Magirazi ekuongorora mutsarainoumba chikamu chakakosha chehurongwa hwekuona kwemuchina. Kusarudzwa kwavo ibasa rine mativi akawanda, rakarongeka—uye zvechokwadi danho rinokosha—rinoda kuongororwa kwakazara kwekuenderana kwezvinhu zvakasiyana-siyana, kusanganisira sisitimu yese yekutarisa mifananidzo, mamiriro chaiwo ekushandiswa, uye mamiriro ekunze.
Pakazara, zvinotevera ndizvo zvinhu zvakakosha pakusarudza lenzi yekutarisa mutsara:
1.Magadzirirwo emukati emaziso
(1)Kugadziriswa: Kugadziriswa kwelenzi kunoreva kugona kwelenzi kugadzirisa zvinhu zvidiki; inofanira kuenzaniswa nehukuru hwemapikiseli ekamera uye inowanzoda kudarika huwandu hwemapikiseli ekamera kuitira kuti ive nechokwadi chekuti saizi shoma yekuona inoonekwa. Kuti uwane mhando yepamusoro yemufananidzo, zvinowanzodiwa kusarudza lenzi ine resolution yepamusoro; kana lenzi ine resolution yakaderera ikasarudzwa, mabhenefiti anopiwa nenhamba yepamusoro yemapikiseli ekamera haagone kuonekwa zvizere.
(2)Kureba kweFocal: Kureba kwefocal kwelenzi kunoshanda sechinobatanidza daro rekushanda, nzvimbo yekuona, uye saizi yesensor; ndicho chinhu chikuru chinosarudza kukura kwemifananidzo uye chinokanganisa marongerwo enzvimbo uye kureba kwenzira ye optical yesystem. Kureba kwefocal kwenguva refu kunoita kuti pave nekukura kwakanyanya uye nzvimbo diki yekuona, zvichiita kuti ive yakakodzera kuongorora zvinhu zvidiki kana kuti kune maapplication anoda kukura kwakanyanya; zvakasiyana, kureba kwefocal kwenguva pfupi kunoita kuti pave nekukura kwakaderera uye nzvimbo yakakura yekuona, zvichiita kuti ive yakakodzera kuongorora zvinhu zvine fomati yakakura.
(3)Aperture uyedchikamu chefmunda: Saizi yeAperture inokanganisa huwandu hwechiedza chinopinda mumufananidzo uye kudzika kwemunda. Aperture yakafara yakakodzera nzvimbo dzisina chiedza chakawanda, kunyangwe zvingangouya nekudzika kwemunda; Kusiyana neizvi, aperture yakamanikana inowedzera kudzika kwemunda asi inoda kupenya kwakasimba. Kazhinji, zvinhu zvine nzvimbo dzisina kurongeka zvinoda kudzika kukuru kwemunda, zvichida kuenzana kwakanyatsonaka pakati pehukuru hweaperture nenguva yekuratidzwa; zvisinei, pakutora mifananidzo yezvinhu zvinofamba nekukurumidza kana muzvirongwa zvinoda nguva pfupi yekuratidzwa, lenzi yeaperture yakafara inofanira kusarudzwa kuti iwedzere kupenya kwemufananidzo.
Aperture ndiyo chinhu chakakosha pakuongorora malenzi emutsetse
(4)Nzvimbo yekuona uye daro rekushanda: Nzvimbo yekuona inotariswa nehurefu hwenzvimbo yacholenziuye kureba kwesensa yekamera. Nzvimbo yakakodzera yekuona inofanirwa kusarudzwa zvichienderana nehukuru hwenzvimbo yekupfura. Semuenzaniso, pakupfura zvinhu zvikuru, lenzi ine nzvimbo yakakura yekuona inofanira kusarudzwa. Nhambwe yekushanda inotarwa nekugadzirwa kwechimiro chemuchina; zvakakosha kutsanangura huwandu hunodiwa hwenzvimbo dzekushanda uye, mushure mezvo, kusarudza lenzi inowira mukati meiyi nzvimbo chaiyo zvichienderana nenhambwe chaiyo iri pakati pelenzi nechinhu chiri kushandiswa.
2.Zvinhu zvemakanika uye zvekuisa
Chekutanga uye chakakosha, lenzi yemutsara yakasarudzwa inofanira kunge inoenderana nehukuru hwesensa yekamera; izvi zvinoita kuti lenzi ikwanise kushandisa zvizere nzvimbo yemifananidzo yesensa uye inodzivirira matambudziko akadai sekukanganiswa kwemifananidzo pamipendero. Pamusoro pezvo, zvakakosha kuona kuti lenzi yemutsara yakasarudzwa inoenderana nerudzi rwekamera kana sisitimu yekuongorora.
Mhando dzema "mount" dzinozivikanwa dzinosanganisira C, CS, F, uye M42; kusawirirana kwe "interface" kuchaita kuti kusangana kana kutarisisa zvisakwanisike. Uyezve, munzvimbo dzekuisa dzine nzvimbo shoma, munhu anofanirawo kufunga nezvemhedzisiro yehukuru hwe "lens" nehuremu pakuisa.
