Malenzi eOptical zvinhu zvinoonekera zvinoonekera zvine curved surfaces izvo zvinokwanisa kureruka uye kutarisa chiedza. Iwo anoshandiswa zvakanyanya muakasiyana-siyana optical masisitimu kushandura mwaranzi yemwenje, kugadzirisa chiono, kukudza zvinhu, uye kugadzira mifananidzo. Malenzi zvinhu zvakakosha mumakamera, teresikopu, maikorosikopu, magirazi emaziso, mapurojekita, uye zvimwe zvakawanda zvinoona michina.

Kune marudzi maviri makuru emalenzi:

Convex (kana converging) lenzi: Malenzi aya akakora nechepakati pane ari kumacheto, uye anochinjisa maranzi emwenje anofambirana anodarika nemaari kusvika panzvimbo yakatarisana nerumwe rutivi rwelenzi. Maconvex lenzi anowanzoshandiswa mukukudza magirazi, makamera, uye magirazi emaziso kugadzirisa kuona zviri kure.

Concave (kana diverging) lenzi: Malenzi aya akatetepa nechepakati pane ari kumacheto, uye anoita kuti mirazvo yemwenje inofambirana inopfuura nepakati pawo isiyane sekunge iri kubva panzvimbo yakatariswa iri kudivi rimwe chete relenzi. Concave lenses anowanzo shandiswa mukururamisa kuona pedyo.

Malenzi akagadzirwa zvichienderana nehurefu hwawo hwekutarisa, inova chinhambwe kubva palenzi kusvika pakatarisana. Hurefu hwekutarisa hunotaridza mwero wekupeta kwechiedza uye mhedzisiro yemufananidzo.

Mamwe mazwi akakosha ane hukama neoptical lenses anosanganisira:

Focal point: Nzvimbo iyo maranzi emwenje anosanganidzana kana kuita seanosiyana mushure mekupfuura nepalenzi. Kune convex lens, ndiyo nzvimbo inosanganidzana miranzi. Kune iyo concave lens, ndiyo nzvimbo iyo maranzi akasiyana anoita seanotangira.

Urefu hwekutarisa: Chinhambwe chiri pakati pelenzi nenzvimbo yakatarisa. Iyo yakakosha parameter inotsanangura simba re lens uye saizi yemufananidzo wakaumbwa.

Aperture: The dhayamita ye lens inobvumira chiedza kupfuura. A aperture hombe inobvumira chiedza chakawanda kupfuura, zvichiita kuti pave nemufananidzo wakajeka.

Optical axis: Mutsara wepakati unopfuura nepakati pe lens perpendicular kune nzvimbo dzayo.

Lens simba: Yakayerwa mu diopters (D), iyo lens simba rinoratidza kugona refractive kwelens. Maconvex lenzi ane masimba akanaka, nepo concave lenzi ane masimba asina kunaka.

Malenzi emaziso akachinja zvinhu zvakasiyana-siyana, kubva pakuongorora nyeredzi kuenda kusayenzi yezvokurapa, nokutibvumira kuona zvinhu zviri kure, kugadzirisa matambudziko ekuona, uye kuita kufungidzira uye kuyerwa chaiko. Vanoramba vachiita basa rinokosha mukufambisira mberi ruzivo rwokugadzira zvinhu uye kuongorora kwesayenzi.
