This Raman instrument design offers very high signal levels while retaining high resolution (~ 4 to 5 cm-1 depending upon excitation wavelength). Patented optical design allows full (3.3 mm) height coverage of the 1024 x 128 pixel CCD chip and wide fiber array input (17 X 100 micron diameter fibers) while retaining a straight fiber array image and good resolution. The system includes a fiber-coupled probe with laser band-pass and elastic light rejection (~10-8) filtering. With the 1200 grooves/mm grating, the spectral coverage is ~ 2100 cm-1 at 785 nm excitation. The grating is adjustable to allow use with excitation from 670 to 860 nm. The spectra can be exported in SPC or ASCII formats.
