Magalasi Opangidwa ndi Infrared Lens Chalcogenide Glass Material

Magalasi achikale a infrared amapukutidwa, kupukutidwa kapena diamondi kukhala pamwamba pake, mwanjira ina: kudzera mu "kupanga kozizira".Ngakhale mandala a infrared amathanso kupangidwa kudzera mu "kupanga matenthedwe", apa tapanga magalasi opangidwa ndi galasi la chalcogenide.Kupanga ma lens ndikoyenera kupanga kuchuluka kwakukulu chifukwa mtengo wopangira ma lens ukhoza kuwongoleredwa pamlingo wotsika kwambiri.Magalasi owumbidwa amakhalanso ndi kusasinthika kwazinthu pakupanga zinthu zambiri, zomwe zimatsimikizira kudalirika kwa makina a infrared.
Galasi ya Chalcogenide si imodzi koma magalasi angapo ngati zida za amorphous zomwe zimatumizidwa mu bandi ya infrared.Titha kungosankha zinthu zamagalasi a chalcogendie pamawumbidwe a mandala a infrared chifukwa cha kusungunuka kwawo kochepa poyerekeza ndi zida zina za infuraredi.
Magalasi a Chalcogenide ali ndi mpweya wabwino wotumizira (> 60%) mumtundu wa 2-12 micron, chiwerengero chochepa cha refraction (2.4-2.8@11micron), kutsika kwa kutentha kwa chiwerengero cha refractive ndi kufalikira kochepa.Amakhala ndi mawonekedwe ofanana ndi mawotchi ndi mawonekedwe a germanium, omwe amawapangitsa kukhala oyenera kugwiritsa ntchito infuraredi, makamaka pakuwongolera mitundu ndi mandala a germanium mu mawonekedwe a kuwala.
Mosiyana ndi germanium yomwe imayenera kukumbidwa ndipo imakhala ndi zochepa, zida zamagalasi za chalcogenide ndizopanga.Mitengo yawo imakhala yokhazikika komanso yovomerezeka.Magalasi opangidwa ndi magalasi a chalcogenide amatha kukhala abwino m'malo mwa mandala a germanium omwe angatenge gawo lofunikira kwambiri pamakina atsopano opangidwa ndi infrared.

Wavelength Infrared imatha kupereka magalasi opangidwa ndi chalcogenide opangidwa ndi galasi lokhala ndi aspheric komanso malo owoneka bwino.Magalasi agalasi a Chalcogenide ndiwodziwika kwambiri pamakina omwe amagwira ntchito mu 3-5 mircron kapena 8-12 micron infrared band, kufala kwapakati pa 97.5% yokhala ndi zokutira zotsutsana ndi reflective (AR zokutira).zokutira ngati diamondi ngati kaboni (DLC zokutira) kapena zokutira zolimba kwambiri (zopaka za HD) zithanso kuyikidwa pagalasi yagalasi ya chalcogenide infrared lens kuti ipereke chitetezo chowonjezera pakukanda ndi kukhudzidwa.
