McPherson unveiled a new compact, double monochromator on Tuesday that may aid in the detection of chemical, biological, radiological, nuclear or explosive (CBRNe) threats.
The McPherson Model 275DS device utilizes the Standoff Raman spectroscopy technique to be able to analyze a large area within minutes. Raman spectroscopy is often utilized in chemistry to observe different phenomena that are difficult or impossible to do detect without specific instruments. It uses a single monochromatic light affecting energy of the individual photons.
McPherson's monochromator is able to garner results utilizing wavelengths of light as short as 190 nanometers without the need for additional preparation. The monochromator has a controller available that allows different wavelengths of light and precision in accuracy to be determined by the user for what is needed.
The monochromator includes bandwidth apertures sizes up to XXL, which allow for a wider range of spectra data to be collected.
McPherson specializes in the manufacturing of optical instruments that allow measurements and tuning of light wavelengths in order to provide accurate data for the field of optical spectroscopy.
The McPherson Model 275D monochromator joins other products on the market that are meant to be used to create a sensing network for early detection of CBRNe threats.
