McPherson is a custom manufacturer of precision optical instruments and systems for measuring and characterizing spectra. McPherson instruments measure intensity vs. frequency in various regions of the electromagnetic spectrum. McPherson’s spectral test instruments are based on the dispersing properties of a diffraction grating and/or refractive prism. McPherson specializes in vacuum fabrication, ultraviolet optical systems, spectroscopic technique, and high resolution spectral test and measurement instrumentation. End-user and OEM applications include research, metrology, semiconductors, pharmaceuticals, nanotechnology, aerospace and defense. ==History== McPherson began manufacturing spectral test instrumentation in 19521. The company's first spectral test instruments were rocket born spectrometers used outside the earth’s atmosphere to study the vacuum ultraviolet portion of the solar spectrum. Today, McPherson instruments are employed in laboratory environments around the world, for spectroscopic analysis in the infrared, visible, vacuum ultraviolet, and soft x-ray regions.
