Ukuchaneka kweAplanatic
Iimbini zeAchromatic

Ilensi ye-achromatic, ekwaziwa ngokuba yi-achromat, ibandakanya izinto ezi-2 zamehlo ezidityanisiweyo kunye, ngokuqhelekileyo isalathiso esisezantsi esilungileyo (esidla ngokuba sisithsaba seglasi ye-biconvex lens) kunye nesalathiso esinegative ephezulu (enjengeglasi yelitye).Ngenxa yomahluko kwizalathisi ezihlaziyiweyo, ukusasazwa kwezinto ezimbini ngokuyinxenye kuhlawulela omnye komnye, ukuphambuka kwechromatic ngokubhekiselele kumaza amabini akhethiweyo kuye kwalungiswa.Zenziwe zalungiswa ukuze zilungele zombini i-on-axis spherical and chromatic aberrations.Ilensi ye-Achromatic iya kubonelela ngobungakanani bendawo encinci kunye nomgangatho womfanekiso ophakamileyo kunelensi eyodwa enokuthelekiseka enobude obugxilileyo obufanayo.Oku kubenza balungele ukwenza umfanekiso kunye ne-broadband egxile kwizicelo.Ii-Achromats ziyilelwe kwaye zenziwe ukwanelisa ukunyamezelana okungqongqo okufunekayo kwi-laser yanamhlanje ephezulu, i-electro-optical kunye ne-imaging systems.

I-Paralight Optics inikezela ngeendlela ezahlukeneyo ze-achromatic optics kunye nobukhulu obuchazwe ngabathengi, ubude obugxininisekileyo, izinto ze-substrate, izinto zesamente, kunye neengubo zenziwe ngokwezifiso.Iilensi zethu ze-achromatic zigquma i-240 - 410 nm, 400 - 700 nm, 650 - 1050 nm, 1050 - 1620 nm, 3 - 5 µm, kunye ne-8 - 12 µm ububanzi bobude bamaza.Zifumaneka zinganyuswanga, zixhonywe okanye zidibene ngambini.Ngokumalunga ne-achromatic doublet kunye ne-triplets line-up, sinokubonelela ngokuphindwe kabini kwe-achromatic (zombini umgangatho kunye nokuchaneka kwe-aplanatic), i-cylindrical achromatic doublets, i-achromatic doublet pairs ezongezelelwe i-conjugates enesiphelo kwaye ilungele ukuhanjiswa komfanekiso kunye neenkqubo zokukhulisa, i-achromatic doublets efakwe emoyeni. ezilungele izicelo eziphezulu zamandla ngenxa yomonakalo omkhulu kunee-achromats ezinesamente, kunye neetriplets ze-achromatic ezivumela ulawulo lokuphambuka okukhulu.

Ii-Aplanats ezichanekileyo zeParalight Optics (i-Aplanatic Achromatic Doublets) azilungiswanga kuphela kwi-spherical aberration kunye nombala we-axial njenge-Standard Cemented Achromatic Doublets kodwa ziphinde zilungiswe kwi-coma.Le ndibaniselwano ibenza babe ne-aplanatic kwindalo kwaye banikeze ukusebenza okungcono kokubona.Zisetyenziswa njengeenjongo zokugxila kwi-laser nakwiinkqubo ze-electro-optical & imaging.
