Ikirahuri cya Chalcogenide gikoreshwa mu gukoresha infrared

Ikirahuri cya Chalcogenide ni lenzi y'urumuri ikozwe mu kirahuri cya chalcogenide. Ikirahuri cya Chalcogenide si kimwe mu bintu bisa n'ibirahuri bidafite isura, byoherezwa mu mugozi wa infrared. Byari bifite uburyo bwiza bwo kohereza amakuru (>60%) hagati ya mikoroni 2-12, ubunini buke bwo kugarura amakuru (2.4-2.8@11micron), impinduka nke z'ubushyuhe mu bunini bwo kugarura amakuru no gukwirakwira ku buryo buke. Bifite imiterere isa na germanium, ituma bikoreshwa neza mu ikoranabuhanga rya IR, cyane cyane mu gukosora amabara hakoreshejwe lenzi ya germanium muri sisitemu y'ikoranabuhanga.

Bitandukanye na germanium, ikeneye gucukurwa kandi ikaba ifite ubushobozi buke bwo kuyicukura, ikirahure cya chalcogenide ni icya sintetike kandi ibiciro byacyo birahamye. Ikirahure cya Chalcogenide gifite ubushobozi bwo gushonga buke (200-400℃) ugereranije n'ibindi bikoresho bya infrared, gishobora guhindurwamo lens ya aspheric ku giciro gito kugira ngo gikoreshwe mu bwinshi (”Ikirahuri cya Chalcogenide cyabumbwe na IR"). Kubera izi mpamvu ebyiri, lenzi y'ikirahure ya chalcogenide yagira uruhare runini mu bikorwa bya infrared.

Ikirahure cya Wavelength Infrared gishobora gukora imiterere itandukanye ya lens ya chalcogenide ifite ubuso bunini, buto, bunini, butagira imiterere n'ubuso butanga imiterere. Ikirahure cya Chalcogenide gikunzwe cyane ku buryo bukora mu gace ka spectral ka 3-5 cyangwa 8-12µm, gifite ibyuma birwanya imiterere y'urumuri (AR coating), impuzandengo yo kohereza ishobora kugera kuri 97.5-98.5% bitewe n'uburyo uburebure bw'urumuri butanga. Dushobora kandi gushyiramo diyama nka karuboni (DLC coating) cyangwa uburebure burambye (HD coating) ku buso bwa lens kugira ngo dutange uburinzi bwiyongereye ku gushwanyagurika no kugongwa.

Infrarouge ya Wavelength ikora lenzi nziza ya chalcogenide y’ikirahure ikozwe mu buryo bwa spheric na aspheric. Ishobora kwibanda cyangwa gutandukanya urumuri rwinjira kugira ngo ihuze n’ibisabwa byihariye bya sisitemu ya infrarouge. Ikoreshwa rishobora kuba ifoto y’ubushyuhe, thermograph, collimating y’imirasire, isesengura rya spectrum n’ibindi.
