Plano-concave lo ntsiab muag PDF Daim Duab

Qhov muag muag muag yog pob tshab kho qhov muag nrog nkhaus uas muaj peev xwm ua kom pom kev. Lawv tau siv dav hauv ntau qhov kev kho qhov muag rau tswj lub teeb ci, kho lub zeem muag, khoom siv ua kom loj, thiab sib sau cov duab. Lo ntsiab muag yog cov ntsiab lus tseem ceeb hauv cov koob yees duab, tsom iav, tsom iav, tsom iav, cov tswv cuab, thiab lwm yam khoom siv kho tshiab.

Muaj ob lub ntsiab ntawm lo ntsiab muag:

Convex (lossis converging) lo ntsiab muag: Cov ntsiab lus no yog thicker ntawm lub chaw tshaj li ntawm cov npoo, thiab lawv txuas kom sib haum lub teeb ci ntsa iab uas dhau los ntawm lawv mus rau lub hauv paus ntsiab lus ntawm lub lens. Tus lo ntsiab muag tau siv nyob rau hauv lub tsom iav tsom iav, cov koob yees duab, thiab tsom iav kom kho kom raug.

Concave (lossis diverging) lo ntsiab muag: Cov iav lo ntsiab muag yog thinner ntawm lub chaw tshaj li ntawm cov npoo, thiab lawv ua kom sib haum raws li yog lawv los ntawm lub focal focal point ntawm tib lub lens. Concave lo ntsiab muag feem ntau siv nyob rau hauv kev kho ze ze.

Lo ntsiab lus yog tsim raws li lawv lub focal ntev, uas yog qhov kev ncua deb ntawm lub lens rau lub focal point. Lub focal ntev txiav txim siab cov qib ntawm lub teeb ntawm kev khoov thiab cov duab tsim duab.

Qee cov ntsiab lus tseem ceeb ntsig txog cov iav lo ntsiab muag pom muaj xws li:

Focal point: Qhov taw tes uas lub teeb ci ntsa iab los yog tshwm rau diverge tom qab dhau los ntawm lub lens. Rau lub convex lub lens, nws yog qhov uas thaum uas sib txuas sib dhos. Rau ib qho concave lens, nws yog qhov taw tes los ntawm cov divergent rays pom los ua los.

Focal ntev: Qhov kev ncua deb ntawm lub lens thiab lub focal point. Nws yog ib qho chaw tseem ceeb uas txhais tau lub lens lub zog thiab qhov loj ntawm cov duab tsim.

Lub tsev txwv: Txoj kab uas hla ntawm lub lens uas tso cai rau lub teeb kom dhau los. Ib qhov loj dua qub theej tso cai rau ntau dua, ua rau muaj cov duab ntse dua.

Aptical Axis: Lub hauv paus kab uas hla dhau ntawm nruab nrab ntawm lub lens txiav nws cov chaw.

Lens Hwjchim: Ntsuas hauv Diopters (d), lub lens hluav taws xob qhia tau lub peev xwm tshiab ntawm lub lens. Cov ntsiab muag Convex muaj lub hwj chim zoo, thaum concave lo ntsiab muaj lub peev xwm tsis zoo.

Kev siv kho qhov muag tau muaj kev hloov kho ntau yam, los ntawm kev ua haujlwm hauv tsev kho mob uas nyob deb, thiab ua kom pom tseeb kev xav thiab ntsuas. Lawv txuas ntxiv mus ua si ib lub luag haujlwm tseem ceeb hauv kev nce qib thev naus laus zis thiab kev tshawb nrhiav kev muaj keeb kev tshawb fawb.
