USB650-UV-VIS Spectrophotometer for Education

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 200-850 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).

Features

Direct-attach Light Source

The USB650-UV-VIS features the USB-ISS-UV-VIS combination sample holder and deuterium tungsten light source (200-1100 nm). This sampling system holds standard 1-cm cuvettes for easy-to-perform absorbance measurements. The USB650-UV-VIS allows you to control both the intensity of the tungsten bulb and the shutter via software. The USB650-UV-VIS requires an external power supply (included).

Modular Design

Ocean Optics offers complete line of fiber optic sampling accessories and teaching tools to further enhance your USB650-UV-VIS system. Most accessories have SMA 905 connectors for application flexibility; changing the sampling system is as easy as unscrewing a connector and adding new components or accessories.

For even more flexibility, consider the CHEM4-UV-FIBER. An optical fiber based system, the CHEM4-UV-FIBER lets you quickly and easily couple fiber optic accessories, such as reflection probes or transmission dip probes, to the system's light source.

Plug-and-Play Operation

The USB650-UV-VIS interfaces to a PC, PLC or other embedded controllers via a USB 2.0 port. Data unique to each spectrometer is programmed into a memory chip on the USB650-UV-VIS; our spectrometer operating software reads these values for easy setup and hot swapping among PCs.
