I-Steinheil Cemented
I-Achromatic Triplets

Indawo okugxilwe kuyo lapho imisebe yokukhanya edlula phakathi nendawo yelensi ihlangana ihluka kancane endaweni lapho imisebe yokukhanya edlula emaphethelweni elensi ihlangana khona, lokhu kubizwa ngokuthi i-spherical aberration; lapho imisebe yokukhanya idlula kulensi eyi-convex, indawo okugxilwe kuyo yokukhanya okubomvu okunobude beza obude iqhele kakhulu kunendawo okugxilwe kuyo yokukhanya okuluhlaza okwesibhakabhaka okunobude obufushane begagasi, ngenxa yalokho imibala ibonakala iyopha, lokhu kubizwa ngokuthi i-chromatic aberration. Njengoba isiqondiso lapho ukujika okuyindilinga kwenzeka khona kulensi eyi-convex kuphambene nelensi eqondile, ngokusebenzisa inhlanganisela yamalensi amabili noma ngaphezulu imisebe yokukhanya ingenziwa ukuthi ihlangane ifinyelele endaweni eyodwa, lokhu kubizwa ngokuthi ukulungiswa kokushintshashintsha. Amalensi e-Achromatic alungile kukho kokubili ukuphambuka kwe-chromatic nokuyisiyingi. Ama-chromat ethu ajwayelekile nangokwezifiso aklanywe futhi akhiqizwa ukuze enelise ukubekezelelana okuqinile okudingekayo kumasistimu anamuhla asebenza kahle e-laser, electro-optical kanye ne-imaging.

Ama-triplets e-achromatic ahlanganisa ingxenye yesikhungo somqhele enenkomba ephansi efakwe phakathi kwama-elementi amabili afanayo angaphandle anenkomba ephezulu. Lawa ma-triplets ayakwazi ukulungisa kokubili i-axial ne-lateral chromatic aberration, futhi idizayini yawo ye-symmetric inikeza ukusebenza okuthuthukisiwe okuhlobene nokuphindwe kabili kukasimende. Ama-triplets e-Steinheil aklanyelwe ngokukhethekile ukuhlanganiswa kwe-1: 1, asebenza kahle ngezilinganiso ze-conjugate kufika ku-5. Lawa ma-lens enza ama-optics adluliselwe kahle kukho kokubili ukusetshenziswa kwe-on-axis futhi avame ukusetshenziswa njengezinto zamehlo.

I-Paralight Optics inikeza ama-Steinheil achromatic triplets ane-MgF2 ungqimba olulodwa lwe-anti-reflective coatings yobubanzi be-wavelength obungu-400-700 nm kuzo zombili izindawo ezingaphandle, sicela uhlole igrafu elandelayo ukuze uthole izithenjwa zakho. Idizayini yethu yelensi ilungiselelwe ikhompuyutha ukuze kuqinisekiswe ukuthi ukuphambuka kwe-chromatic kanye nendilinga kuncishiswa kanyekanye. Amalensi afanele ukusetshenziswa kumasistimu wokuthwebula anokulungiswa okuphezulu kakhulu nanoma yiluphi uhlelo lokusebenza lapho ukuphambuka okuyindilinga nokukhromatic kufanele kuncishiswe.
