Description:
Purpose: understand the microscopic structure. Optical microscope consists of an eyepiece, an objective lens, a coarse quasi-coke screw, a fine quasi-coke screw, a tabletting clip, a clear aperture, a shutter, a converter, a mirror, a stage, a mirror arm, a lens barrel, a mirror seat, a condenser and diaphragm
Experimental Report: dark-field microscopes do not project transparent light into the direct observation system. When there is no object, the dark field of view can not observe any object. When there is an object, light diffracted by the object and scattered light are in a dark background bright in the visible. In the dark field of view of objects, most of the illumination is folded back, due to the location of the object (specimen) structure, thickness, light scattering, refraction and there are great changes
Express Knowledge: it usually consists of optical parts, lighting parts and mechanical parts. The optical part is undoubtedly the most crucial, it consists of eyepiece and objective lens. As early as 1590, eyewear manufacturers in the Netherlands and Italy have created microscope-like magnifying devices. There are many types of optical microscopes, mainly bright field microscope (ordinary optical microscope), dark field microscope, fluorescence microscope, phase contrast microscope, laser scanning confocal microscope, polarized light microscope, differential interference microscope and inverted microscope
