B&W Tek Inc. has unveiled the Glacier X thermoelectrically cooled miniature fiber-coupled spectrometer for applications that require high performance and portability. Equipped with a 2048-element linear CCD array, it has 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. The company says that, compared with noncooled CCD spectrometers, it provides 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 nm. Flexible custom configurations and application support also are available for OEM customers.
