Ocean Optics - CHEM4 Systems for Education

Our CHEM4-series Spectrophotometers for education are small-footprint, PC-based systems designed for chemistry professors, teachers and others who use spectroscopy as a teaching tool. These fully integrated systems -- including spectrometer, light source, cuvette holder -- are available at dramatic discounts. Acquire and display data -- 3648 wavelengths -- in <1 second with our convenient PC-based systems.

Sampling Optics: Direct-attach or Fiber

Each CHEM4 system comes with a fully integrated light source and cuvette holder that attaches to the spectrometer for a remarkably small-footprint system. The cuvette holders for all CHEMUSB4 systems are designed for standard 1-cm square cuvettes.

The CHEMUSB4-UV-VIS has a state-of-the-art, miniature RF-excited deuterium tungsten source. The CHEMUSB4-VIS has a direct-attach combination tungsten and blue LED source. You can separate each spectrometer from its integrated light source to couple the spectrometer to any of our fiber optic accessories and light sources.

The CHEM4-UV-FIBER and CHEM4-VIS-FIBER include a light source and cuvette assembly that attaches to the spectrometer with an optical fiber. The advantage of this design is that the light source can be easily coupled to other fiber optic accessories such as reflection probes or transmission dip probes. The CHEM4-VIS-FIBER comes with a tungsten source and the CHEM4-UV-FIBER uses a deuterium tungsten source.

USB Interface for Easy Startup

All of our CHEM4 systems interface to a PC via USB. All you need is to install the software and connect the included USB cable to your PC to be up and running. Wavelength calibration data are loaded automatically upon startup, and spectrometer power is supplied through the USB.

Software for Linux, Macintosh and Windows

To get the most of your CHEM4 system, you can add our optional student-friendly software, which includes functions for absorbance, transmission, relative irradiance and kinetics measurements.

The systems also work with our SpectraSuite Spectroscopy Software, which works in Linux, Macintosh and Windows operating systems and is available for $199.

Retail price:	$3464

CHEM4-UV-FIBER

The CHEM4-UV-FIBER covers the 200-885 nm range, has optical resolution of 1.0 nm (FWHM) and captures 3648 wavelengths in <1 second. The system is ideal for relative irradiance and emission measurements.

The CHEM4-UV-FIBER combines a USB4000 Spectrometer with modular accessories including an ISS-UV-VIS Integrated Sampling System, a 300 µm solarization-resistant optical fiber and a 1-cm cuvette holder for absorbance measurements.

The advantage of an optical fiber based system is flexibility. Add accessories including reflectance probes and dip probes for even more measurement options.
