolta Sensing lineup will contribute greatly to
research and development as well as quality control of the most advanced FPDs.
0.0005 cd/m2opens new worlds
With an additional decimal place of performance in
measuring low luminosity even compared to our CS-2000,
which was awarded the ADY 2008 grand prize, the CS-
2000A helps open up a new stage of display development by
enabling the measurement of contrast ratios up to 1 million to
1*1 which is being targeted by the latest FPD technology.
*1 Maximum luminance 500 cd/m2
Highly accurate measurement of luminances as
low as 0.003 cd/m2
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/m2.
Low-luminance measurements: From 0.003 cd/m2
Measurement accuracy: ±2% (Luminance)
Quick measurements even at low luminance
Designed to thoroughly eliminate mechanical and
electrical noise factors, the CS-2000 makes quick
measurements with good repeatability possible even at
low luminance levels.
Measurement time for 1 cd/m2:
Approx. 5 sec. (FAST mode)
* Konica Minolta's previous model CS-1000: Approx. 123 sec.
Low polarization error
The polarization error generated when using 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.

Measuring angle selection: 1°, 0.2°, 0.1°
Minimum measuring area: ø0.1 mm (when the optional close-
up lens is attached)
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/m2or more; 23°C)
Stable measurement even of periodic light sources

3. Multi-integration mode measurement
Measurement for reducing variations due to unsynchronized
