HR2000+ Data Sheet Description The Ocean Optics HR2000+ 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 HR2000+ 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 HR2000+ 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 HR2000+. The detector used in the HR2000+ spectrometer is a high-sensitivity 2048-element CCD array from Sony, product number ILX511B. (For complete details on this detector, visit Sony’s web site at Ocean Optics applies a coating to all ILX511 detectors, so the optical sensitivity could vary from that specified in the Sony datasheet). The HR2000+ operates from the +5V power, provided through the USB, or from a separate power supply and either a USB or RS-232 interface. The HR2000+ is a microcontroller-controlled spectrometer, thus all operating parameters are implemented through software interfacing to the unit. The HR4000 Breakout Box (HR4-BREAKOUT) is available from Ocean Optics for use with the HR2000+ Spectrometer. The HR4000 Breakout Box is a passive module that separates the signals from their 30-pin port to an array of standard features found on the HR2000+ Spectrometer.

Internal Operation Pixel Definition A series of pixels in the beginning of the scan have been covered with an opaque material to compensate for thermal induced drift of the baseline signal. As the HR2000+ warms up, the baseline signal will shift slowly downward a few counts depending on the external environment. The baseline signal is set between 90 and 140 counts at the time of manufacture. If the baseline signal is manually adjusted, it should be left low enough to allow for system drift. . The following is a description of all of the pixels, both as they exist on the hardware device and...

Timing Signals Strobe Signals Single Strobe The Single Strobe signal is a programmable TTL pulse that occurs at a user-determined time during each integration period. This pulse has a user-defined High Transition Delay and Low Transition Delay. The pulse width of the Single Strobe is the difference between these delays. It is only active if the Lamp Enable command is active. Synchronization of external devices to the spectrometer's integration period is accomplished with this pulse. The Strobe Delay is specified by the Single Strobe High Transition Delay (SSHTD) and the Pulse Width is...
