McPherson designs and manufactures monochromators, spectrometers and related optical system solutions for scientific measurement and sensing applications. Weve shipped thousands of instruments worldwide for scientific research, development, and industrial process applications. Our customer list reads like "Who's Who". The most respected research laboratories utilize our systems and publish data obtained with the help of our instruments; instruments that range from miniature spectrometers flown into space or fit into pockets, to versions that weigh 20 tons and span 30 meters. The broad use of our products has given us great strength and depth. Our robust, high performance instruments measure molecular and atomic spectra in the long wave infrared, UV-Visible, vacuum ultraviolet, and even the soft x-ray wavelengths as short as one nanometer. We also develop with and for you! We invite your inquiries for scientific instruments and systems that solve specific analytical challenges.
