Hastings Cemented
ʻAchromatic Triplets

He koho maikaʻi nā lens Achromatic no ke koi ʻana i ka mana aberration kiʻekiʻe, no ka mea, hāʻawi lākou i ka hana ʻoi aku ka maikaʻi ma mua o nā singlets spherical.Ua lawa nā pālua achromatic sima no ka nui o nā noi ma nā conjugates palena ʻole, a ʻo nā hui pālua i hoʻopaʻa ʻia he kūpono no nā conjugates palena.Eia nō naʻe, hāʻawi nā triplets Achromatic i ka hana ʻoi aku ka maikaʻi ma mua o nā pālua achromatic, ʻoiai ʻo ka triplet achromatic ka lens maʻalahi loa e hoʻoponopono i nā aberrations chromatic mua a hāʻawi i ka hana maikaʻi ma-axis a me off-axis.

ʻO ka triplets achromatic kahi mea kikowaena lei-index haʻahaʻa i hoʻopaʻa ʻia ma waena o ʻelua mau mea like ʻole kiʻekiʻe-index flint waho.Hiki i kēia mau triplets ke hoʻoponopono i ka axial a me ka lateral chromatic aberration, a ʻo kā lākou hoʻolālā symmetric e hāʻawi i ka hana i hoʻonui ʻia e pili ana i nā pālua cemented.

Hoʻolālā ʻia nā triplets achromatic Hastings e hāʻawi i kahi ratio conjugate palena ʻole a pono no ka nānā ʻana i nā kaola i hui pū ʻia a no ka hoʻonui.Ma ka Contrast, ua hoʻolālā ʻia nā triplets achromatic Steinheil e hāʻawi i kahi ratio conjugate palena a me 1: 1 kiʻi.Hāʻawi ʻo Paralight Optics iā Steinheil a me Hastings achromatic triplets me kahi uhi antireflection no ka laulā hawewe 400-700 nm, e ʻoluʻolu e nānā i ka pakuhi aʻe no kāu mau kuhikuhi.
