StellarNet Introduces Low-Cost Fluorescence System

StellarNet has announced the CXR-FS, a low-cost system for fluorescence spectroscopy. The components include a miniature fiber optically coupled, thermo electrically cooled (TEC) UV-VIS spectrometer with concave grating, an LED based excitation source, and a dual read cuvette sample holder.

The excitation source allows for interchangeable LED's emitting at a variety of wavelengths from UV thru VIS. For example UV LED's at 295nm & 345nm are used for analysis of aromatic hydrocarbons. This is a low-cost alternative to expensive lasers, band-pass 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 280-900nm detection range. The TEC improves signal to noise by 60% when exposure times >3 seconds.

The optical bench contains no moving parts for shock-proof durability in a truly portable environment for Lab and Field measurements. The SpectraWiz® software suite is included free and works for Fluorescence applications including biomedical (DNA stains and dyes), amino acid analysis (tryptophan/tyrosine), environmental (water contaminants), and general chemistry experiments, to name a few. SpectraWiz includes Windows drivers with customizable programs for LabVIEW, Visual Basic Automation for Excel, Visual C++, and Delphi Pascal.
