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.
