McPherson, the manufacturer of precision optical systems for spectroscopy and science applications, announces a new optical system. It is a triple monochromator designed for making Raman, photoluminescence and Thomson scattering measurements in a variety of ways. The triple configuration allows users to create a bandpass ‘notch’ of select wavelengths and disperse onto sensitive CCD or other array detector. The width and slope of the notched edges can be tailored for the user’s application. For ultimate throughput, McPherson also offers the triple monochromator with astigmatic optics for point to point imaging.
The McPherson triple monochromator uses exclusively reflective optics and is capable of working deep into the ultraviolet, below 190 nanometers if necessary. The triple can be equipped with different diffraction gratings and works fast as f/5.
For Raman applications, the rejection edge can be set close as 4cm-1 from Rayleigh scatter. The triple monochromators tunable wavelength, deep ultraviolet capability and adjustable notch are useful for research and experimental science.
