N-BK7 (CDGM H-K9L)
Nā Lens Bi-Convex

He spherical nā ʻaoʻao ʻelua o Bi-Convex a i ʻole Double-Convex (DCX) Spherical Lenses a loaʻa ka radius like o ka curvature, kaulana lākou no nā noi kiʻi palena ʻole. He kūpono loa nā lens bi-convex ma kahi o ka mea a me ke kiʻi ma nā ʻaoʻao kūʻē o ka lens a ʻo ka ratio o ka mea a me nā kiʻi mamao (conjugate ratio) aia ma waena o 5:1 a me 1:5 no ka hōʻemi ʻana i nā aberrations. Ma waho aʻe o kēia laulā, makemake ʻia nā lens plano-convex.

ʻO N-BK7 ka lei aliʻi borosilicate aniani aniani i hoʻohana nui ʻia i ka ʻike a me ka spectrum NIR, koho maʻamau i kēlā me kēia manawa ʻaʻole pono nā pono hou o UV fused silica (ʻo ia hoʻi, ka hoʻouna maikaʻi ʻana i ka UV a me ka coefficient haʻahaʻa o ka hoʻonui wela) ʻaʻole pono. Hoʻohana paʻa mākou i ka mea like Kina o CDGM H-K9L e pani iā ​​​​N-BK7.
