StellarNet Inc. - EPP2000 High Resolution Spectrometers

The EPP2000-HR High Resolution fiber optic spectrometers have double the resolution over standard models with the same grating.  The wavelength range is reduced by the same factor.  Resolutions better than 0.1 nm can be achieved depending on selected model range, detector, and slit size.  Applications include wavelength monitoring and characterization for tunable lasers / LEDs and other sources such as elemental emissions from plasma & Laser Induced Breakdown Spectroscopy.
