Hastings Cemented
Achromatic Triplets

Iilensi ze-Achromatic lukhetho olulungileyo lokufuna ulawulo olunxaxhileyo oluphezulu, njengoko zibonelela ngokusebenza okungcono kakhulu kuneesingles ezingqukuva.I-achromatic doubles enesamente yanele kwizicelo ezininzi kwii-conjugates ezingapheliyo, kwaye izibini eziphindwe kabini ezenziwe ngesamente zifanelekile kwii-conjugates ezinomda.Nangona kunjalo, ii-triplets ze-Achromatic zibonelela ngokusebenza ngcono ngakumbi kune-achromatic doublets, njengenyani i-achromatic triplet yeyona lens ilula elungisa zonke ii-aberration eziphambili zechromatic kwaye inikeze ukusebenza kakuhle kwi-axis kunye ne-off-axis.

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.

IiHastings achromatic triplets ziyilelwe ukubonelela ngomlinganiselo ongapheliyo weconjugate kwaye ziluncedo ekugxininiseni imiqadi edityanisiweyo kunye nokukhulisa.Ngokuchaseneyo, ii-triplets ze-Steinheil achromatic ziyilelwe ukubonelela ngomlinganiselo ogqityiweyo we-conjugate kunye nomfanekiso we-1:1.IParalight Optics inikezela nge-Steinheil kunye ne-Hastings i-achromatic triplets ene-antireflection coating ye-400-700 nm ububanzi be-wavelength, nceda ujonge igrafu elandelayo kwiireferensi zakho.
