NEWARK, Del., Dec. 21, 2010 — B&W Tek Inc. has unveiled the Glacier X thermoelectrically cooled miniature fiber-coupled spectrometer for applications that require high performance and portability. It is equipped with a 2048-element linear CCD array, a built-in 16-bit digitizer and a plug-and-play USB 2.0 interface that transfers data at a rate of up to 180 spectra per second. Compared to non-cooled CCD spectrometers, the company says that it offers a higher dynamic range, significantly reduced dark counts and good baseline stability, making it suitable for low-light-level detection and long-term monitoring applications. Wavelength configurations are available from 200 to 1050 nm, with resolutions between 0.6 and 4.0 nm. Flexible custom configurations and application support are also available for OEM customers. Operating temperature is from 15 to 35 °C, readout speed is 500 kHz, and the spectrograph’s f number is 3.2. The combined temperature cooling and regulation, together with the compact form factor make the device attractive to OEM systems integrators. The thermoelectric 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 good signal-to-noise ratio. Applications include UV, visible and near-IR spectroscopy, spectroradiometry and spectrophotometry; wavelength identification; absorbance; reflectance; and OEM optical instrumentation building blocks.
