Red Tide for the Chemistry Lab

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

  • Fully integrated, preconfigured system covers the 350 to 1000 nm range at 2.0 nm optical resolution (FWHM)

  • See changes as small as 0.1 Absorbance Units

  • Small-footprint system ideal for the laboratory and the classroom

  • Direct-attach deuterium tungsten/violet LED light source and sample holder

  • USB 2.0 interface for fast, hassle-free spectrometer-to-PC connection

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.

Plug-and-Play Operation

The USB650-VIS-NIR interfaces to a PC, PLC or other embedded controllers via USB 2.0 or RS-232 serial port. When using the serial port, the system requires a single 5-volt power supply (not included). Data unique to each spectrometer is programmed internally; our spectrometer operating software reads these values for easy setup and hot swapping among PCs.
