WebFeb 1, 2024 · For example, if the excitation wavelength a fluorophore is 350 nm (UV rays), in two-photon microscopy this is achieved by using two photons with double the wavelength, i.e. 700 nm. To achieve excitation, both the photons should reach the fluorophore at the same time or within s10X e-18 of each other. Design of the microscope WebFeb 17, 2024 · photon, also called light quantum, minute energy packet of electromagnetic radiation. The concept originated (1905) in Albert Einstein’s explanation of the photoelectric effect, in which he proposed the existence of discrete energy packets during the transmission of light. Earlier (1900), the German physicist Max Planck had prepared the …
