free stats PI 200 Raman Spetrometer

The PI-200 Raman instrument can be used in the laboratory or on-line for process control. The instrument incorporates a frequency-stabilized, narrow-linewidth diode laser; (Pat No. 6,100,975) a temperature-controlled, optically fast ( f/2.0) fiber-coupled spectrograph; (Pat No. 6,028,67) very low noise Andor CCD camera TE-cooled to -60 oC; and PROspect TM data acquisition and analysis software. The PROspect TM software can be combined with GRAMS/32* for real-time chemometrics and process control applications. 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 (6.6 mm) height coverage of the 1024 x 256 pixel EEV30-11 CCD chip and wide fiber array input (60 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 488 to 860 nm. The spectra can be exported in SPC or ascii formats.
