Confocal laser microscope LEICA TCS SPE – this is a point scanning confocal system with a spectral detector for fluorescence registering the spatial structure of living and fixed objects. As the light source are lasers with high intensity and the monochromaticity of the radiation. The system consists of four solid-state laser with a wavelength of 405, 488, 532, and 635 nm. Confocal microscopy is widely used in the fields of biology, medicine, biophysics, molecular and cellular biology. It allows you to explore the tissue at the cellular level in a state of physiological activity.
