Description

Technical Field

[0001] The utility model relates to the technical field of microscopes, in particular to an oil dropping device for a microscope. Background Art

[0002] A microscope is an optical instrument composed of a lens or a combination of several lenses. A microscope is mainly used to magnify tiny objects so that they can be seen by the naked eye. In order to reduce the scattering of light during microscopic observation and achieve the purpose of reducing chromatic aberration, immersion oil is used. Microscope immersion oil is the oil dripped on the slice when observing the slice with an oil immersion lens. When observing, immersion oil is dripped between the oil-immersion objective lens and the coverslip. Using immersion oil as the observation medium can reduce the scattering of light and achieve the purpose of reducing chromatic aberration.

[0003] When dripping lens oil on an existing microscope, the user holds a lens oil bottle and drips the lens oil on the surface of the slide. However, in this way, the user needs to find or equip the lens oil bottle every time the microscope is used, which makes it inconvenient to drip oil. Therefore, we propose a microscope oil dripping device to solve the above problem. Utility Model Content
