Color meter adapted to deal with LED and OLED lighting

Offering the ability to measure a variety of light sources accurately and with ease, a next-generation chroma meter takes into account greater adoption of LED and OLED lighting. The CL-200A Chroma Meter from Konica Minolta Sensing Americas Inc. (KMSA; Ramsey, NJ) is the successor to the CL-200 Chroma Meter.

Many white LEDs are comprised of a blue LED that's coated with yellow phosphor, so that the resulting white light is actually a mixture of the yellow light emitted by the yellow phosphor coating and the blue light emitted by the blue LED. Since the wavelength distribution of the blue LED emission spectrum differs from LED to LED, the white light generated also varies, making it very important to control not just brightness but also color when white LEDs are measured. KMSA says the CL-200A can obtain all necessary indexes for controlling white LED light in a single operation.

As an additional feature, the CL-200A's receptor head can be removed from the main body and reconnected using the optional remote adapters to allow measurements to be taken with the receptor placed far away or in an isolated darkroom environment. Measurement data can be transmitted from the CL-200A to the included software program, which displays measurements on the chromaticity chart, classifying each measurement by rank. KMSA will begin shipment of the CL-200A by the end of July 2010, with advanced orders already being accepted.
