Multimodal nonlinear optical (NLO) imaging is a microscopy approach used in a variety of biomedical applications. It harnesses and integrates the unique capabilities of nonlinear processes such as multiphoton fluorescence, second- and third-harmonic generation (SHG and THG), and coherent Raman scattering (CRS) and combines them seamlessly into a single, unified microscopy platform.

594-nm laser excitation can enhance our ability to analyze cells by flow cytometry. This laser wavelength fills a significant excitation gap between the now common 561-nm line and the red laser sources. Adding this wavelength to the excitation repertoire enables excitation of virtually any visible fluorescent probe for cytometric analysis. Learn More
