The CA-210 from Konica Minolta is a benchtop, tristimulus spot colorimeter that is used principally for the measurement of white balance, white uniformity, luminance, chromaticity, flicker and gamma of various flat panel display devices including LCD.
Viewing Geometry Optimised for LCDs
With an acceptance angle of ±2.5° (for the Large Area Universal Measuring Probes, ±2.5° for the Small Area Universal Probes), display view-angle effects are minimised. At a maximum speed of 20 cycles per second, the CA-210 can measure the brightness and colour of LCDs and a wide range of other display devices. The CA-210 employs tristimulus response XYZ colour sensors that precisely match the CIE observer functions to ensure a chromaticity accuracy of ±0.002 for white and ±0.004 for primary colours. The CA-210 can measure luminance as low as 0.1 cd/m2 which allows for display gamma measurement and correction. The short working distance (30mm) with rubber light hood prevents interference from ambient illumination.
Choice of Measurement Probes
The CA-210 is available with a choice of interchangeable measurement probes and supports connection with up to five probes at a time. If you wish to use the CA-210 with more than one probe at a time, you must purchase a CA-B14 4-Probe Expansion Board as well as the additional probes. A variety of different probes is offered each having different measurement diameters and cord lengths.
The CA-210 Universal Measuring Probes are available with 10 and 27mm measurement areas and cord lengths of 2 and 5m. The universal probes are designed for use in display adjustment, inspection and in the quality control of colour for PDPs, OLEDs, rear projectors, and FEDs. They are also designed for performing adjustment of white balance, contrast and for gamma correction.
The CA-210 LCD Flicker Measuring Probes are also available with 10 and 27mm measurement areas and cord lengths of 2 and 5m. The LCD flicker probes are designed specifically for use in the adjustment, inspection, and quality control of colour for active LCD panels, LCD monitors and LCD TVs. They are also designed for performing adjustment of white balance, contrast and for gamma correction.
O = Recommended
∆ = Measurement possible but with restrictions
X = Measurement not possible
The LCD Flicker and Small LCD Flicker probes are not suitable for measuring CRT displays.
(*1) Measurement of certain display types is not possible with the CA-210. Examples of such display types include:
displays which use PWM for brightness control; displays with backlights which operate intermittently; displays which
write black for each frame.
Gamma Measurement & Correction
The CA-210 can be used to perform measurement and correction of display gamma. A gamma adjustment system will comprise the CA-210, the CA-SDK PC software (standard accessory) and a user-provided pattern generator. The software controls the CA-210 and pattern generator to obtain luminance and chromaticity data for each output level. After calculation of the gamma curve correction factor, software will write the look-up coefficient table to the monitor firmware. White balance adjustment can be performed in a similar manner.
