Laser wavemeter/spectrometer operating manual

Description	The Laser Wavemeter/Spectrometer is a compact, rugged instrument using a unique combination of an uncoated (Snyder) wedge interferometer and a coated (Fizeau) wedge interferometer to simultaneously measure the wavelength centroid and spectral characteristics of pulsed or CW lasers. Wavelength centroid measurement accuracies are in the range of 1 part in 1,000,000 using the Snyder stage alone. The Fizeau wedge section is capable of resolving spectral details to 0.002/cm and of locating the position of a fringe to 0.0005/cm. Because the Snyder wedge is uncoated, wavelength centroid measurements are possible over the entire detector range of from about 300 nm to greater than 1.0 micron. The coatings of the Fizeau wedge limit spectral analysis to a 200 nm interval in that range. The instrument is currently configured to operate from 600 nm to 800 nm.
