B&W Tek’s Glacier® T series is a high-resolution, double-pass transmission-based thermoelectrically-cooled (TEC) linear CCD array spectrometer that has been developed especially for Raman spectroscopy. The Glacier T is available preconfigured for excitation at 532 or 785 nm, with a broad spectral range or high-resolution option.
The TE-cooled spectrometer has a 2048-element CCD, high-speed USB 2.0 interface, and built-in 16-bit digitizer and thus constantly provides improved high-throughput results.
Integrating a Glacier T spectrometer with an equivalent excitation laser system and Raman probe offers a module-level Raman system or OEM building block. It comes with system development and application support for OEM applications.
