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 kwilensi eyi-convex, indawo okugxilwe kuyo yokukhanya okubomvu okunobude beza obude ikude kakhulu kunendawo okugxilwe kuyo yokukhanya okuluhlaza okwesibhakabhaka okunobude obufushane beza, ngenxa yalokho imibala ibonakala iyopha, lokhu kubizwa ngokuthi i-chromatic aberration.Njengoba indlela lapho ukujika okuyindilinga kwenzeka khona kulensi eyi-convex iphambene 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 e-laser, i-electro-optical kanye ne-imaging yanamuhla.

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 wokucabanga anesinqumo esiphezulu futhi noma yiluphi uhlelo lokusebenza lapho ukuphambuka okuyindilinga nokukhromatic kufanele kuncishiswe.
