Carl Zeiss MicroImaging GmbH is offering its MMS miniature spectrometer modules with 2-D CCD detectors. A single system performs simultaneous high-precision color measurements in up to four wavelengths, from 350 to 950 nm. Applications include monitoring of layer thickness, making color measurements of printed products and LED light sources, and conducting content analyses in the food industry and in agriculture. A four-channel, a two-channel, and two one-channel instruments are available. The modules comprise a glass body and the CCD array, and an array detector enables automatic dark current correction during measurement.
