Aspherical lenses

Pfungwa ndavhiyiwa kuvandudzwa zhinji uye kuchinja kwemakore, kubatsira kugadzirisa matambudziko zvaakaratidzwa. Nhasi pane zvakasiyana-siyana sarudzo pfungwa pamwe lenses zvakasiyana. The kupfuura mukurumbira - aspherical lenses.

Early kuedza kuumba izvo izvi mhando zvakaitwa René Descartes ari 1620s uye Constantine Huygens muna 1630. Sectional chimiro, Descartes akagadzirirwa chinangwa ichi rinozivikanwa Cartesian chikamu.

Smethwick Francis akasika vokutanga yepamusoro aspherical izvo okunze, uye akapa navo Royal Society 27 February, cha1667. Raiva teresikopu, kusanganisira zvitatu aspherical lenses.

Development yokutanga aspherical izvo kuti magirazi rwunoverengerwa pamwe Moritz of Roru. Misa kugadzirwa uye kushandiswa lenses dzakadaro kwakatanga 50s wekupedzisira kuonga remakore nokusunungurwa mavhidhiyo makamera vane aspheric lenses vava dzakakurumbira chaizvo nokuda kwazvo unhu kurekodha.

Kwakajairika lenses vane curved girazi pemvura. Aspherical lenses, Ukuwo, zviri kuitwa chaiwo kukandira girazi, uye kunyange zvazvo vachiri vane curved pamusoro, hazvisi zvachose idenderedzwa.

musiyano uyu chimiro inoita zvakawanda yakarurama vashoma ziso aberrations pane idenderedzwa lenses. Aspherical lenses, kunyanya kushandiswa magirazi, asi vari muhurukuro okupedzisira 30 makore kubudisa yepamusoro mapikicha uye sezvo mutemo makamera diki uye camcorders.

Nokuda kukura maduku uye wakawondereiko kudai mazuva ose vaburitsi pakati zviri nyore zvikuru kugadzirisa pezvakaita izvo kusika, izvo zvinoita kuti tikwanise kuchinja Manyiminya simba mumwe izvo uye yakajeka.

Aspheric lenses vari kudhura uye duku pane kwakajairika lenses, uye unhu kazhinji kupfuura avo vakaitwa nenzira idenderedzwa chimiro.

Pakati kwakadai izvo ane aspherical izvo secrete pamberi kana musana pamusoro (pamusoro Wechipiri idenderedzwa), uye kaviri aspheres apo "sandarara", uye ndiyo kwokunze uye zvemukati pamusoro.

Aspherical lenses nokuti magirazi achienzaniswa idenderedzwa nhaka wandei zvakanakira:

- zvakajeka uye vakwanise munda maonero nemhaka nhete izvo munyonga kuti unobvumira varidzi kuona zvakajeka uye zvakajeka, achitarisa kubva chipi chikamu izvo.

- usingashandi kukanganisa pamwe arikunze (aberration);

- mumwe zvoga manzwisisire zvinhu uye kukura nzvimbo (izvo "oma" hazvideredzi, "pamwe" hakuiti kuwedzera);

- akaderedza uremu Akaroromesawo ukobvu, iro rinopa chiono kururamiswa pasina yainetsa zvakare gobvu idenderedzwa lenses;

- akaderedza ukobvu: mune zvakanaka izvo wakawondereiko kudai mazuva ose nepakati uye wakawondereiko kudai mazuva ose panguva kumucheto Sub-razero;

- hapana kukura kusarurama ziso (anowanzonzi chinoitika apo vakatarisa munhu kubva magirazi).

With kukurumidza kukura zvigadzirwa, aspheric kuonana lenses akava kwakapararira mumakore mashoma apfuura. Vanogona kuitwa yakaoma kana anonzwisisa zvinhu, anogona kushandura ruvara uye chitarisiko womunhu ziso kugadzirisa-siyana zvaakaratidzwa zvirwere. Mumwe zvinetso zvakadaro astigmatism, uko kazhinji kugadziriswa nokushandisa aspherical lenses.

Ndivo duku uye wakawondereiko kudai mazuva ose pane dzose lenses, uye ichi pamwe rinotsanangura sei dzinonzi "shoma" uye nei vane mutengo kwirirei.

Aspheric lenses vari wakawondereiko kudai mazuva ose, uye izvi zvinoreva kuti vari dzakashandisa nani yokusiyana ziso nomumwe muridzi munyonga uye achaita kuvhiringidza zvishoma pamwe rinovaima.

Zvazvakashatira ichi mhando lenses ndiko dzavo kudhura chokuita kugadzira muitiro zvikuru kuoma. Uyezve, ukobvu maduku aspherical lenses kunoreva kuti dziri pedyo kumeso, izvo dzimwe nguva kunokonzera chinooneka reflectance kubva kumativi ose, izvo chete inogona kubviswa nokushandisa Anti-tichifungisisa unhani.
