EPP2000-HR Models
Range 190-1,100nm
The EPP2000-HR High Resolution fiber optic spectrometers are available in several low cost models for UV, VIS, and NIR applications. The cost is a $500 HR upgrade from a standard EPP2000.

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 0.1nm 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.

Optional Configurations
Several units may be daisy chained via a parallel cable or USB-2 hub allowing simple configurations for dual and multi-beam process applications.  

Free SpectraWiz Software
The powerful SpectraWiz® 32 bit spectrometer software is provided free of charge with every spectrometer instrument.  This includes drivers and customizable software for operation on Win95 / Win98 / WinNT / WinME / Win2000 /WinXP.    The SpectraWiz software is considered the "Swiss Army Knife of Spectroscopy and may be used to accurately measure wavelength emissions, reflectance, transmission, absorption, concentrations, and absolute intensities.  In addition to real-time spectroscopy,  SpectraWiz® has built-in applications for SpectroRadiometry, SpectroColorimetry, ChemWiz chemistry lab concentration analyzer, and UV level monitors.

Interface
The system includes a high speed plug & play interface using USB-2 connection.
