*As a color spectroradiometer (established in October 2008)
| A contrast measurement of 100000: 1 has now become possible! *When the measured peak reaches 300 cd/m2 With the comprehensive start of the high-definition television era, in order to better restore sharp, bright, and high-resolution images, the development of some higher quality display devices that support full HD is also accelerating. At present, advanced technology can achieve a brightness level of 100000: 1 contrast, which will give you a more realistic feeling in the picture. Due to the need for instruments to measure lower brightness, there is a technical bottleneck in reproducing some images that are "darker than black". In addition, some other types of light-emitting devices are developing rapidly, such as organic electroluminescence (Organic EL), which, like traditional LCD and PDP displays, requires higher precision spectral radiation curve analysis. CS-2000 is a spectroradiometer with the above measurement functions. Its low brightness measurement has reached a global high level, with a minimum of 0.003 cd/m2 and a maximum measurement contrast of 100000: 1. |
Measurement Example: Measuring an Organic Electroluminescence (EL) Plate During the Development Stage |
Konica Minolta fully combines advanced optical design technology with signal processing technology, providing high precision for chromaticity and brightness measurement at extremely low brightness of 0.003 cd/m2.
Low brightness measurement: starting from 0.003 cd/m2
Measurement accuracy: ± 2% (brightness)
Fast measurement can also be ensured at low brightness levels
The unique design of the instrument fully eliminates mechanical and circuit noise, allowing CS-2000 to perform rapid measurements with good repeatability even at low brightness.
Measurement time at 1 cd/m2:
About 5 seconds (fast mode)
*Previous models of Konica Minolta CS-1000: approximately 123 seconds
Low polarization error
The polarization error caused by the use of reflective diffraction gratings has been reduced to only 2% (measurement angle: 1 °). This ensures the stability of measurement data for display devices such as LCD that use polarizers.
Half wave width of only 5 nm
The instrument has a half wave width of only 5 nm, which meets the requirements for chromaticity measurement (JIS Z 8724-1997, CIE 122-1996), ensuring accurate measurement of chromaticity throughout the entire visible light wavelength range.
Optional measurement angles, capable of measuring very small areas
CS-2000 can choose different optical measurement angles according to your different application objects.
Measurement angle selection: 1 °, 0.2 °, 0.1 °
Minimum measurement area: φ 0.1 mm (when using a close-up lens)
Practical design
The operating temperature range of the instrument is 5 ℃ to 35 ℃, which is similar to the actual working environment, ensuring the reliability of the instrument operation.
The instrument only needs to be preheated for 30 seconds after startup to perform normal measurements. (Measurement angle: 1 °; target brightness: 5 cd/m2 or above; at 23 ℃)
Even light sources with periodic emission characteristics can obtain stable measurement data
1. Internal synchronous measurement
Measurement by inputting synchronous frequency
2. External synchronous measurement
Measurement through external input of vertical synchronization signal
3. Multiple integration mode measurement
Reduce the variation of collected signals during asynchronous measurement or measure light sources with irregular emission characteristics
The concise operation panel and color LCD display make operation more convenient
The color LCD display screen and operation panel are set on the back of the instrument, and the concise button arrangement allows you to more intuitively call the desired functions.
Suitable measurement angles can be selected to meet different measured objects.
