The Red Tide Spectrometer is a low-cost, small- footprint lab spectrometer that’s ideal as a general-purpose instrument for your budget-conscious classroom or teaching lab about UV and visible absorbance, reflectance and emission applications.
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).
Our versatile models: USB-650 (wavelength: 350-1000nm), USB-650-UV (200-880nm). Our integrated models: USB-650-UV-VIS (200-880nm) and USB-650-VIS-NIR (350-1000nm).

Spectrometer alone or with sampling system
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.
