ʻO nā Leni aniani Chalcogenide no nā noi infrared

ʻO ka lens aniani Chalcogenide he lens optical i hana ʻia me ke aniani chalcogenide.ʻAʻole hoʻokahi ke aniani Chalcogenide akā he pūʻulu aniani e like me nā mea amorphous i hoʻouna ʻia i loko o ka hui infrared.Hōʻike lākou i ka hoʻouna maikaʻi (> 60%) i ka laulā o 2-12 micron, haʻahaʻa haʻahaʻa o ka refraction (2.4-2.8@11micron), haʻahaʻa haʻahaʻa hoʻololi i ka refractive index a me ka haʻahaʻa haʻahaʻa.Loaʻa iā lākou nā ʻano mechanical a me ka optical like me ka germanium, kahi e kūpono ai lākou no ka noi IR, ʻoi aku hoʻi i ka hoʻoponopono kala me nā lens germanium i ka ʻōnaehana optical.

ʻAʻole like me ka germanium, pono e ʻeli ʻia a liʻiliʻi ka lako, ʻo ke aniani chalcogenide he synthetic a ʻoi aku ka paʻa o kā lākou kumukūʻai.ʻO ke aniani Chalcogenide he wahi hoʻoheheʻe haʻahaʻa (200-400 ℃) i hoʻohālikelike ʻia me nā mea infrared ʻē aʻe, hiki ke hoʻoheheʻe ʻia lākou i lens aspheric me ke kumu kūʻai haʻahaʻa no ka hana nui ("Makani aniani Chalcogenide IR-Molded”).No kēia mau kumu ʻelua, ʻoi aku ka nui o ka hana nui o ka aniani chalcogenide i nā noi infrared.

Hiki i ka Wavelongth Infrared ke hana i nā ʻano like ʻole o ka lens aniani chalcogenide me nā papa mokulele, concave, convex, aspheric a me nā ʻano like ʻole.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 lawe ʻia i ka 97.5-98.5% ma muli o ka bandwidth o ka uhi.Hiki iā mākou ke hoʻopili i ka uhi kalapona e like me daimana (DLC coating) a i ʻole ka uhi paʻa kiʻekiʻe (HD coating) ma ka ʻili o ka lens e hāʻawi i ka pale hou aku i ka ʻōpala a me ka hopena.

Hana ʻia ka infrared lōʻihi hawewe i nā aniani aniani spherical maʻamau a aspheric chalcogenide.Hiki iā lākou ke nānā a hoʻokaʻawale paha i ke kukui uila e hoʻokō i nā koi kikoʻī o ka ʻōnaehana infrared.Hiki ke noi i ke kiʻi thermal, thermograph, beam collimating, spectrum analysis a pēlā aku.
