Red Tide for Physics Studies

The Red Tide USB650 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.


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. Visit Pasco for details.

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

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.
