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, ngenxa yoko imibala ibonakala isopha, oku kubizwa ngokuba yi-chromatic aberration.Kuba isalathiso apho ukujikwa kwe-spherical kwenzeke kwilensi yeconvex ichasene nelens econcave, ngokudityaniswa kweelensi ezimbini okanye ngaphezulu imitha yokukhanya inokwenziwa ihlangane 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 ezinesalathisi esiphezulu selitye lelitye lenyengane.Ezi zintathu 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-1 conjugation, iqhuba kakuhle kwi-conjugate ratios ukuya kwi-5. Ezi lens zenza i-optics efanelekileyo ye-relay kwi-application ye-on-and off-axis kwaye zihlala zisetyenziswa njengee-eyepieces.

I-Paralight Optics ibonelela nge-Steinheil achromatic triplets ene-MgF2 umaleko omnye ochasene ne-reflective coatings kuluhlu lwamaza angama-400-700 nm kuzo zombini iindawo ezingaphandle, nceda ujonge le grafu ilandelayo kwiireferensi zakho.Uyilo lwethu lwelensi lulungiselelwe ikhompyuter ukuqinisekisa ukuba ukuphambuka kwechromatic kunye nespherical kuncitshiswe ngaxeshanye.Iilensi zikulungele ukusetyenziswa kwezona nkqubo ziphezulu zokucinga kwaye nasiphi na isicelo apho ukuphambuka okungqukuva kunye nekhromatic kufuneka kuncitshiswe.
