Nhanganyaya yegirazi rekukudza, magnifier

Kana iwe uchida kuziva kuti chii agirazi rinokudzandizvo, ndapota verenga zvinotevera:

Girazi rinokudzachinhu chinoshandiswa kuona zvidiki-diki zvechinhu.Ilenzi rinotenderedza rine hurefu hwefocal idiki zvakanyanya pane inopenya daro reziso.Hukuru hwechinhu chinofananidzwa neretina yemunhu hunoenderana nekona yechinhu paziso (viewing angle).

Nhanganyaya pfupi:
Kukura kwekona yekuona, kunowedzera mufananidzo, uye kukwanisa kusiyanisa zvakadzama zvechinhu.Kuswedera pedyo nechinhu kunogona kuwedzera kona yekuona, asi inoganhurwa nekugona kwekutarisa kweziso.Shandisa agirazi rinokudzakuita kuti ive pedyo neziso, uye woisa chinhu chiri mukati mekutarisa kwacho kuti chigadzire mufananidzo chaiwo.Girazi rinokudza rinoshandiswa kukudza kona yekuona.Kubva kare, zvinonzi kushandiswa kwegirazi rinokudza kwakakurudzirwa naGrosstest, bhishopi weEngland muzana remakore rechi13.

Kare makore ane chiuru apfuura, vanhu vakagadzira makristasi akajeka kana kuti matombo anokosha anoonekera mu“lenzi", iyo inogona kukudza mifananidzo.Iyo inozivikanwawo seconvex lens.

Musimboti:
Kuti uone chinhu chidiki kana ruzivo rwechinhu zvakajeka, zvinodikanwa kutamisa chinhu pedyo neziso, izvo zvinogona kuwedzera kona yekuona uye kugadzira mufananidzo mukuru chaiwo paretina.Asi kana chinhu chacho chiri pedyo zvakanyanya neziso, hachikwanisi kunyatsoona.Mune mamwe mazwi, kuve unocherekedza, haufanirwe kungoita kuti chinhu chive nekona yakakura zvakakwana kune ziso, asi zvakare kutora chinhambwe chakakodzera.Zviripachena, kune maziso, izvi zviviri zvinodiwa zvinoganhurana.Kana iyo convex lens yakagadziriswa pamberi pemeso, dambudziko iri rinogona kugadziriswa.Convex lens ndiyo yakapfava girazi rekukudza.Icho chiri nyore optical chiridzwa chekubatsira ziso kuona zvinhu zvidiki kana ruzivo.Kutora convex lens semuenzaniso, simba rayo rekusimudzira rinoverengerwa.Isa chinhu PQ pakati pechinhu chinotariswa lenzi L nelenzi uye woita kuti ive pedyo nekutariswa, kuitira kuti chinhu chacho chigadzire mufananidzo wakakurisa wekuti p'Q 'kuburikidza nelenzi.Kana iyo mufananidzo square focal kureba kweconvex lens iri 10cm, simba rekukudza regirazi rinokudza rakagadzirwa nelens ka2.5, rakanyorwa se2.5 ×.Kana tikangofunga nezvesimba rekukudza, kureba kwacho kunofanirwa kunge kuri kupfupika, uye zvinoita sekunge chero simba guru rekukudza rinogona kuwanikwa.Nekudaro, nekuda kwekuvapo kwekukanganisa, simba rekusimudzira rinowanzoita 3 ×.girazi rinokudza(senge eyepiece) inoshandiswa, iyo aberration inogona kuderedzwa uye magnification anogona kusvika 20 ×.

Nzira yekushandisa:
Nzira yekucherechedza 1: rega girazi rinokudza pedyo nechinhu chakaonekwa, chinhu chakaonekwa hachifambi, uye chinhambwe chiri pakati peziso remunhu nechinhu chakaonekwa hachichinji, wobva wafambisa girazi rekukudza rinobata ruoko kumashure nekudzoka pakati pe chinhu uye ziso remunhu kusvikira chifananidzo chakura uye chakajeka.

Nzira yekucherechedza 2: girazi rinokudza richava pedyo nemeso sezvinobvira.Chengetedza girazi rekukudza richiripo uye fambisa chinhu kusvikira chifananidzo chakura uye chakajeka.

Chinangwa chikuru:
Inoshandiswa kuona mapepa uye kudhinda zvitoro zvemabhangi, matikiti, zvitambi, mari nemakadhi mune zvemari, mutero, philately uye zvemagetsi maindasitiri.Inogona kuziva uye nekukasira kuona mabhengi emanyepo ane high resolution.Kana chiedza chepepuru chinoonekwa chisina kururama, shandisa chiridzwa.

Inogona kunyatsozivikanwa.Iyo chaiyo RMB ine mitsetse yakajeka uye mitsetse yakabatana pasi pe microscope.Iwo mapatani emabhengi emanyepo anonyanya kuumbwa nemadoti, mitsara isingaenderere mberi, yakareruka ruvara, yakaoma uye isina-matatu-dimensional kunzwa.

Inoshandiswa muindasitiri yezvishongo, inogona kuona chimiro chemukati chematombo anokosha, kuyambuka-chikamu mamorekuru kurongeka, uye kuongorora uye kuona ore samples uye zvetsika zvisaririra.

Kune indasitiri yekudhinda, inogona kushandiswa kune yakanaka plate, kugadzirisa kwemavara, dot uye edge yekuwedzera yekutarisa, uye inogona kunyatso kuyera iyo mesh nhamba, dot size, overprint kukanganisa, nezvimwe.

Inoshandiswa muindasitiri yemachira, inogona kuona uye kuongorora machira efayibha uye warp uye weft density.

Inoshandiswa muindasitiri yemagetsi kuona mitsetse yenzira uye mhando yeakadhindwa redunhu bhodhi copper platinum board.

Inoshandiswa pakucherechedza uye Tsvagiridzo pabhakitiriya uye zvipembenene mune zvekurima, masango, zviyo uye mamwe madhipatimendi.

Inogona zvakare kushandiswa kumhuka nezvirimwa zvienzaniso, kuzivikanwa uye kuongororwa kwehumbowo nemadhipatimendi ekuchengetedza veruzhinji, tsvakiridzo yesainzi yekuyedza, nezvimwe.

Ndinokutendai nekuverenga kwenyu.Kana uchida rumwe rubatsiro, tapota taura nesu nemutsa.Ndatenda.
