High Resolution Spectrometers

The StellarNet EPP2000 Spectrometers are miniature fiber optic instruments for UV, VIS, and NIR measurements in 190-1700nm ranges. Each unit contains a high speed parallel digitizer interface with a 4K word spectral scan memory to provide instantaneous spectral data from the highly sensitive CCD or Photo Diode Array detectors. Various models provide a choice of grating range and slit resolutions. A single strand fiber or probe assembly is input via standard SMA 905 fiber optic connector. The spectrograph's optics is exceptionally robust in a vibration tolerant modular design with no moving parts. The detachable optics assembly and control electronics are protected inside a rugged metal enclosure, suitable for portable, process, and lab applications. Several units may be daisy chained via a parallel cable or USB-2 hub allowing simple configurations for dual and multi-beam process applications. The SpectraWiz software is included to accurately measure wavelength emissions, reflectance, transmission, absorption, concentrations, and absolute intensities. Applications include spectroradiometry (absolute intensity & xy chromaticity), spectrocolorimetry (CIELAB), Optical Emission Spectroscopy, chemical concentration and reaction time-series analysis. EPP2000 interface cards are available for notebook and desktop computer parallel ports (3x faster than USB1) or optional USB2EPP cables that are 40x faster than USB1.
