Introduction
Product Overview
The Ocean Optics USB2000-FLG Spectrometer is a, high-performance, miniature fiber-optic
spectrofluorometer designed from our popular USB2000 model to include an advanced detector and
powerful high-speed electronics. The USB2000-FLG Spectrometer is preconfigured for use with
fluorescence applications from 380-1050 nm. It contains proprietary Silver AgPlus Mirrors, which absorb
ultraviolet light and provide an increase in sensitivity of 10-35% over the standard USB2000 and
USB4000 Spectrometers.
The USB2000-FLG contains custom firmware that allows you to program a variable delay of 5–500
microseconds between a Single Strobe signal and the commencement of an acquisition. You can enable
this Gated mode entirely through software configuration, and you can easily control the Gated mode via
the software interface. The PX-2 Pulsed Xenon Source is the best excitation source to use with the
USB2000-FLG’s gated mode.
Data programmed into a memory chip on each USB2000-FLG 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 USB2000-FLG 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 USB2000-FLG, like all USB devices, can be controlled by our
SpectraSuite software, a completely modular, Java-based spectroscopy software platform that operates on
Windows, Macintosh and Linux operating systems.
