Leni Germanium (Lens Ge) no nā noi Infrared

Hāʻawi ka nalu infrared i ka lens germanium i nā nui kaulana mai 10m m a 200 mm ke anawaena.Hiki ke hāʻawi ʻia ka nui o ka Lens ma luna o 200mm akā no ka noʻonoʻo ʻana i ke kiʻekiʻe kiʻekiʻe o nā mea germanium, kaumaha loa ia no nā ʻōnaehana infrared maʻamau.ʻO kā mākou maʻamau AR a me DLC ka uhi ʻoi aku ka maikaʻi no ka band ma 3-5 a i ʻole 8-12 micron.E mālama ʻia ka lōʻihi kiko o kā mākou mau lens a hiki i +/-1% ka hoʻomanawanui, ka palahalaha o ka ʻili λ/4 @ 632.8nm a me ka ʻole o ka ʻili ma lalo o 0.5 micron.

ʻO ka lens Germanium he lens optical i hana ʻia me ka germanium.ʻO ka Germanium (Ge) kahi mea aniani me ka helu kuhikuhi refractive kiʻekiʻe loa (4.002@11µm) o nā mea i hoʻohana mau ʻia.Loaʻa iā ia ka hoʻopuehu haʻahaʻa haʻahaʻa, paʻakikī kiʻekiʻe a me ka nui.Ma muli o kona ākea ākea (ma luna o 45% i ka 2-12 micron band) a me ka opaque i ka UV a me ke kukui ʻike ʻia, ua kūpono ʻo Germanium no ka noi IR e like me nā ʻōnaehana kiʻi wela, nā noi kahua infrared a me nā mea analytic precision.

Hoʻopili pū ʻia ʻo Germanium i ka mahuka wela.Me ka ulu ʻana o ka mahana, piʻi wikiwiki ka absorption.Ma muli o kēia hopena holo wela, ʻaʻole kūpono ka lens germanium e hoʻohana i nā mahana ma luna o 100°C.

Hiki i ka Wavelongth Infrared ke hana i nā ʻano ʻano like ʻole o ka lens germanium me ka mokulele, concave, convex, aspheric a me nā papa ʻokoʻa.ʻO Germanium ka mea kaulana loa no nā ʻōnaehana e hana ana ma ka 3-5 a i ʻole 8-12µm spectral region, me nā uhi anti-reflective (AR coating), hiki ke lawe ʻia ka awelika 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 ka nalu infrared i ka lens spherical maʻamau a me aspheric germanium lens.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.
