IdealPhotonics' dispersion measurement system is a precision optical system used to quantitatively analyze the wavelength-dependent propagation characteristics (such as refractive index, group velocity delay, and phase delay) of optical signals or materials in the frequency or spatial domains.Through high-precision wavelength resolution technology, it quantitatively analyzes the differences in the propagation characteristics of light or materials at different wavelengths (such as group delay and refractive index), providing key dispersion parameters for the design and optimization of optical systems.
