Ungayikhetha njani i-Aberration Rate efanelekileyo yeeLensi zeZimboni?

Ukukhetha izinga elifanelekileyo lokujika kwesantyailensi yemizi-mvelisoifuna ukuqwalaselwa kwezinto ezininzi, ezinje ngeemfuno ezithile zesicelo, iimfuno zokuchaneka komlinganiselo, uhlahlo lwabiwo-mali lweendleko, njl. Nazi ezinye iingcebiso kunye nezinto ekufuneka ziqwalaselwe xa ukhetha:

1.Chonga iimfuno zesicelo

Chonga iimfuno ezithile zezicelo zoshishino zomgangatho womfanekiso kunye nokuchaneka kokulinganisa, kwaye umisele imigangatho yomgangatho womfanekiso efunekayo ngokusekelwe kwiimfuno. Umzekelo, kwezinye izicelo ezifuna ukucaca okuphezulu komfanekiso kunye nokuchaneka, kunokufuneka ukhethe ilensi yezimboni enesantya esiphantsi sokuphambuka.

2.Ukuqondaaukugxekwatii-ypes

Qonda impembelelo yamazinga ahlukeneyo okuphambuka kumgangatho womfanekiso, kubandakanya ukugqwetheka, ukuphambuka kwe-chromatic, ukusasazeka kwamabala, njl.njl., ukuze ukhethe ilensi yemizi-mveliso efanelekileyo kwizicelo ezithile.

Ukuphazamiseka kwahlulwe ngokubanzi kwiingxaki ze-radial kunye neengxaki ze-tangential. Ukuphazamiseka kwe-radial kudla ngokubonakala ngokuphambuka kwezinto kumphetho womfanekiso, ngelixa ukuphazamiseka kwe-tangential kubangelwa ziimpazamo ze-angular phakathi kwelensi kunye neplani yomfanekiso. Kwiinkqubo ezininzi zoshishino, ukuphazamiseka kwe-radial mhlawumbi yeyona ngxaki iphambili.

3.Jonga iinkcukacha zelensi

Niniukukhetha ilensi, kukwacetyiswa ukuba ujonge idatha yesantya sokuphambuka kwiinkcukacha zayo, edla ngokunikezelwa njengepesenti okanye ixabiso le-pixel. Kwizicelo ezifuna ukulinganiswa okuchanekileyo, kungangcono ukhethe ilensi enesantya sokuphambuka esiphantsi.

4.Ukuqonda indlela yokuvavanya

Abavelisi belensi badla ngokubonelela ngedatha okanye iindlela zokuvavanya ukungazinzi. Ukuqonda ezi ndlela zokuvavanya kunokunceda ukuvavanya ngokuchanekileyo ukusebenza kokungazinzi kwelensi.

5.Cinga ngebhajethi yeendleko

Ngokubanzi, iilensi zoshishino ezinezinga eliphantsi lokungazinzi ziya kubiza kakhulu. Ke ngoko, kuyimfuneko ukuqwalasela uhlahlo lwabiwo-mali lweendleko ukuze kuqinisekiswe ukuba ingaba kufuneka ilensi ekumgangatho ophezulu.

6.Cinga ngezinto ezisingqongileyo

Kwakhona kuyimfuneko ukuqwalasela izinto ezifana neemeko zokukhanya kunye notshintsho lobushushu kwindawo yokusebenza ukuqinisekisa uzinzo kunye nokuthembeka kwelensi.

Ukongeza kwizinga lokungazinzi,ukhetho lwelensiKwakhona kufuneka kuqwalaselwe ukuba ezinye iiparameter ezifana nesisombululo, intsimi yombono, ubude befocal, njl. ziyahlangabezana na neemfuno.

Iingcinga Zokugqibela:

Ukuba unomdla wokuthenga iintlobo ngeentlobo zeelensi zokujonga, ukuskena, iidrone, ikhaya elikrelekrele, okanye naluphi na olunye uhlobo lokusetyenziswa, sinazo izinto ozifunayo. Nxibelelana nathi namhlanje ukuze ufunde okungakumbi ngeelensi zethu kunye nezinye izixhobo.
