WebTwo-photon microscopes use infrared excitation light to penetrate further into tissues and with minimal scatter compared to exciting at longer wavelengths. For each excitation of the fluorophore, two photons of infrared light are absorbed, and excitation is limited to a tiny focus volume, so there is less contribution from out-of-focus fluorescence. law offices of michael b brehne
