Steinheil Cemented
Achromatic Triplets

Indawo ekugxilwe kuyo apho imitha yokukhanya edlula embindini welensi idibana yohluka kancinane kwindawo ekugxilwe kuyo apho imitha yokukhanya edlula kwincam yelensi idibana, oku kubizwa ngokuba yi-spherical aberration; xa imitha yokukhanya idlula kwilensi yeconvex, indawo ekugxilwe kuyo isibane esibomvu esinobude obude bezavevele ikude kunendawo ekugxilwe kuyo yokukhanya okublowu okunobude obufutshane obunobude obufutshane, ngenxa yoko imibala ibonakala isopha, oku kubizwa ngokuba yi-chromatic aberration. Ekubeni isalathiso esingqukuva senzeke kwilensi yeconvex sichasane nelensi econcave, ngokudityaniswa kweelensi ezimbini okanye ngaphezulu imitha yokukhanya inokwenziwa ijike iye kwindawo enye, oku kubizwa ngokuba yi-aberration correction. Iilensi ze-Achromatic zichanekile kuzo zombini ii-aberration zechromatic kunye nespherical. Ii-achromats zethu ezisemgangathweni kunye nesiko ziyilelwe kwaye zenziwe ukuba zanelise ukunyamezela okungqongqo okufunekayo kwiinkqubo zanamhlanje ze-laser ephezulu, i-electro-optical kunye ne-imaging systems.

I-achromatic triplets iqulathe isithsaba esisesiphakathini sesalathiso esisezantsi into edityaniswe phakathi kwezinto ezimbini ezifanayo ezinesalathiso esiphakamileyo samatye angaphandle. Ezi zithathu ziyakwazi ukulungisa zombini i-axial kunye ne-lateral chromatic aberration, kwaye uyilo lwazo lwe-symmetric lubonelela ngokusebenza okuphuculweyo ngokunxulumene nokuphindwe kabini kwesamente. I-triplets ye-Steinheil yenzelwe ngokukodwa i-1: i-conjugation ye-1, iqhuba kakuhle kwi-conjugate ratios ukuya kwi-5. Ezi lens zenza i-optics efanelekileyo ye-relay optics zombini kunye ne-off-axis application kwaye zihlala zisetyenziswa njenge-eyepieces.

IParalight Optics ibonelela nge-Steinheil achromatic triplets ene-MgF2 umaleko omnye ochasene ne-reflective coatings kwi-400-700 nm ububanzi be-wavelength kwiindawo zombini ezingaphandle, nceda ujonge igrafu elandelayo kwiireferensi zakho. Uyilo lwethu lwelensi lulungiselelwe ikhompyuter ukuze kuqinisekiswe ukuba ukuphambuka kwechromatic kunye nespherical kuncitshiswa ngaxeshanye. Iilensi zikulungele ukusetyenziswa kwezona nkqubo ziphezulu zokujonga umfanekiso kunye naso nasiphi na isicelo apho ukuphambuka okungqukuva kunye nekhromatic kufuneka kuncitshiswe.
