Hastings Cemented
Achromatic Triplets
Otu atọ achromatic nwere ihe etiti etiti okpueze dị ala nke etinyere n'etiti ihe abụọ dị elu na-adị elu. Atọ atọ ndị a nwere ike idozi ma axial na mpụta chromatic aberration, na nhazi ha na-enye nkwalite arụmọrụ n'ihe metụtara cemented doublets.
Emebere hastings achromatic triplets iji nye oke conjugate na-enweghị ngwụcha ma bara uru maka ilekwasị anya n'ibe agbakọkọtara yana maka ibuli elu. N'ụzọ dị iche, Steinheil achromatic triplet ka emebere iji nye oke conjugate nwere ngwụcha yana onyonyo 1:1. Paralight Optics na-enye ma Steinheil na Hastings achromatic triplets nwere mkpuchi antireflection maka ogologo ogologo ogologo 400-700 nm, biko lelee eserese na-esonụ maka ntụnyere gị.
