Excitation wavelength

Excitation wavelength classification is based on the wavelength range in which the fluorescent probe is excited by the light source, including Ex <400 nm (ultraviolet excitation), Ex 400-430 nm (violet excitation), Ex 431-450 nm (blue excitation), Ex 451-570 nm (green excitation), Ex 571-600 nm (yellow excitation), Ex 601-630 nm (orange excitation), Ex 631-760 nm (red excitation) and Ex >761 nm (near infrared excitation). These specific wavelength ranges ensure efficient excitation for different markers, enabling fluorescent probes to provide specific labeling and detection in a variety of biological applications. In short, according to the different excitation wavelengths, fluorescent probes are subdivided into multiple intervals from ultraviolet to near infrared to meet the precise excitation requirements for various biological research and diagnostic needs.
