Ultraviolet microscopy

    Ultraviolet microscopy makes it possible to solve a number of problems. First of all, increase the limiting resolution of the microscope by about two times as compared with the visible spectrum illumination, that is, reduce the limiting resolution of the microscope, which depends on the wavelength λ of the used radiation (for the UV rays used in microscopy λ = 400-200 nm while for the visible light λ = 680-400 nm). Second, reveal the structure of the specimens containing elements, which are transparent in the visible light but strongly absorb UV radiation of certain wavelength (typically these are components of plant and animal cells). And finally, observe the structure of the specimens containing particles that reflect UV spectrum rays differently than in the visible range (usually these are the majority of metals and minerals).

    Since ultraviolet rays are invisible to the human eye, the image is recorded with a special digital camera with an increased sensitivity in the UV range.
