McPherson, a manufacturer of precision optical systems for spectroscopy and science applications, has announced a new triple monochromator ideal 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 them onto a sensitive CCD or another array detector. The width and slope of the notches’ edges can be tailored for the user’s application.
The McPherson triple monochromator uses exclusively reflective optics and is capable of working deep into the ultraviolet, below 190nm if necessary. The triple can be equipped with many different diffraction gratings and works fast as f/5.
For ultimate throughput, McPherson also offers the triple monochromator with astigmatic optics for point-to-point imaging.
