Plano-Concave Lenses PDF Drawing

Optical lo ntsiab muag yog pob tshab optical Cheebtsam nrog cov npoo nkhaus uas tuaj yeem thim rov qab thiab tsom lub teeb.Lawv tau siv dav hauv ntau lub tshuab kho qhov muag los tswj lub teeb rays, kho qhov muag pom, nthuav cov khoom, thiab tsim cov duab.Lenses yog cov khoom tseem ceeb hauv lub koob yees duab, telescopes, microscopes, tsom iav, projectors, thiab ntau lwm yam khoom siv kho qhov muag.

Muaj ob hom lenses tseem ceeb:

Convex (los yog converging) lo ntsiab muag: Cov lo ntsiab muag no yog thicker ntawm qhov chaw tshaj ntawm cov npoo, thiab lawv converge lub teeb nyob rau tib lub teeb rays uas dhau los ntawm lawv mus rau ib tug focal point ntawm opposite sab ntawm lub lens.Convex lo ntsiab muag feem ntau yog siv rau hauv tsom iav tsom iav, koob yees duab, thiab tsom iav tsom iav kom kho qhov pom kev deb.

Concave (los yog diverging) lo ntsiab muag: Cov lo ntsiab muag no nyias nyias ntawm qhov chaw tshaj li ntawm cov npoo, thiab lawv ua rau lub teeb sib luag ntawm lub teeb ci dhau los ntawm lawv mus rau diverge zoo li lawv tuaj ntawm qhov chaw focal virtual ntawm tib sab ntawm lub lens.Concave lo ntsiab muag feem ntau siv los kho qhov ze ze.

Lenses yog tsim los ntawm lawv qhov ntev focal, uas yog qhov deb ntawm lub lens mus rau qhov chaw focal.Lub focal ntev txiav txim siab qhov degree ntawm lub teeb khoov thiab cov duab tsim.

Qee cov ntsiab lus tseem ceeb ntsig txog cov lo ntsiab muag kho qhov muag muaj xws li:

Focal point: Lub ntsiab lus uas lub teeb rays converge los yog tshwm sim diverge tom qab dhau los ntawm ib lub lens.Rau lub lens convex, nws yog qhov chaw uas cov kab hluav taws xob sib txuas sib txuas.Rau lub lens concave, nws yog qhov taw qhia los ntawm qhov sib txawv rays tshwm tuaj.

Focal ntev: Qhov kev ncua deb ntawm lub lens thiab lub focal point.Nws yog ib qho tseem ceeb parameter uas txhais lub lens lub hwj chim thiab qhov loj ntawm daim duab tsim.

Aperture: Txoj kab uas hla ntawm lub lens uas tso cai rau lub teeb hla.Lub aperture loj dua tso cai rau lub teeb kom dhau mus, ua rau cov duab ci dua.

Optical axis: Txoj kab nruab nrab hla dhau qhov nruab nrab ntawm lub lens perpendicular rau nws qhov chaw.

Lens zog: Ntsuas hauv diopters (D), lub hwj chim ntawm lub lens qhia txog lub peev xwm refractive ntawm lub lens.Convex lo ntsiab muag muaj lub zog zoo, thaum lo ntsiab muag concave muaj lub zog tsis zoo.

Cov lo ntsiab muag kho qhov muag tau hloov pauv ntau yam, los ntawm astronomy mus rau kev tshawb fawb kho mob, los ntawm kev tso cai rau peb saib cov khoom nyob deb, kho teeb meem tsis pom kev, thiab ua cov duab meej thiab ntsuas.Lawv txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev nce qib thev naus laus zis thiab tshawb nrhiav kev tshawb fawb.
