Mksinst

The company's hardware portfolio spans several major divisions. It includes vacuum and gas measurement tools, Spectra-Physics lasers (acquired in 2016), and a wide range of photonics, infrared optics, and laser measurement equipment marketed globally under the Ophir brand.

The company operates as a hardware and chemical component supplier in the global semiconductor manufacturing landscape. It has expanded its footprint through acquisitions, completing the purchase of Newport Corporation in 2016 and acquiring the specialty chemicals firm Atotech in 2022. These transactions diversified MKS into advanced optics, photonics, and printed circuit board (PCB) manufacturing chemistry.

The Israeli operations of MKS Instruments are anchored by the legacy Ophir Optronics facility in Jerusalem. The local site handles the research, development, and manufacturing of infrared optical components and laser measurement systems. Teams in Israel include optics engineers, mechanical engineers, electronics developers, and production staff operating dedicated manufacturing lines.
