McPherson Inc. is a well-established American manufacturer of precision optical instruments, founded in 1953 and headquartered in Chelmsford, Massachusetts. With over 70 years of experience, the company specializes in the design, production, and support of high-performance spectrometers, monochromators, spectrographs, and custom optical systems for demanding scientific and industrial applications.
The company is particularly renowned for its expertise across challenging spectral ranges – from soft X‑ray (SXR) and extreme ultraviolet (EUV) through vacuum ultraviolet (VUV) and deep ultraviolet (DUV) to long‑wave infrared (LWIR). Their instruments operate from wavelengths below 1 nm up to 20 µm, with some systems offering picometer‑level resolution. McPherson also certifies components for high and ultra‑high vacuum (UHV) environments, including helium leak testing and RGA certification.
Key products include Czerny‑Turner and Seya‑Namioka monochromators, normal‑incidence spectrometers, and VUVAS series spectrophotometry systems for measuring absolute transmission, reflectance, and absorption. Accessories such as detectors, fiber optics, filter wheels, and telescopes complement the core offerings.
McPherson instruments serve a wide range of markets: semiconductor metrology (EUV), plasma diagnostics, quantum science, high‑harmonic generation (HHG) laser characterization, aerospace (space‑borne spectrometers), and optical coating characterization for filters, crystals, and thin films. As a privately held, US‑based company, McPherson is known for its quality, precision, and ability to deliver fully customized solutions tailored to specific customer requirements.
