Multiplex nonlinear Raman imaging enhances weak Raman scattering and obtains broadband spectra for molecular spectroscopic imaging. However, a supercontinuum light source causes chromatic aberration when using a high numerical aperture objective, resulting in a missing part of the spectrum. Here, we utilized Bessel beam illumination to compensate for the chromatic aberration.
