McPherson makes monochromators and spectrometers as well as optical systems for spectroscopy.

We design, assemble and test instrumentation for many wavelengths; from soft x-ray and extreme ultraviolet, through vacuum ultraviolet and UV-Visible, and up to the long wave infrared. Our systems work in many applications and many science disciplines. We offer imaging spectrometers for high temperature plasma physics, Raman systems for physical-chemistry, HPLC fluorescence detectors for pharma, spectral calibration stations for astrophysics, and several types of spectrophotometers for material characterization. Ours is a product line complete with accessories for those who do it themselves. We offer light sources, detectors, filter wheels, specialty filters, fiber optics, telescopes, and collimators. Most of these are also available for vacuum and ultra high vacuum applications. 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. We also develop with and for you! We invite your inquiries for scientific instruments and systems that solve specific analytical challenges.

What’s new

  • soft x ray spectrometer

    SXR monochromator works 3 different ways

    Products | 3 May 2018

    Direct detection CCD detectors and open microchannel plate intensifiers fit. Extreme ultraviolet hollow cathode and solid-anode electron impact light sources do too. They are useful for calibration and spectral test applications and set this instrument apart from others.

    What can you learn with McPherson?

    News | 9 Mar 2018

    McPherson is pleased to announce the spring 2018 hands-on learning session.

  • 629 axial view of plasma

    High-energy UV lamp

    Products | 4 Aug 2017

    McPherson is pleased to announce new and improved stability with flow controlled McPherson windowless, hollow cathode UV lamp Model 629. This broad-spectrum source emits ionized gas emission lines with little or no absorption by neutral gas. Computer controlled gas flow and constant current power supply improve stability for better spectroscopy.

    Amplifier on Vacuum-safe Ceramic Board

    Products | 22 Apr 2016

    McPherson VUV series photodiodes are used for the detection of UV, EUV and x-ray (wavelength range 1100 nm to .124 nm, energy range 1.13 eV to 1 keV) photons. Unlike common p-n junction diodes, the photodiodes do not have a doped dead-region and have zero surface recombination.

  • Sensor Spectral Test and Calibration

    Products | 8 Dec 2015

    The McPherson Spectral Test Station (STS) is for wavelength testing and calibration from LWIR to 200 nanometers and less. It is for sensor testing, process control, and calibration. It also works for ground-based calibration of flight sensors.
