Glacier T: TE Cooled CCD Spectrometer
The Glacier® T series spectrometer available from B&W Tek is a high-resolution, double-pass transmission-based Thermoelectric Cooled (TEC) linear CCD array spectrometer developed exclusively for Raman spectroscopy.
The Glacier T spectrometer is preconfigured for excitation at 532 or 785 nm, with a high-resolution or wide spectral range option.
This TE-cooled spectrometer is installed with a high-speed USB 2.0 interface, 2048 elementsand an integrated 16-bit digitizer, thus continuously delivering improved, high-throughput results.
The combination of a Glacier T spectrometer with its corresponding excitation laser system and Raman Probe offers a module-level Raman system or OEM building block.
For OEM applications, B&W Tek offers system development and application support.
