USB650-UV-VIS Spectrophotometer for Education

USB650-VIS-NIR Spectrophotometer for Education

The USB650-VIS-NIR packages a high-tech built-in light source, a USB650 Spectrometer, a holder for 1-cm cuvettes, and high-speed electronics into a small-footprint system. The USB650-VIS-NIR provides real-time, PC-based spectroscopy and captures full spectra from 350 to 1000 nm in only 25 milliseconds.

Features

Direct-attach Light Source

The USB650--VIS-NIR uses the USB-ISS-VIS combination sample holder (1-cm cuvette) and violet LED-boosted tungsten light source for measuring relative absorbance. The light source boosts signal in the blue and provides over 45,000 hours of use.

Modular Design

Ocean Optics offers complete line of fiber optic sampling accessories and teaching tools to further enhance your USB650-VIS-NIR 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-VIS-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-VIS-NIR 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 USB4000; our spectrometer operating software reads these values for easy setup and hot swapping among PCs.

Convenient Calibration
