Hastings Wokhazikika
Achromatic Triplets

Magalasi a Achromatic ndi chisankho chabwino chofuna kuwongolera kopitilira muyeso, chifukwa amapereka magwiridwe antchito abwinoko kuposa ma singlets ozungulira. Mawiri a simenti achromatic ndi okwanira kugwiritsa ntchito zambiri pama conjugates opanda malire, ndipo mawiri awiri a simenti ndi abwino kwa ma conjugate okhala ndi malire. Komabe, mapatatu a Achromatic amapereka magwiridwe antchito abwinoko kuposa ma achromatic doublet, zoona zake zenizeni kuti achromatic triplet ndiye mandala osavuta omwe amawongolera ma chromatic aberrations onse ndikupereka magwiridwe antchito abwino pa axis ndi off-axis.

Masamba atatu a achromatic amakhala ndi gawo lapakati lokhala ndi index yotsika yomangidwa pakati pa zinthu ziwiri zofanana za mwala wapamwamba kwambiri. Ma atatuwa amatha kuwongolera kusinthika kwa axial ndi laterial chromatic aberration, ndipo kapangidwe kawo kofananira kamapereka magwiridwe antchito opitilira muyeso ofananira ndi ma simenti awiri.

Hastings achromatic triplets adapangidwa kuti azipereka chiŵerengero cha conjugate chopanda malire ndipo ndi othandiza poyang'ana matabwa osakanikirana ndi kukulitsa. Mosiyana, ma triplets atatu a Steinheil achromatic adapangidwa kuti azipereka chiŵerengero chochepa cha conjugate ndi kujambula kwa 1: 1. Paralight Optics imapereka ma achromatic triplets onse a Steinheil ndi Hastings okhala ndi zokutira zotchingira za 400-700 nm wavelength range, chonde onani graph ili pansipa kuti muwone.
