Its Light & Motion segment offers laser products, such as continuous wave and pulsed nanosecond, diode and diode-pumped solid-state, and fiber laser technologies; and photonics products comprising motion control, optical tables and vibration isolation systems, photonic instruments, optics and optical assemblies, opto-mechanical components, temperature sensing products for wafer fabrication systems, and laser and LED measurement products, including laser power and energy meters, laser beam profilers, and optical and photonic subsystems. Its Equipment & Solutions segment provides laser-based systems for printed circuit board (PCB) manufacturing, including flexible interconnect PCB processing systems and high-density interconnect solutions for rigid PCB manufacturing and substrate processing, and multi-layer ceramic capacitor test systems. It serves semiconductor, industrial technologies, life and health sciences, research, and defense markets. It sells its products and services through its direct sales organization, independent distributors, and sales representatives, as well as through its websites and product catalogs. The company was incorporated in 1961 and is headquartered in Andover, Massachusetts.

MKS Instruments was founded in 1961 as a provider of products and technologies used to measure, control, power, and monitor critical process parameters of advanced manufacturing processes.In 2001, the company acquired Emerson Electric's ENI Division which makes solid-state RF and DC plasma power supplies, networks and instruments.In April 2014, Brooks Automation entered into an agreement to sell its Granville-Phillips division to MKS Instruments. MKS Instruments more than doubled their addressable market by acquiring the Newport Corporation and its subsidiaries, including Ophir Optronics, for $980 million in a 2016 leveraged buyout. It acquired Electro Scientific Industries in 2019 and Atotech in 2021.In 2021, MKS Instruments had about 5,400 employees and a market capitalization of about $11 billion. As of 2021, sixty percent of the company's sales are from semiconductor products.
