Welcome to ToupTek
Fluorescence Microscope is a microscope used to observe fluorescent or phosphorescent substances. The principle of fluorescence microscopy is to use excitation light of a specific wavelength (or band ) to illuminate the sample. The excitation light is absorbed by the fluorophore and emits emitted light with a longer wavelength. The emission filter can be used to separate the emitted light from the excitation light. The emitted light is irradiated onto the detector to achieve fluorescence imaging. In recent years, fluorescence microscopy systems have been widely used in biological research, such as observing fluorescently labeled biomolecules, which makes fluorescence microscopy increasingly important.

Dimensional diagram of FM100 series fluorescence microscope system
Biomedical field applications
In the field of biomedicine, fluorescent dyes are mainly used to label samples, so that cells and submicroscopic cellular components can be accurately and detailedly identified under a fluorescence microscope. Figure 2 shows an image of BPAE cells stained with DAPI fluorophore and captured using an FM100 series microscope system.
Figure 2 FM100 series microscope system (10X objective lens) captures BPAE cells (365 nm excitation light)
Paper industry applications
Figure 3 shows an image of paper taken using an FM100 series fluorescence microscope. Under 365nm excitation light, the bleach in the paper is clearly imaged, but the presence of the bleach cannot be observed with the naked eye.
