USB650 Red Tide Spectrometer for Education
World’s Most Amazing Low-Cost Spectrometer
The Red Tide Spectrometer is a low-cost, small-
footprint lab spectrometer that's ideal as a general-purpose instrument
for budget-conscious teaching and research labs. The Red Tide has a
wavelength range of 350-1000 nm, and utilizes a detector with 650 active
pixels; that’s 650 data points in one full spectrum, or one data point per
nanometer. Configured with a 25 µm entrance slit, the Red Tide offers ~2.0
nm optical resolution (FWHM).
Flexible Platform, Convenient Interface
The Red Tide is a preconfigured, off-the-shelf
spectrometer where all of the optical bench options, such as grating and
entrance slit size, are already selected. The Red Tide can be used with
various Ocean Optics spectrometer accessories, light sources and sampling
optics, to create application-specific systems for various absorbance,
reflection and emission applications. With its small footprint (89.1 mm x
63.3 mm), convenient USB interface, and integration times as fast as 3
milliseconds, the Red Tide is a great tool for basic lab measurements.
The USB-650 Red Tide comes without a light source or
sample system, allowing you the freedom to choose the accessories that
best fit your application.
The USB-650-VIS-NIR (at right) comes with a
direct-attach light source and sample holder. The light source includes an
LED-boosted tungsten source and a sample holder for 1-cm cuvettes that
connects to the front of the spectrometer. In this configuration, the
system has a wavelength range of 370-980 nm.
The USB-650-UV-VIS includes a deuterium tungsten
halogen light source and a 1-cm cuvette holder. In this configuration,
the system has a wavelength range of 200-850 nm.
Operable with PCs or Dataloggers
The Red Tide interfaces to PCs via its USB port, which
streamlines start-up and supports hot swapping of the spectrometer. What's
more, the Red Tide interfaces to
Pasco's Xplorer GLX (in blue), a unique combination
of datalogger and lab analysis tool that eliminates the need for a PC. The
Xplorer GLX is available from Ocean Optics or Pasco.

The Red Tide also works with Vernier’s Logger Pro
Software. Visit Vernier

Cross-platform Spectrometer Software
Red Tide operates via SpectraSuite Spectroscopy
Operating Software, the first spectroscopy software to run in Macintosh,
Linux and Windows. The Chemistry module for SpectraSuite includes features
specifically designed for educational use, such as a Beer's Law calculator
for absorbance experiments. The Red Tide also works with our educational
distributors' software.
