Microscope optical tsarin - abubuwa
Abubuwa ne muhimmin sashi na ƙayyade microscope aiki, shigar a kan abu mai juyawa, kusa da abu da aka lura, don haka ake kira abu ko dauki abu

AbubuwanYana da muhimmin sassa na ƙayyade aikin microscope, shigar da shi a kan mai canzawa na abu, kusa da abubuwan da ake lura da su, don haka ana kiran abu ko abubuwan da ake ɗaukar su. http://www.shhx17.com/shhx17/com_pro.asp
1, rarraba abubuwa
Abubuwan da za a iya raba su zuwa bushewa abubuwa da kuma immersion abubuwa dangane da yanayin amfani daban-daban;
Wannan immersion abubuwa kuma za a iya raba su zuwa ruwa immersion abubuwa da kuma man fetur immersion abubuwa (sau da yawa amfani da amplification multiples ne 90)—100 daga cikinsu.
Wannan immersion abubuwa kuma za a iya raba su zuwa ruwa immersion abubuwa da kuma man fetur immersion abubuwa (sau da yawa amfani da amplification multiples ne 90)—100 daga cikinsu.
Za a iya raba shi zuwa ƙananan abubuwa bisa ga daban-daban na amplification multiples (10sau kasa), matsakaici sau abu(20sau da kimanin), mafi girma sau da abu(40—65 daga cikinsu.
Dangane da bambancin daidaitawa, an raba shi zuwa bambancin launi na launi (wanda aka saba amfani da shi, wanda zai iya gyara bambancin launi na launi guda biyu a cikin spectrum) da bambancin launi na launi (wanda zai iya gyara bambancin launi na launi uku a cikin spectrum, farashi mai tsada, amfani da ƙasa).
2, babban sigogi na abu:
Manyan sigogi na abubuwan da aka yi amfani da su sun haɗa da: ƙarin girma, ƙididdigar ƙididdiga, da nesa na aiki.
①Ƙara yawaYana nufin daidaitaccen girman da idanu suka gani da girman samfurin. Yana nufin rabo na tsawo maimakon rabo na yanki. Misali: Ƙarin girma 100x, yana nufin tsawon ne1μmtsawon samfurin, bayan zoom image ne100μmIdan an lissafa shi da yanki, an haɓaka shi10,000 daga cikinsu.
Jimlar ƙarfin ƙarfin microscope daidai ne da ƙarfin ƙarfin ƙarfin abu da kuma talauci.
②Lambar aperture kuma ake kira madubi ƙimarda takamaiman nakoA, shi ne babban sigogi na abubuwan da kuma focuser, daidai da ƙuduri na microscope. The lambar aperture na bushewa abu ne0.05-0.95The lambar aperture na man fetur ruwan ruwa (cedar man fetur) ne1 ƙa.
②Aiki nesaYana nufin nesa a ƙasa da ruwan tabarau na gaba na abu zuwa sama da samfurin rufin samfurin lokacin da samfurin da aka lura ya bayyana. Aikin nesa na abu yana da alaƙa da nesa na abu, mafi tsawo nesa na abu / mafi ƙasƙanci / mafi tsawo nesa na aiki.

3. Matsayin abuWannan shine farkon girma samfurin, kuma shine muhimmin ɓangare na ƙayyade aikin microscope - ƙarancin ƙuduri.
Hakanan ana kira ƙuduri ko ƙuduri. An nuna girman ƙuduri ta hanyar ƙididdigar nesa (mafi ƙarancin nesa tsakanin abubuwa biyu da za a iya bambanta su). A bayyane gani nesa (25cm)(A wuri, al'ada mutum idanu iya ganin nesa)0.073mmBiyu abubuwa, wannanDarajar 0.073mm, wato, nesa na al'ada na ido na mutum. Mafi ƙarancin nisan ƙuduri na microscope, watau, mafi girman ƙudurinsa, watau, mafi kyawun aikinsa.
Girman ƙudurin microscope yana ƙayyade ta hanyar ƙudurin abu, kuma ƙudurin abu yana ƙayyade ta hanyar ƙididdigar ƙididdigarsa da tsawon raƙuman hasken haske.
Lokacin da aka yi amfani da na yau da kullun tsakiyar haske (sa haske daidai ta hanyar haske na samfurin), ƙuduri nesa na microscope ne d = 0.61λ/NA
Tsarin D- ƙuduri nesa na abubuwa, naúrar nm
λ - Hasken haske wavelength, naúrar nm
λ - Hasken haske wavelength, naúrar nm
NA- lambar aperture na abu
Alal misali, lambar aperture na man fetur abu ne1.25, bayyanar haske wavelengths kewayon ne400—700nm, dauki da matsakaicin wavelength550 nmSa'an nand=270 nm, daidai da kusan rabin wavelength haske.Gabaɗaya, iyakar ƙuduri na microscope tare da haske mai gani shine0.2μm。
