High resolution spectrometer

High resolution spectrometer HR4000

Description

The Ocean Optics HR4000 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 HR4000 spectrometer is a unique combination of technologies providing users with both an unusually high spectral response and high optical resolution in a single package. The electronics have been designed for considerable flexibility in connecting to various modules as well as external interfaces. The HR4000 interfaces to PC’s, PLC’s and other embedded controllers through USB 2.0 or RS-232 communications. The information included in this guide provides detailed instructions on the connection and operation of the HR4000.

The detector used in the HR4000 spectrometer is a high-sensitivity 3648-element CCD array from Toshiba, product number TCD1304AP. Ocean Optics applies a coating to all TCD1304AP detectors, so the optical sensitivity could vary from that specified in the Toshiba datasheet).

The HR4000 operates off of a single +5VDC supply and either a USB or RS-232 interface. The HR4000 is a microcontroller-controlled spectrometer, thus all operating parameters are implemented through software interfacing to the unit.
