MKS Instruments

MKS Instruments is a Massachusetts-based company headquartered in Andover that provides instruments, systems, and solutions for advanced manufacturing processes in semiconductor, industrial technologies, life sciences, and research markets. Following the acquisition of Newport Corporation, Spectra Physics lasers, and Photon Dynamics, MKS became a comprehensive provider of photonics, motion control, vacuum, and process management solutions. In research labs, MKS's Newport division is synonymous with optical components and motion control, supplying optical tables, translation stages, motorized rotation mounts, beam steering optics, and fiber optic components that are the backbone of custom optical setups. Spectra Physics lasers from MKS include the Tsunami Ti:Sapphire femtosecond oscillator, Spitfire ultrafast amplifiers, and the Millennia green pump laser, which are extensively used in ultrafast laser spectroscopy and multiphoton microscopy research. MKS's Granville-Phillips and InstruTech vacuum instruments, including Baratron capacitance manometers, ionization gauges, and mass flow controllers, are essential components in ultra-high vacuum surface science instruments, molecular beam epitaxy systems, and plasma processing chambers. Their pressure and flow control products are integrated into most semiconductor process tools. The company's power measurement instruments, including thermopile and photodetector-based power meters, are standard accessories in laser labs. MKS's Ophir division produces precision laser power and energy meters for research and industrial laser systems.
