Spectroradiometer CS-2000
NEW
Highly precise spectral radiance/chromaticity measurement possible from 0.003 cd/m2
Features
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 Φ0.1 mm. Not only general display units but also small targets can be measured.
Measuring distance vs. measuring area
| Measuring distance(Units: mm) | measuring angle | |||
|---|---|---|---|---|
| 1° | 0.2° | 0.1° | ||
| When a close-up lens is attached | 55.0 | φ1.00 | φ0.20 | φ0.10 |
| 70.9 | φ1.39 | φ0.28 | φ0.14 | |
| 350 | φ5.00 | φ1.00 | φ0.50 | |
| 500 | φ7.78 | φ1.56 | φ0.78 | |
| 1,000 | φ16.66 | φ3.33 | φ1.67 | |
| 2,000 | φ34.18 | φ6.84 | φ3.42 | |
- *
- The measuring distance is the distance from the objective lens or the end of the metal frame of the close-up lens.
Comparison of repeatability
- *
- Comparison with Konica Minolta's previous model CS-1000 for target luminance of 0.1 cd/m2
- *
- The y-axis indicates the logarithm when the average of the CS-2000 measured values is assumed to be 1.
Luminance (Lv)
Chromaticity (x)
Chromaticity (y)
High repeatability achieved by an instrument design which thoroughly eliminated mechanical and electrical noise factors.
Measured luminance vs. Measurement times
(Units: sec.)
| Luminance(cd/m2) | NORMAL mode | FAST mode |
|---|---|---|
| 0.003 | 243 | 35 |
| 0.01 | 243 | 35 |
| 0.1 | 155 | 27 |
| 1 | 19 | 5 |
| 10 | 4 | 4 |
| 300 | 3.7 | 3.7 |
Measurement subject: Standard light source A

Thermal analysis diagram
of the sensor block
The optical sensor, which is the 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.
