The EPP2000 spectrometers are miniature fiber optic instruments for UV, VIS, and NIR measurements. 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 a standard SMA-905 connector. The spectrograph's optics are 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.
