Ke hoʻoholo nei ma waena o kahi lens plano-convex a me kahi lens bi-convex, ʻo ia mau mea ʻelua e hoʻohuli ai i ka mālamalama hanana collimated, ʻoi aku ka maikaʻi o ke koho ʻana i kahi lens plano-convex inā ʻoi aku ka liʻiliʻi o ka hoʻonui piha i ka 0.2 a i ʻole 5. Ma waena o kēia mau waiwai ʻelua, makemake nui ʻia nā lens bi-convex.
Ma muli o kona ākea ākea (2 - 16 µm) a me nā waiwai kemika paʻa, ua kūpono ʻo Germanium no nā noi laser IR, maikaʻi loa ia no ka palekana, ka pūʻali koa a me nā noi kiʻi. Eia naʻe, ʻo nā waiwai hoʻoili o Ge, he ʻano wela loa ia; ʻo ka ʻoiaʻiʻo, lilo ka absorption i mea nui loa i aneane ʻeleʻele ka germanium ma 100 °C a ʻaʻole loa e hoʻouna ʻia ma 200 °C.
Hāʻawi ʻo Paralight Optics i nā Lenses Germanium (Ge) Plano-convex (PCX) i loaʻa me kahi uhi AR broadband no ka 8 µm a i ka 12 μm spectral i waiho ʻia ma nā ʻaoʻao ʻelua. Hoʻemi nui kēia uhi ʻana i ka noʻonoʻo ʻana o ka ʻili kiʻekiʻe o ka substrate, e hāʻawi ana i ka hoʻoili awelika ma mua o 97% ma luna o ka laulā uhi AR āpau. E nānā i nā kiʻi no kāu mau kuhikuhi.

He aha kāu e loaʻa ai me kahi Paralight Optics Germanium Plano-Convex Lens
● Ke hele nei kēlā me kēia lens i kahi kaʻina nānā pono ma mua o ka haʻalele ʻana i kā mākou hale hana.
● Nā anawaena mai ka 25.4-50.8mm a me nā koho hou aʻe ma ke noi.
● Loaʻa ka lōʻihi o ka nānā ʻana (EFL) mai 25.4-200mm.
● Hiki ke loaʻa nā uhi ʻokoʻa hou ma ke noi.
