19 Dec 2008 A complete Raman spectroscopy system can be assembled using BTC661E, Raman spectroscopy laser and fiber optic probe also offered by B&W Tek. Please visit www.bwtek.com The BTC661E is a high resolution and high sensitivity compact spectrometer for Raman spectroscopy. The spectrometer is designed with a unique folded dual pass optical system for high photon throughput and features an extremely low dark noise, back-thinned CCD array that can be thermoelectrically (TE) cooled to -20° C. The narrow pixel width of the array supports high spectral resolution. The BTC661E is an ideal building block for OEM manufacturers and benchtop end-users alike. Four different models are offered for use with excitation lasers of 532 nm or 785 nm and in either wide range or high resolution configurations. BWSpec™ software with drivers for Thermo GRAMS/AI® and LabView® included. www.bwtek.com |
