Mitä ovat tärkeimmät sovellukset optiset mikroskoopit sisään

Optical microscope is an ancient and young scientific tool that has a history of 300 years since its birth. Its applications are very extensive, such as in biology, chemistry, physics, astronomy, and other scientific research work.

At nykyinen, it on melkein tullut kuva tiedottaja tieteelle ja teknologialle. Sinä vain tarve nähdä sen usein esiintyminen mediassa raportit tietoja tieteestä ja teknologia nähdä että tämä väite on myös totta.

In biologia, laboratoriot ei voi tehdä ilman tällainen kokeellinen välineet, mikä voi auttaa oppijat tutkia tuntematon maailma; saada tietää maailma.

Traditional optical microscopes are mainly composed of optical systems and the mechanical structures that support them. The optical systems include objective lenses, eyepieces, and condenser lenses, all of which are complex magnifying glasses made of various optical glasses. The objective lens magnifies the specimen for imaging, and its magnification, M object, is determined by the following equation: M object= Δ∕ F 'object, where f' object is the focal length of the objective lens, Δ It can be understood as the distance between the objective lens and the eyepiece. The eyepiece magnifies the image formed by the objective lens again, forming a virtual image for observation at a distance of 250mm in front of the human eye. This is a comfortable observation position for most people. The magnification of the eyepiece is M mesh=250/f 'mesh, where f' mesh is the focal length of the eyepiece. The total magnification of a microscope is the product of the objective and eyepiece, i.e. M=M object * M mesh= Δ* 250/f 'mesh * f; Things. It can be seen that reducing the focal length of the objective and eyepiece will increase the overall magnification, which is the key to using a microscope to see bacteria and other microorganisms, and also the difference between it and a regular magnifying glass.
