Illumination/viewing system
CM-508c
CM-503c
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.
