TAMPA, Fla., Feb. 23, 2007 -- StellarNet Inc., a maker of miniature fiber optic spectrometers and accessories for spectroscopic and optical measurements, has announced the CXR-FS, a low-cost system for fluorescence spectroscopy. The components include a miniature fiber-optically coupled, thermoelectrically-cooled (TEC) ultraviolet-visible (UV-VIS) light spectrometer with concave grating, an LED-based excitation source and a dual-read cuvette sample holder.
The excitation source allows for interchangeable LEDs emitting at a variety of wavelengths, from UV through VIS. For example, UV LEDs at 295 nm and 345 nm are used for analysis of aromatic hydrocarbons. According to the company, this is a low-cost alternative to expensive lasers, bandpass filters and monochrometers.
Liquid samples are placed the CUV-F cuvette holder which accommodates the SL1-LED excitation source. The spectrometer detects fluorescence via dual-port fiber optic Y-cable that doubles the signal and covers the 280-900 nm detection range. The TEC improves signal to noise by 60 percent when exposure times are longer than 3 seconds.
The optical bench contains no moving parts, providing shock-proof durability in a portable environment for lab and field measurements. The included SpectraWiz software suite works for fluorescence applications such as biomedical (DNA stains and dyes), amino acid analysis (tryptophan/tyrosine), environmental (water contaminants) and general chemistry experiments. SpectraWiz includes Windows drivers with customizable programs for LabVIEW, Visual Basic Automation for Excel, Visual C++ and Delphi Pascal.
