Konica Minolta CM-508c Spectrophotometers

CM-503c has a 3mm measuring area for measuring small specimen areas such as printed materials or medicine tablets; CM-508c has a larger 8mm measuring area for general-purpose measurements of glossy specimens such as plastics, silk, metallic textiles, etc. both models can use an optional memory card for data storage and can be connected to a computer, printer, or bar code reader for even greater versatility.

Illumination/viewing system
Spectrophotometers CM-503c and CM-508c utilize 45/0(45° illumination/0° viewing) geometry with circumferential illumination to provide accurate measurements of glossy specimens. Light from the xenon lamp source is directed onto the specimen surface at an angle of 45° by 12 optical fibers arranged evenly around the measurement axis (circumferential illumination). Light reflected normal to the specimen surface is then collected for measurement.
