ʻO ke aniani aniani Chalcogenide no nā noi infrared
ʻIke huahana:
ʻO ke aniani Chalcogenide he aniani optical i hana ʻia me ke aniani chalcogenide. ʻAʻole hoʻokahi ke aniani Chalcogenide akā he moʻo o nā mea amorphous e like me ke aniani i hoʻouna ʻia ma ke kāʻei infrared. Loaʻa iā lākou ka 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 germanium, kahi e kūpono ai lākou no ka noi IR, ʻoi aku hoʻi i ka hoʻoponopono kala me ka aniani germanium i ka ʻōnaehana optical.
ʻAʻole e like me ka germanium, kahi e pono ai ke eli ʻia a he palena palena ko ka lako, he synthetic ke aniani chalcogenide a ʻoi aku ka paʻa o kā lākou kumukūʻai. He haʻahaʻa ka heheʻe ʻana o ke aniani Chalcogenide (200-400 ℃) i hoʻohālikelike ʻia me nā mea infrared ʻē aʻe, hiki ke hoʻoheheʻe ʻia i loko o ka lens aspheric me ke kumukūʻai haʻahaʻa no ka hana nui ʻana ("ʻO ke aniani Chalcogenide i hoʻoheheʻe ʻia me ka IR"). No kēia mau kumu ʻelua, e pāʻani ka lens aniani chalcogenide i kahi hana koʻikoʻi i nā noi infrared.
Hiki i ka Wavelength Infrared ke hana i nā ʻano like ʻole o ka aniani chalcogenide me nā ʻili plane, concave, convex, aspheric a me diffractive. ʻO ke aniani Chalcogenide ka mea kaulana loa no nā ʻōnaehana e hana ana ma ka ʻāpana spectral 3-5 a i ʻole 8-12µm, me nā uhi anti-reflective (AR coating), hiki ke hoʻonui ʻia ka hoʻoili awelika i 97.5-98.5% ma muli o ka bandwidth o ka uhi. Hiki iā mākou ke hoʻopili i ka uhi kalapona daimana-like (DLC coating) a i ʻole ka uhi paʻa kiʻekiʻe (HD coating) ma ka ʻili o ka lens e hāʻawi i ka pale hou aku mai ka ʻōpala a me ka hopena.
Hana ka infrared nalu i nā aniani aniani chalcogenide spherical a me aspheric maʻamau. Hiki iā lākou ke kālele a hoʻokaʻawale paha i ke kukuna kukui e hiki mai ana e hoʻokō i nā koi kikoʻī o ka ʻōnaehana infrared. Hiki i ka hoʻohana ʻana ke kiʻi thermal, thermograph, beam collimating, spectrum analysis a me nā mea ʻē aʻe.
Nā kikoʻī:
| Mea Hana | Ke aniani Chalcogenide |
| Anawaena | 10mm-300mm |
| ʻAno | Pōʻai a i ʻole Aspheric |
| Ka lōʻihi o ke kikowaena | <+/-1% |
| Hoʻokaʻawale ʻana | <1 minuke |
| Kiʻi ʻili | <λ/4 @ 632.8nm (ʻIli poepoe) |
| ʻAno ʻole o ka ʻili | < 0.5 micron (ʻIli Aspheric) |
| 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.

Ua kālele ʻia ka nalu i ka hāʻawi ʻana i nā huahana optical kiʻekiʻe no 20 mau makahiki
