StellarNet Laser Measurement Systems reliably evaluate and keep track of laser frequency and centroid wavelength with approximately 0.05nm spectral resolution BLUE-Wave-NIR2b product spectrometer (785-1200nm).The software package measures the “centroid” of laser to present center wavelength precisely. The centroid calculates the area beneath the laser spectrum then divides the region in https://julianw741gjl2.illawiki.com/user
