ʻOi aku ka maikaʻi o nā Lens Spherical Form
No ka mea, ua hoʻopaneʻe ʻia nā lens no ka liʻiliʻi liʻiliʻi, hiki iā lākou ke hōʻea i ka hana palena ʻokoʻa no nā anawaena kukuna liʻiliʻi.No ka hana maikaʻi loa i ka nānā ʻana i nā noi, e kau i ka ʻili me ka radius pōkole o ka curvature (ʻo ia hoʻi, ʻoi aku ka ʻoi o ka ʻili o ka ʻili) i ke kumu collimated.
Hāʻawi ʻo Paralight Optics i ka N-BK7 (CDGM H-K9L) ʻO nā lens Spherical Form Best i hoʻolālā ʻia e hōʻemi i ka aberration spherical me ka hoʻohana ʻana i nā ʻaoʻao spherical e hana i ka lens.Hoʻohana maʻamau ia i nā conjugates palena ʻole i nā noi mana kiʻekiʻe kahi i koho ʻole ʻia nā pālua.Loaʻa nā lens i ka uhi ʻole ʻia a i ʻole kā mākou pale antireflection (AR) i waiho ʻia ma nā ʻaoʻao ʻelua e hōʻemi i ke kukui i ʻike ʻia mai kēlā me kēia ʻili o ka lens e hōʻemi i ka nui o ka mālamalama e ʻike ʻia mai kēlā me kēia ʻili o ka lens.Hoʻopili ʻia kēia mau uhi AR no ka laulā spectral o 350 – 700 nm (VIS), 650 – 1050 nm (NIR), 1050 – 1700 nm (IR).Hoʻemi nui kēia uhi ʻana i ka noʻonoʻo ʻana o ka ʻili kiʻekiʻe o ka substrate ma lalo o 0.5% no kēlā me kēia ʻili, e hāʻawi ana i ka hoʻoili awelika kiʻekiʻe ma waena o ka pae uhi uhi AR āpau.E nānā i nā kiʻi ma lalo no kāu mau kuhikuhi.
