The Konica Minolta CA-100 CRT Color Analyzer is an easy-to-use instrument for white-balance adjustment on CRT production lines, with color measurement and analyzer functions plus data-communication capabilities.
The Konica Minolta CRT CA-100 Color Analyzer was designed to upgrade the white-balance process on production lines for color TV sets and computer color monitors in the CRT industry. The multi-function Minolta CA-100 reduces the time required for white balance adjustment and inspection, and provides numerical values for white-balance control. It is even equipped with data-communication capabilities, allowing it to become part of a computerized quality-control system or even a fully automated production line. Continuing advances in consumer televisions, such as higher reliability, higher image quality, larger screens, and more features, plus the increased used of high-fidelity computer color monitors in image-control applications, make the color-reproduction characteristics of CRTs increasingly important.
To ensure accurate color reproduction, white-balance adjustment must be performed utilizing a high-accuracy, high-reliability instrument. With a variety of internal features plus a wide range of optional accessories to provide additional functions, the Konica Minolta CA-100 can be used to speed up white-balance adjustment and inspection of many different kinds of CRTs. In addition, data communication and measurement control can be performed via an RS-232C or GP-I6 system, making it possible to use the Konica Minolta CA-100 on a fully automated production line.
Features
- Wide luminance measurement range of 0.20 to 999cd/m2; (0.06 to 292 fL) allows
measurement of virtually any CRT. Luminance units of cd/m2 or fL can be changed by the user - Different memory channels (11 standard; expandable to 100 with optional card) can be used to
store calibration values or standard colors for different CRT types. Each channel can be labeled
with a 10-character ID name for easy identification - Measurements can be displayed as xyY (colorimetric coordinates, luminance) or T 4uvY
(correlated color temperature, color difference from blackbody locus, luminance) values.
Measured values are displayed both digitally and on LED analog scales - Range of LED analog display scales can be set by the user between 0.1 and 99%
- A standard RS-232C interface is built into the Konica CA-100 for outputting data to a separate computer or controlling the CA-100 from the computer
