Ocean Optics HR4000CG-UV-NIR - Manual (Page 10)

1: Introduction
System Requirements
You can use the HR4000’s USB connectivity with any computer that meets the requirements for the
spectrometer operating software being used (Windows 98/Me/2000/XP, Mac OS X and Linux). See
About Ocean Optics Software .
Alternately, the HR4000 has a serial port for connecting to PCs, PLCs, and other devices with a Windows
32-bit operating system that support the RS-232 communication protocol. However, this connection
method requires an external power supply to power the HR4000, the Breakout Box, and a serial cable.
EEPROM Utilization
An EEPROM memory chip in each HR4000 contains wavelength calibration coefficients, linearity
coefficients, and a serial number unique to each individual spectrometer. The OOIBase32 software
application reads these values directly from the spectrometer, enabling the ability to “hot-swap”
spectrometers between PCs without entering the spectrometer coefficients manually on each PC.
About Ocean Optics Software
SpectraSuite is the latest generation of operating software for all Ocean Optics spectrometers. It is a
completely modular, Java-based spectroscopy software platform that operates on Windows, Macintosh
and Linux operating systems. The software can control any Ocean Optics USB spectrometer and device,
as well as any other manufacturer’s USB instrumentation using the appropriate drivers.
SpectraSuite is a user-customizable, advanced acquisition and display program that provides a real-time
interface to a variety of signal-processing functions. With SpectraSuite, you have the ability to perform
spectroscopic measurements (such as absorbance, reflectance, and emission), control all system
parameters, collect and display data in real time, and perform reference monitoring and time acquisition
experiments. Consult the SpectraSuite manual for hardware requirements when using SpectraSuite (see
Product-Related Documentation ).
OOIBase32 software has been discontinued, but still functions with the HR4000 Spectrometer. Consult
the OOIBase32 manual for hardware requirements when using OOIBase32 (see
Product-Related
Documentation ).
Sampling System Overview
How Sampling Works
Ocean Optics components function in a sampling system as follows:
1. The user stores reference and dark measurements to correct for instrument response variables.
2. The light from the light source transmits through an optical fiber to the sample.
3. The light interacts with the sample.
4. Another optical fiber collects and transmits the result of the interaction to the spectrometer.
5. The spectrometer measures the amount of light and transforms the data collected by the
spectrometer into digital information.
