20120033213 | SPECTROGRAPH HAVING MULTIPLE WAVELENGTH RANGES FOR HIGH RESOLUTION RAMAN SPECTROSCOPY - A spectrograph having multiple excitation wavelength ranges is disclosed. The spectrograph can include a wavelength switching mechanism to switch between different wavelength ranges in accordance with the wavelength of an incoming light signal. The wavelength switching mechanism can include multiple optical assemblies (or elements) corresponding to the different wavelength ranges for processing the incoming light signal. The mechanism can also include a switching component for switching the optical assemblies to align the appropriate assembly with the incoming light signal. Each optical assembly can include one or more transmission gratings to disperse the incoming light signal into multiple wavelengths within a particular wavelength range and a reflecting mirror proximate to the grating(s) to reflect the wavelengths of light back through the grating(s) to photodetectors for measuring to wavelengths to generate a light spectrum. The spectrograph can be used in Raman spectroscopy. | 02-09-2012 |
