EEPROM Utilization
Nonvolatile memory in each QE Pro contains wavelength calibration coefficients, linearity coefficients,
and a serial number unique to each individual spectrometer. The OOI software application reads these
values directly from the spectrometer, enabling the ability to “hot-swap” spectrometers between
computers without entering the spectrometer coefficients manually on each computer.
About Ocean Optics Software
OceanView 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.
OceanView is a user-customizable, advanced acquisition and display program that provides a real-time
interface to a variety of signal-processing functions. With OceanView, 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 OceanView manual for hardware requirements when using OceanView (see
Product-Related Documentation).
Sampling System Overview
How Sampling Works
Ocean Optics components function in a sampling system as follows in this example:
1. The user stores reference and dark measurements to correct for instrument response variables.
2. The light 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.
6. The spectrometer passes the sample information to Ocean Optics software.
7. Ocean Optics software compares the sample to the reference measurement and displays processed
spectral information.
Modular Sampling Accessories
Ocean Optics offers a complete line of spectroscopic accessories for use with the QE Pro. Most of our
spectroscopic accessories have SMA connectors for application flexibility. Accordingly, changing the
sampling system components is as easy as unscrewing a connector and replacing an accessory.
Interface Options
The QE Pro has both USB and serial port connectors (with the use of an adapter), enabling you to connect
the spectrometer to a desktop or notebook computer via a USB port or serial port.
