McPherson is a manufacturer of scientific instruments, with over 60 years’ of experience. We specialize in high performance spectrometers and purpose built spectroscopy systems. We also know the soft x-ray and vacuum ultraviolet region and provide related state of the art components and services. Our optimized spectrometers are for wavelengths from 1 nanometer to 20 microns and energies from 0.05 eV up to 2 keV.
Triple monochromator for Raman spectroscopy
The McPherson triple monochromator uses exclusively reflective optics and is capable of working deep into the ultraviolet, below 190 nanometers if necessary. It is efficient. The triple can be equipped with many different diffraction gratings and works fast as f/5. That is more light gathering power than many single spectrometers! For Raman applications the rejection edge can be set close as 4cm-1 from Rayleigh scatter. "We got some pretty amazing data…" remarks Prof. D. Reznik of the Time resolved Raman Spectroscopy and Neutron Scattering Lab, University of Colorado.
