Introduction
Product Overview
The Ocean Optics Maya2000Pro 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.
Ocean Optics Maya2000Pro High-Sensitivity Fiber Optic Spectrometer
The Maya2000Pro 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 Maya2000Pro 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.
TheMaya2000Pro 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.
