For over 100 years, the Yokogawa family of companies have been pioneers in the development of measurement solutions that enable R&D teams to efficiently and effectively gain the best insights from their measurement strategies. 

Inspired by the belief that precise, accurate, and reliable measurement lies at the heart of successful innovation, the Precision Makers of the Yokogawa Test&Measurement (Yokogawa T&M) business division endeavor to provide researchers and engineering professionals with the tools and solutions needed to address their optical test and measurement applications and workflow challenges great and small.

Yokogawa T&M instruments are globally-renowned for high levels of precision, quality, service support, durability, and for delivering value far longer than is typical of optical testing equipment. Our OSA lineup delivers superior resolution, sensitivity, and dynamic range compared to competing technologies, covers regions SWIR (1200-2400nm, 1000-2500nm) through MWIR (1500-2400nm, 1900-5500nm), and includes the world’s first (and only) grating-based OSA that measures to 5.5µm. Our expansive optical test and measurement solutions also include multiwavelength meters, optical time domain reflectometers, component analyzers, tunable laser sources, multimeters, light sources, and modular manufacturing test systems.
