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).

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.
