Optical test equipment or optical measurement equipment are used to measure and characterize the physical properties of light. The insatiable demand for higher capacity in communication networks has fueled the need for highly precise optical test solutions. In addition, precision optical measurements are essential to optical research applications for biophotonics, environmental sensing, and consumer products.

R&D engineers, academic researchers, manufacturing engineers, and field service personnel depend on precision optical test equipment to ensure design and performance specifications, production quality, and network health. For more than thirty years, Yokogawa (formerly Ando) has delivered quality, consistency, ease of use, and market leadership for optical test applications.
