Description

Technical Field

[0001] The utility model relates to the field of confocal laser microscopes, in particular to an animal and plant sample clamping device for a confocal laser microscope. Background Art

[0002] Confocal means that the light path (excitation and emission) is focused at two positions. In the confocal scanner, the excitation light is focused on the surface of the sample point, while the emission light is focused on the pinhole. This pinhole limits the focusing depth of the instrument on the sample surface, effectively preventing background noise interference caused by impurity signals (such as dust fluorescence, contamination on the back of the sample, fluorescence signals from glass, common dust particles in the air, and fluorescence contamination from the optical components of the scanner), thereby reducing the intensity of the background signal. The confocal laser microscope is an analytical instrument used in the fields of biology, pharmacy, traditional Chinese medicine and traditional Chinese medicine.

[0003] A microscope is an optical instrument composed of a lens or a combination of several lenses. It is a symbol of mankind's entry into the atomic age. Microscopes are mainly used to magnify tiny objects so that they can be seen by the naked eye. Microscopes are divided into optical microscopes and electron microscopes. The optical microscope was first invented by Janssen of the Netherlands in 1590. Today's optical microscopes can magnify objects 1600 times, and the minimum resolution limit is 1 / 2 of the wavelength. The length of the mechanical tube of domestic microscopes is generally 160 mm.
