QE65000

Description

The Ocean Optics QE65000 Spectrometer includes the linear CCD-array optical bench, plus all the circuits necessary for spectrometer operation. The result is a compact, flexible system, with no moving parts, that's easily integrated as an OEM component

 

 The QE65000 spectrometer is a unique combination of technologies providing users with both an unusually high spectral response and high optical resolution in a small footprint. The electronics have been designed for considerable flexibility in connecting to various modules as well as external interfaces. The QE65000 interfaces to PCs, PLCs and other embedded controllers through USB 2.0 or RS-232 communications. The information included in this data sheet provides detailed instructions on the connection and operation of the QE65000.

The detector used in the QE65000 spectrometer is a scientific-grade, back-thinned, TE Cooled (TEC), 1044x64 element CCD array from Hamamatsu (product number S7031-1006). For complete details on this detector, visit www.Hamamatsu.com.

The QE65000 operates from power provided through the USB (without TEC operation), or from a separate + 5VDC power supply. The QE65000 is a microcontroller-controlled spectrometer, thus all operating parameters are implemented through software interfacing to the unit.
