Introduction
Product Overview
The Ocean Optics USB4000 Spectrometer is our next generation, high-performance, miniature fiber-optic
spectrometer designed from our popular USB2000 model to include an advanced detector and powerful
high-speed electronics. New features consist of the 3648-element detector with shutter, high-speed
electronics, and interface capabilities to Linux, Macintosh and Windows operating systems. The
USB4000 is responsive from 200-1100 nm, but the specific range and resolution depends on your grating
and entrance slit selections.
The USB4000 is perfect for applications where enhanced electronics, high resolution and fast integration
times are required.
Data programmed into a memory chip on each USB4000 includes wavelength calibration coefficients,
linearity coefficients, and the serial number unique to each spectrometer. Our spectrometer operating
software simply reads these values from the spectrometer —a feature that enables hot swapping of
spectrometers among computers.
The USB4000 Spectrometer connects to a computer via the USB port or serial port. When connected
through a USB 2.0 or 1.1, the spectrometer draws power from the host computer, eliminating the need for
an external power supply. The USB4000, like all our USB devices, can be controlled by our OceanView
software, a Java-based spectroscopy software platform that operates on Windows, Macintosh and Linux
operating systems.

211-00000-000-02-201604 3
EEPROM Utilization
An EEPROM memory chip in each USB4000 contains wavelength calibration coefficients, linearity
coefficients, and a serial number unique to each individual spectrometer. The spectrometer operating
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 OceanView 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:
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.
6. The spectrometer passes the sample information to spectrometer operating software.
7. The software compares the sample to the reference measurement and displays processed spectral
information.
Modular Light Sources and Sampling Accessories
Ocean Optics offers a complete line of spectroscopic accessories for use with the USB4000. 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. Available
accessories include the following:
USB-ISS-UV-VIS Integrated Sampling System for Cuvettes (200–1100 nm)