3.Zviratidzo zvekushanda
(1)Mashandiro eMTF: MTF (modulation transfer function) inoyera kugona kwelenzi kugadzirisa pane ma space frequency akasiyana, kusanganisira ruzivo rwakawanda rwakadai sekusiyana, resolution, spatial frequency, uye chromatic aberration. Ichi chiratidzo chakakosha zvikuru mukuyedza kwemaindasitiri uko kuyerwa kwakanyatsojeka kunodiwa. High MTF inovimbisa kuvimbika kweruzivo panguva yekuskena mutsara; nekudaro, kusarudza lenzi ine MTF performance yepamusoro kunopa mhedzisiro yemifananidzo yakawedzerwa.

(2)Kukanganiswa uye chromatic aberration: Kukanganiswa uye kushanduka kwechromatic matambudziko anowanzoitika mumasisitimu e optical. Pakusarudza alenzi, unofanira kutarisisa mwero wekudzora kukanganiswa uye kushanduka kwechromatic. Masisitimu ekuongorora mitsara anonyanya kukanganiswa nekuchinja kwejometri, izvo zvinogona kukonzera zvikanganiso zvekuyera, uye kushanduka kwechromatic kunogona kukanganisa kuenderana kwemifananidzo muma wavelength akasiyana. Kunyanya mumamiriro ezvinhu ekuongorora anoda kunyatsojeka kwakanyanya, zvakakosha kusarudza ma lenzi ane kukanganiswa kwakaderera uye kugadzirisa kukanganiswa kwechromatic kunobudirira; ma lenzi e high-end line-scan anowanzo chengetedza chiyero chekukanganiswa chiri pasi pe0.05%.
(3) Kufanana kwenzvimbo yemufananidzo: Magirazi ekutarisa mutsara anodiwa kuti arambe akasimba munzvimbo yese yemufananidzo, zvichiita kuti mufananidzo uve wakapinza munzvimbo dzakasiyana dzemufananidzo, nekupinza kwakasimba kweinopfuura 98% pakati pepakati nepamipendero.
4.Hunhu hwemufananidzo uye zvinodiwa zvakakosha
(1)Kufananidza kweSpectral: Kana nzvimbo yekuona chiedza ichionekwa, infrared kana ultraviolet, lenzi ine spectral range inoenderana inofanira kusarudzwa kudzivirira kukanganiswa kwespectral uye kuderera kwemufananidzo. Semuenzaniso, kana uchishandisa kamera yeUV kana IR, lenzi yeUV kana IR yakagadzirirwa kugadzirisa chromatic aberration yebhendi iyoyo inofanira kusarudzwa.
(2)Mutengo wemutsetse: Mwero wemutsetse unoenderana nekumhanya kwemutsetse wekugadzirwa, upamhi hwenzvimbo yekuona, uye saizi yepikiseli. Lenzi inofanira kuchengetedza mashandiro ekuona akakwana (MTF, light flux) pamwero wemutsetse unodiwa.
Hunhu hwemifananidzo uye zvinodiwa zvakakosha zvema lenzi ekuongorora mutsara
5.Nzvimbo yekushandisa uye zvinodiwa pakushandisa
Pakusarudza lenzi, zvakakoshawo kusarudza lenzi inoskena mutsara inopa kugara kwenguva refu uye inochinjika zvakasimba—zvichienderana nemamiriro chaiwo ekushandiswa uye zvinodiwa pakushandisa—kuti ive nechokwadi chekuti inoshanda zvakanaka uye kuti mhedzisiro inodiwa iwanikwe munzvimbo dzakasiyana-siyana. Semuenzaniso, munzvimbo dzakaoma dzemaindasitiri (kuzununguka, kusiyana kukuru kwekupisa), malenzi emhando yepamusoro emaindasitiri ane simbi dzakasimba uye magadzirirwo anodzivirira guruva nemarara anofanirwa kufungwa nezvawo.
Muchidimbu, kusarudzwa kwelenzi yekuskena mutsaraIzvi zvinosanganisira maitiro anosanganisira kusimbisa zvinodiwa zvekuongorora, kuverenga ma parameter e optical, kufananidza ma interfaces nema mounting mechanisms, uye kuongorora kuchinjika kwezvakatipoteredza. Maitiro aya anosanganisira kunyanya kufunga nezvezvinhu zvakakosha zvataurwa pamusoro apa kuti uve nechokwadi chekusarudzwa kwe lens yakakodzera, nokudaro kuwana mhedzisiro yemifananidzo yepamusoro uye kusangana nezvinodiwa zvekushandiswa chaiko.
Pfungwa Dzekupedzisira:
Kana muchida kutenga marudzi akasiyana-siyana emalenzi ekutarisa, ekuongorora, emadrone, epamba rakangwara, kana chero chimwe chinhu, tine zvamunoda. Taura nesu nhasi kuti udzidze zvakawanda nezvemalenzi edu nezvimwe zvinhu.
