Warranty
Our 3-Year Warranty, currently the best in the industry, covers all Ocean Optics miniature fiber optic
spectrometers – regardless of the application – from manufacturing defects. It ensures you of the highest
level of craftsmanship and reliability for years to come. Our warranty information is located at
The Ocean Optics Maya2000 Series Spectrometers have been engineered specifically for low light-level,
UV-sensitive and other scientific applications such as fluorescence, DNA sequencing and Raman
spectroscopy. These next-generation spectrometers have great quantum efficiency, high dynamic range,
extreme sensitivity and excellent deep-UV (<190 nm) response.
The Maya2000 Series Spectrometers feature the Hamamatsu FFT-CCD back-thinned detector, which
offers excellent performance characteristics. Because of their great native UV-response, FFT-CCD
detectors do not require UV-sensitive coatings, eliminating batch-to-batch variations. Other performance
advantages of this detector include great signal-to-noise characteristics, low dark current and good signal
processing speed.
The Maya2000 Series’ onboard module has 10 user-programmable digital I/O lines for interfacing to
other equipment; and a pulse generator for triggering other devices. You can use the I/Os to flash a lamp,
stop/start a process, and send a message/alarm during the spectrometer’s integration period. The
spectrometer’s operating parameters can be controlled through software. In fact, wavelength calibration
coefficients unique to each spectrometer are programmed into a memory chip right on the spectrometer.

1: Introduction
TheMaya2000 Series’ high-speed electronics have been designed for considerable flexibility in
connecting to various modules and external interfaces, including PCs, PLCs and other embedded
controllers, through USB 2.0 communications. Its USB 2.0 interface enables full spectral scans into
memory every 7 milliseconds.
The Maya2000 Series Spectrometers operate via USB interface. External triggering is not supported by
the Maya2000 Series Spectrometers.
Models
The Maya2000 Series Spectrometers consist of three models, the Maya2000 and the Maya2000 Pro, and
the Maya2000Pro VIS-NIR. The Maya2000 has been discontinued. While these spectrometers have
similar performance for most parameters, the Maya2000 has slightly faster readout time, and the Pro
offers better dynamic range and signal-to-noise. The May2000Pro VIS-NIR offers high sensitivity in the
NIR range while the Maya2000Pro offers high sensitivity in the UV range. See
Maya2000 Series
Spectrometers Specifications for a side-by-side comparison.

System Requirements
You can use the Maya2000 Series’ 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 SpectraSuite Software
EEPROM Utilization
An EEPROM memory chip in each Maya2000 Series 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 SpectraSuite 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
).

1: Introduction
Sampling System Overview
How Sampling Work s
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 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 informatio n to O OI software.
7. OOI software compares the sample to the reference measurement and displays processed spectral
information.
Modular Sampling Accessories
Ocean Optics offers a complete line of spec tro scop ic ac cesso ri es for use with the Maya2000 Series. 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
The Maya2000 Series has a USB connector, enabling you to connect the spectrometer to a desktop or
notebook computer via a USB port. SpectraSuite software is available to operate your spectrometer for an
additional charge.
