Leading-Edge Solutions for Accurate Optical Measurements
Light is understood through measurement of its spectrum, wavelength, power, and reflections. Yokogawa’s optical instruments capture these properties with high precision, helping engineers and researchers understand how light behaves in real systems.
- Resolve optical spectra to observe mode structure, noise floor, and sidebands.
- Track wavelength accuracy and drift in tunable or stabilized sources.
- Characterize reflection, scattering, and loss in fibers and optical components.
- Measure absolute and relative optical power across wide dynamic ranges.
- Build integrated test systems with light source, switches, attenuators, SMUs, and OPMs to evaluate photonic subsystems.
