Konika Minolta Releases Successor of Established Hand-held Chroma Meter: The CL-200A

Konica Minolta Sensing, Inc. announces the introduction of the new lightweight portable Chroma Meter CL-200A suitable for measuring the colour temperature of white LEDs and other Light sources. The CL-200A is the successor to the current CL-200 Chroma Meter.

LEDs are known as next-generation lighting because their low energy consumption and efficiency is far better than that of traditional light bulbs. Furthermore, LEDs are environmentally friendly because unlike fluorescent lamps, they use no mercury. After the introduction of high-luminance white LEDs, this technology has become even more practical and popular for general-purpose lighting and as backlights for large-sized LCD displays.

Konica Minolta Sensing has been known as a leading manufacturer of high-performance illuminance meters for a quarter of a century. Konica Minolta Chroma Meters measure not only illuminance but also colour temperature and chromaticity at the same time. Because of this they are well accepted and valued by R&D departments and production lines of LED manufacturers. Thus Konica Minolta Sensing, Inc. enjoys a leading market share in the LED lighting field.

The Chroma Meter CL-200A, which succeeds the current CL-200, has improved operability for white LED measurement. In addition to measuring the colour temperature, chromaticity and illuminance of light sources, the CL-200A also shows the dominant wavelength and excitation purity directly in the display. The CL-200A is a perfect tool to control the quality of new lighting devices such as LED modules. And with the standard accessory software which runs on a PC, users of the CA-200A will be able to rank each measured LED.

Special Features:
Increased operability for white LED and OLED measurements:
Many white LEDs are comprised of a blue LED, which is coated with yellow phosphor. The resulting white light in this case is actually a mixture of the yellow light emitted by the yellow phosphor coating and the blue light emitted by the blue LED. As the wavelength distribution of the blue LED emission spectrum differs from LED to LED, the white light generated also varies. Because of this, it is very important to control not just brightness but also color when white LEDs are measured. The CL-200A is a revolutionary tool to obtain all necessary indexes for controlling white LED light in a single operation.

Remote measurement functionality:
Removal of the receptor head from the CL-200A main body and reconnecting using optional remote adapters allows for measurements to be taken with the receptor placed far away or in an isolated darkroom environment.

LED ranking function:
Measurement data can be transmitted from the CL-200A to the included software program. Using this software it is possible to display measurements on the chromaticity chart and classify each measurement easily by rank automatically and numerically by plotting the data on the chromaticity chart.

The new CL-200A is useful not only for LED manufacturers but also for lighting designers, architects and engineers in the field. When producing illumination for a stage or space, colour temperature, chromaticity and illuminance which are suitable for the space need to be specified and correctly communicated with the workers setting up the event, especially when amenity, safety and efficiency are important to the original designer of the space. The CL-200A is the ideal tool to ensure the stage lighting is exactly as the designer envisaged.

Contributing to the enhancement of the quality and precision indispensable to various industries by providing high-precision measuring instruments.
Derived from our state-of-the-art optical and image processing technologies, Konica Minolta’s measuring instruments help improve quality control and precision in a wide variety of industries. Our display color analyzers for measuring the color and luminance of displays, and spectrophotometers, colorimeters and other color measuring instruments used for essential color management in many manufacturing plants play important roles in supporting various manufacturing industries.
In the growing field of 3D measurement, we have been developing new products for industrial applications with our proprietary technologies, as well as medical and academic applications. In the medical field, our pulse oximeter (for measurement of oxygen saturation) is well regarded.
We are currently integrating development bases and establishing overseas sales companies for reinforcement of business infrastructure. By continuing to provide solutions that respond to changing needs based on our core "technology of light", we will meet the challenges of the new era.
