Spectroradiometer
CS-2000
Highly precise spectral radiance/chromaticity measurement possible from 0. 003 cd/m2
Achieving 100, 000 : 1 contrast measurement
World's top level capability to detect extremely low luminance
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/m2 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. [. . . ] (Measuring angle: 1°; Target luminance: 5 cd/m2 or more; 23°C)
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.
Stable measurement even of periodic light sources
1. Internal synchronization measurement Measurement at numerically-input frequency 2. External synchronization measurement
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 closeup lens is attached)
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
Measurements of various objects are possible by selecting the best-suited measuring angle. 1° is suitable for
Typical targets such as middle- and large-size display units
· LCD, PDP, or EL display panels · LCD panels of cellular phones and digital cameras · Radar and other instrument panels used in airplane cockpits · Large outdoor display screens
0. 2° is suitable for
Small light sources such as LEDs
· Car audio systems · Instrument panels for automobiles · Lamps, fluorescent tube backlights, and other light sources
0. 1° is suitable for
Extremely small light sources or distant lights
· PDP or LCD pixels · Cold-cathode tubes · Brake lamps of automobiles · Traffic signals

Close-up lens for measurement of even tinier areas
(Optional accessory)
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.
