Optical Lenses

Optical lenses ndeye inojekesa zvinhu zvikamu zvine mavara akakomberedzwa anogona kuderedza uye kutarisa mwenje. Ivo vanoshandiswa zvakanyanya mune dzakasiyana-siyana masangano ekushandisa mwenje marara, kururamisa chiratidzo, kururamisa zvinhu, uye kugadzira mifananidzo. Lenses zvinhu zvakakosha muzvamakamera, terescopes, microscopes, maziso emaziso, majekiseni, uye mamwe mimwe mhandara yemidziyo.

Kune marudzi maviri makuru e lens:

Convex (kana kushandura) lenses. Convex Lenses inowanzoshandiswa mukukudza magirazi, makamera, uye eyeglasses kune chaiyo inofamba.

Concave (kana kutsauka) lenses. Svani dzinodzika dzinowanzoshandiswa pakururamisa nearsedness.

Lenses yakagadzirwa zvichienderana nehurefu hwemahure yavo, iyo iri kure kubva kune lens kune iyo focal point. Iyo yakareba yakareba inosarudza iyo degree rekukweretesa kwechiedza uye inokonzeresa mifananidzo yekuumbwa.

Mamwe mazwi akakosha ane hukama neye Optical lenses anosanganisira:

Focal Point. Kune convex lens, ndiyo pfungwa iyo ipo pakafanana ray converge. Kuti uwane renji renje, ndiyo pfungwa kubva kune iyo divergent mbambo dzinoonekwa kuti dzibve.

Kureba kwehurefu: Chinhambwe pakati pe lens uye iyo focal point. Iro parmeter rakakosha rinotsanangura simba re lens uye saizi yemifananidzo yakaumbwa.

Aperture: Iyo diamita ye lens inobvumira mwenje kuti ipfuure nepakati. Iyo yakakura kupararira inobvumira zvimwe mwenje kuti upfuure, zvichikonzera mufananidzo wakajeka.

Optical axis: Iyo Central mutsetse unopfuura nepakati peiyo lens perpendicular kumativi ayo.

Lens Simba: Yakayerwa muDiosters (d), Simba reLens rinoratidza kugona kwetsiva. Convex lenses ine masimba akanaka, nepo ma lenses ane masimba asina kunaka.

Optical lens Ivo vanoramba vachitamba basa rakakosha mukukwevera tekinoroji kufambira mberi uye kuongorora kwesainzi.
