Introduction
Ocean Optics miniature fiber optic spectrometers and accessories have revolutionized the analytical
instrumentation market by dramatically reducing the size and cost of optical sensing systems. More than
10,000 Ocean Optics spectrometers have been sold worldwide -- striking evidence of the far-reaching
impact of low-cost, miniature components for fiber optic spectroscopy. Diverse fields such as research and
development, industrial process control, medical diagnostics and environmental monitoring have benefited
from access to Ocean Optics technology.
The Modular Approach
A typical Ocean Optics small-footprint system comprises of five basic elements: a Miniature Fiber Optic
Spectrometer, an A/D converter, our operating software, a light or excitation source, and sampling optics.
The light or excitation source supplies light through the illumination or excitation fiber to the sample and
then light interacts with the sample. The light is then collected and transmitted through the read fiber to the
spectrometer. The spectrometer measures the amount of light and the A/D converter transforms the analog
data collected by the spectrometer into digital information that is passed to the software, providing the user
with application-specific information.
This modular approach -- components are easily mixed and matched -- offers remarkable applications
flexibility. Users pick and choose from hundreds of products to create distinctive systems for an almost
endless variety of optical-sensing applications.
S1024DW Miniature Fiber Optic Spectrometer
The S1024DW Deep Well Detector Spectrometer is a 1024-element photodiode array detector for those
applications requiring extremely high signal-to-noise (2000:1) measurements. With the S1024DW, the user
can achieve micro-absorbance unit resolution. In fact, the user can reliably see an absorbance change of less
than 0.00001 absorbance units. Furthermore, the S1024DW can be multiplexed with up to 8 spectrometer
channels and is ideal for high light level applications such as dissolution testing.
The S1024DW accepts light energy transmitted through single-strand optical fiber and disperses it via a
fixed grating across the photodiode array, which is responsive from 200-1100 nm. An SMA 905 connector
allows for easy coupling to an extensive line of fiber optic light sources, probes, chemical sensors, and
other spectrophotometric accessories.
SAD500 Serial Port Interface
The S1024DW interfaces to our SAD500 Serial Port Interface, a 12-bit, 8-channel, microprocessor-controlled
A/D converter with a 500 kHz sampling frequency. The SAD500 can be used to interface to desktop or
portable PCs, as well as to PLCs and other devices that support the RS-232 communication protocol. The
SAD500 A/D converter allows the S1024DW spectrometer to acquire spectra using integration times as rapid
as 31 milliseconds. For increased speed, the SAD500 can be software configured to transmit only a portion of
the spectra or the averages of multiple spectral acquisitions, or a combination of both.
OOIBase32 Spectrometer Operating Software
OOIBase32 Spectrometer Operating Software is our next generation of operating software for all Ocean
Optics spectrometers. OOIBase32 is a 32-bit, user-customizable, advanced acquisition and display program
that provides a real-time interface to a variety of signal-processing functions for Windows 95/98 and
Windows NT users. With OOIBase32, you have the ability to perform spectroscopic measurements such as
absorbance, reflectance and emission; control all system parameters; collect data from up to 8 spectrometer
channels simultaneously and display the results in a single spectral window; and perform reference
monitoring and time acquisition experiments.
