The Glacier® T series from B&W Tek is a high-resolution, double-pass transmission-based thermoelectric-cooled (TEC) linear CCD array spectrometer particularly designed for Raman spectroscopy.
The Glacier T spectrometer has been preconfigured for 785 nm or 532 nm excitation with a broad spectral range or high-resolution option.
The TE-cooled spectrometer also features a high-speed USB 2.0 interface, a built-in 16-bit digitizer and 2048 elements, thereby constantly delivering improved high-throughput outcomes.
Integrating a Glacier T spectrometer to its equivalent excitation laser system and Raman probe offers an OEM building block or module-level Raman system. In addition, application support and system development are available for OEM applications
