CS-200
color brightness meter
The CS-200 colorimeter can measure the brightness and chromaticity of various luminescent products such as large-sized plasma displays, small-sized LCDs and LEDs, outdoor screens, high-voltage lamps, and instrument panels.

The new product launched in the spring of 2006 will be equipped with a new automatic mode that can measure low brightness with high precision.
This newly launched automatic measurement mode can automatically select the measurement speed based on the brightness of the measured object.
This function is particularly suitable for measuring low brightness objects and can effectively avoid the phenomenon of poor measurement accuracy caused by measurement speed.
By using this automatic measurement mode, the measurement speed can be automatically selected to maximize the measurement capabilities of the CS-200 and easily obtain high-precision measurement results.

Product Introduction
Accuracy approximate spectrophotometer for light source incident colorimeter
The CS-200 can achieve high-precision brightness and chromaticity measurements comparable to spectroscope instruments, while retaining the simplicity, ease of use, and affordability of tristimulus instruments.
The CS-200 is equipped with 40 sensors and calculates using a spectral sensitivity characteristic curve (isochromatic function) that matches the sensitivity of the naked eye. Through this developed spectral fitting method, more accurate tristimulus values (XYZ of red, green, and blue) can be obtained than traditional tristimulus colorimeters, achieving higher precision.
It can measure a wide range of brightness levels (from low brightness of 0.01 cd/m2 to high brightness of 20000000 cd/m2, measured at an angle of 0.1 °).
Three measurement angles can be selected: 1 °, 0.2 °, and 0.1 °. The measurement angle can be switched according to the target being measured (from display devices or other objects that require measuring a large area to objects that require measuring a small area such as car audio control panels, car instrument panels, and small LCDs).
Application field

All types of light sources can be measured using CS-200, such as signal lights, traffic lights, airport lighting, lights, etc LED、 Almost all objects that emit light, such as cathode ray tubes, LCDs, PDPs, etc. Due to the development of information technology business, the demand for diversified media in the market is gradually increasing. In addition, with the launch of comprehensive digital broadcasting services, the research and development of various display devices centered on plasma display screens and LCDs has accelerated. The innovation of LED technology has brought significant breakthroughs to the development of LED products, including traffic lights, backlighting for reflective LCDs, and large-sized outdoor display screens.
background knowledge
There are two ways to determine the brightness and chromaticity values of a light source.
The three stimulus type instrument uses three sensors (red, green, blue) to measure the light source, and the sensitivity of these sensors is similar to the sensitivity of the naked eye to light. The filter used to achieve this sensitivity has limited accuracy, so the three stimulus instrument cannot provide accurate readings for all types of light sources. If a certain spectral distribution (similar to the spectral distribution of the light source used for calibrating instruments) is used to measure the light source, accuracy can be achieved.
The CS-200 uses this second method, which measures the spectral emissivity of a light source and calculates it using a spectral sensitivity characteristic curve (isochromatic function) that matches the sensitivity of the naked eye. By using this method, it is possible to avoid filter mismatch and obtain more accurate measurement results.
