Wavelength (nm)Material QC and Process Control
SPECTRAL EVOLUTION Spectrometers are ideal for onetouch full-range spectroscopic analysis of samples. Transreflectance of three different plastic films were measured using theSPECTRAL EVOLUTION SM-3500 with its included 4° lensforeoptic. Each scan takes less than 1 second. Scans can either
be processed immediately using a computer or handheld PDA(optional accessories) or stored in memory for later processing.

SM-3500 with included foreoptic , optional integrating
sphere and fiber optic & right angle diffuser
