The EPP2000-HR High Resolution fiber optic spectrometers are available in several low cost models for UV, VIS, and NIR applications.
The HR 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. Also, optical sensing of temperature, pressure, & position are enabled via Bragg grating technology.
