HR2000 Introduction

HR2000 High-Resolution Fiber Optic Spectrometer

EEPROM Utilization

An EEPROM memory chip in each HR2000 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 OOIBase32

OOIBase32 is the latest generation of operating software for all Ocean Optics spectrometers and is available free
to all customers. OOIBase32 is a user-customizable, advanced acquisition and display program that provides a
real-time interface to a variety of signal-processing functions. With OOIBase32, 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.

Note: When using a handheld PC, you will use the OOIPS2000 software instead of OOIBase32. The

functionality of OOIPS2000 is similar to OOIBase32, but it is specifically for the handheld PC.

Sampling System Overview

Ocean Optics fiber optic spectrometer systems consist of low-cost, modular data acquisition components. A
typical HR2000-based sampling system contains four core elements:

• HR2000

Spectrometer

• OOIBase32 operating software
• Light

source

• Sampling optics (varying, depending on application requirements)

How Sampling Works

The following list explains the function of Ocean Optics sampling components in the sampling process:

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 OOIBase32.

7. OOIBase32 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 HR2000. 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.
