The Advantages of a Compact, Thermoelectrically-Cooled Fiber Optic Spectrometer for Raman and Fluorescence Spectroscopy

18 Sept 2014

This application note demonstrates the benefits of a TE cooled spectrometer by comparing the technology with a non-cooled device, configured for both fluorescence and Raman spectroscopy.

Glacier X ‒ TE Cooled CCD Spectrometer

B&W Tek, Inc.

The Glacier X is the smallest TE cooled spectrometer on the market, making it the perfect solution for applications that require high performance and portability It is equipped with a 2048 element linear CCD array, built-in 16-bit digitizer, and high-speed USB 2.0 interface.Compared to non-cooled CCD spectrometers, the Glacier X miniature spectrometer offers higher dynamic range, significantly reduced dark counts, and superior baseline stability, making it the ideal spectrometer for low light level detection and long-term monitoring applications. Wavelength configurations are available from as low as 200nm to as high as 1050nm with resolutions between 0.2nm and 4.0nm.Custom spectrometer configurations and advanced application support are available for OEM customers. The combined temperature cooling and regulation, together with its compact form factor makes the Glacier TE Cooled spectrometer a favorite choice of OEM system integrators. The TE cooling makes it possible for weak signals, such as fluorescence and Raman, to be integrated for sufficient time to accumulate measurable signals for detection, resulting in a far superior signal-to-noise ratio.Glacier X ‒ TE Cooled CCD Spectrometer Features: OEM Version Available 500 kHz Readout Speed Plug-and-play USB 2.0 TE Cooled / Regulated UV - NIR Ranges 16-bit Digitizer

Fluorescence SpectroscopyFluorometers and spectrofluorometers (also called fluorescence spectrometers) are used to measure the intensity and wavelength of fluorescent light emitted from a sample after excitation by illumination. Spectrofluorometers utilize monochromators to select the desired wavelengths, whereas filter fluorometers employ a set of filters. Spectrofluorometers for measuring steady-state fluorescence and lifetime fluorescence (or time-resolved fluorescence) are available, as well as fluorescence microscopes and microplate readers.

Fluorescence can be detected and measured for different purposes using microplate readers, fluorescence microscopes, fluorescence scanners, and flow cytometers.SpectrometrySpectrometry is a technique used to measure the mass-to-charge ratio of ions. It provides valuable information about the composition, structure, and molecular weight of compounds. Used across a variety of fields, including chemistry, biology, and environmental science, spectrometry is essential for identifying substances, analyzing mixtures, and developing new products.
