Mea aniani Chalcogenide aniani infrared i hoʻoheheʻe ʻia
ʻIke huahana:
Ua wili ʻia, hoʻowali ʻia a hoʻohuli ʻia paha nā aniani infrared kuʻuna e hana i kona ʻili, ʻo ia hoʻi: ma o ka "hana anu". ʻOiai hiki ke hana ʻia nā aniani infrared ma o ka "hana wela", eia mākou i nā aniani infrared i hoʻoheheʻe ʻia i hana ʻia me ka mea aniani chalcogenide. He kūpono loa ke hoʻoheheʻe ʻana o nā aniani no ka hana nui ʻana no ka mea hiki ke hoʻomalu ʻia ke kumukūʻai hana no kēlā me kēia aniani i kahi pae haʻahaʻa loa. Loaʻa i nā aniani i hoʻoheheʻe ʻia ke kūlike maikaʻi o ka huahana i ka hana nui ʻana, kahi e hōʻoiaʻiʻo ai i ka hilinaʻi maikaʻi o nā ʻōnaehana infrared.
ʻAʻole hoʻokahi ke aniani Chalcogenide akā he moʻo o nā mea amorphous e like me ke aniani i hoʻouna ʻia ma ke kāʻei infrared. Hiki iā mākou ke koho wale i ka mea aniani chalcogendie i ka hoʻoheheʻe ʻana i nā lens infrared ma muli o ko lākou mau kiko heheʻe haʻahaʻa i hoʻohālikelike ʻia me nā mea infrared ʻē aʻe.
Loaʻa i ke aniani Chalcogenide ka wikiwiki hoʻoili maikaʻi (>60%) ma ka pae o 2-12 micron, ka helu kuhikuhi haʻahaʻa o ka refraction (2.4-2.8@11micron), ka loli wela haʻahaʻa i ka helu kuhikuhi refractive a me ka hoʻolaha haʻahaʻa. Loaʻa iā lākou nā waiwai mechanical a me optical like me ka germanium, kahi e kūpono ai lākou no ka noi infrared, ʻoi aku hoʻi i ka hoʻoponopono kala me ka lens germanium i ka ʻōnaehana optical.
ʻAʻole e like me ka germanium e pono e eli ʻia a he palena wale nō ka lako, he synthetic nā mea aniani chalcogenide. ʻOi aku ka paʻa a ʻae ʻia ko lākou kumukūʻai. Hiki i nā aniani i hana ʻia me ke aniani chalcogenide ke lilo i pani maikaʻi o nā aniani germanium e hoʻokani lākou i kahi kuleana koʻikoʻi i nā ʻōnaehana infrared hou i hoʻolālā ʻia.
Hiki i ka Navelength Infrared ke hāʻawi i nā aniani infrared aniani chalcogenide i hoʻoheheʻe ʻia me nā ʻili aspheric a me diffractive. ʻO nā aniani aniani Chalcogenide ka mea kaulana loa no nā ʻōnaehana e hana ana ma ka 3-5 mircron a i ʻole 8-12 micron infrared band, ʻoi aku ka awelika o ka hoʻoili ʻana ma luna o 97.5% me nā uhi anti-reflective (uhi AR). Hiki ke hoʻopili ʻia ka uhi kalapona Diamond-like (uhi DLC) a i ʻole ka uhi paʻa kiʻekiʻe (uhi HD) ma ka aniani infrared aniani chalcogenide e hāʻawi i ka pale hou aku mai ka ʻōpala a me ka hopena.
Nā kikoʻī:
Hāʻawi ka infrared nalu i ka aniani infrared chalcogenide i hoʻoheheʻe ʻia me ke anawaena o 1-25 mm. ʻO kā mākou uhi AR a me DLC maʻamau e kūpono loa no ke kāʻei ma 3-5 a i ʻole 8-12 micron. E hoʻomalu ʻia ka lōʻihi o ke kikowaena o kā mākou mau aniani a hiki i ka +/-1% tolerance, ʻoi aku ka liʻiliʻi o ka ʻili ma mua o 0.5 micron, a emi iho ka lens decentration ma mua o 1 arc-minute.
| Mea Hana | Ke aniani Chalcogenide |
| Anawaena | 1mm-25mm |
| ʻAno | ʻAspheric/Diffractive |
| Ka lōʻihi o ke kikowaena | <+/-1% |
| Hoʻokaʻawale ʻana | <1 minuke ʻākuhi |
| ʻAno ʻole o ka ʻili | < 0.5 micron |
| Aperture Moakaka | >90% |
| Uhi ʻana | AR, DLC a i ʻole HD |
Nā Manaʻo:
Loaʻa nā uhi DLC/AR a i ʻole HD/AR ma ke noi.
2. Loaʻa ka hoʻopilikino ʻana no kēia huahana e kūpono i kāu mau koi loea. E haʻi mai iā mākou i kāu mau kikoʻī e pono ai.
NĀ MAHELE HUAHANA
Ua kālele ʻia ka nalu i ka hāʻawi ʻana i nā huahana optical kiʻekiʻe no 20 mau makahiki
