Magalasi a Chalcogenide a China Opangira ndi Kupangira Mafakitale a Infrared

Lenzi ya Galasi ya Chalcogenide Yogwiritsira Ntchito Infrared Chithunzi Chowonetsedwa

Magalasi a Chalcogenide Ogwiritsidwa Ntchito pa Infrared

Magalasi a infrared a Wavelength amapereka magalasi a chalcogenide okhala ndi kukula kodziwika kuyambira 10m mpaka 200 mm m'mimba mwake. Kukula kwa magalasi opitilira 200mm kungaperekedwenso ngati mungafune. Chophimba chathu chokhazikika cha AR ndi DLC ndi choyenera kwambiri pa bandeji ya 3-5 kapena 8-12 micron. Kutalika kwa ma lens athu kungawongoleredwe mpaka +/-1% kulekerera, kusalala kwa pamwamba λ/4 @ 632.8nm ndi kusakhazikika kwa pamwamba kosakwana 0.5 micron.

Lenzi yagalasi ya Chalcogenide ndi lenzi yowala yopangidwa ndi galasi la chalcogenide. Galasi ya Chalcogenide si imodzi koma ndi zinthu zingapo zagalasi zosaoneka bwino zomwe zimafalikira mu infrared band. Zinali ndi kufalikira kwabwino (>60%) pakati pa 2-12 micron, index yotsika ya refraction (2.4-2.8@11micron), kusintha kochepa kwa kutentha mu index ya refractive komanso kufalikira kochepa. Zili ndi mawonekedwe ofanana ndi a germanium, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito mu IR, makamaka pakukonza mitundu ndi lenzi ya germanium mu optical system.

Mosiyana ndi germanium, yomwe imafunika kukumba ndipo ili ndi zochepa, magalasi a chalcogenide ndi opanga ndipo mitengo yawo ndi yokhazikika. Magalasi a Chalcogenide ali ndi malo otsika osungunuka (200-400℃) poyerekeza ndi zinthu zina za infrared, amatha kupangidwa kukhala magalasi a aspheric okhala ndi mtengo wotsika kuti apange zinthu zambiri (”Galasi la Chalcogenide lopangidwa ndi IR"). Pazifukwa ziwirizi, magalasi agalasi a chalcogenide angathandize kwambiri pakugwiritsa ntchito ma infrared.

Magalasi a infrared a Wavelength amatha kupanga mawonekedwe osiyanasiyana a magalasi a chalcogenide okhala ndi malo ozungulira, opindika, ozungulira, aspheric komanso otulutsa kuwala. Galasi la Chalcogenide ndilodziwika kwambiri pamakina omwe amagwira ntchito m'dera la 3-5 kapena 8-12µm spectral, okhala ndi zophimba zotsutsana ndi kuwala (AR), kufalikira kwapakati kumatha kufika pa 97.5-98.5% kutengera kuchuluka kwa zophimbazo. Tithanso kugwiritsa ntchito zokutira za kaboni ngati diamondi (DLC) kapena zokutira zolimba kwambiri (HD) pamwamba pa lens kuti tipewe kukanda ndi kugwedezeka.

Magalasi a infrared a Wavelength amapanga magalasi apamwamba ozungulira komanso aspheric chalcogenide. Amatha kuyang'ana kapena kusiyanitsa kuwala komwe kukubwera kuti akwaniritse zofunikira za dongosolo la infrared. Kugwiritsa ntchito kungakhale kujambula kutentha, thermograph, beam collimating, kusanthula kwa spectrum ndi zina zotero.
