Lens ya Silicon (lens ya Si) yo gukoresha infrared

Lens ya silicon ni lens y'urumuri ikozwe muri silicon. Silicon (Si) ni ibikoresho bya kristu bikunze gukoreshwa muri sisitemu za infrared optical zikora mu gice cya spectral ya 3 kugeza kuri 5µm. Ifite refractive index hafi ya 3.4 mu bwoko bwose. Ifite ubucucike buri hasi ugereranyije hagati y'ibikoresho bisanzwe bya infrared, ari na kimwe cya kabiri cy'ibya Ge, GaAs na ZnSe. Bityo ibikoresho bya silicon ni amahitamo meza kuri sisitemu ifite ibibazo by'uburemere. Silicon nayo irakomeye kandi ihendutse kurusha ibikoresho byinshi bisanzwe bya infrared, igabanya ikiguzi cy'ibikoresho mugihe yongera ikiguzi cyo gukora icyarimwe.

Silikoli ikwiriye gukoreshwa muri MWIR ariko kubera ko ifata cyane hejuru ya mikoroni 6, ntabwo ikwiriye gukoreshwa muri LWIR. Ishobora kandi gukoreshwa nk'indorerwamo yo gukoresha muri laser bitewe n'ubushobozi bwayo bwo gutwara ubushyuhe, uburemere bwayo bworoheje, n'ubukomere bwayo.

Uburebure bw'amabara ya infraredishobora gukora ubwoko butandukanye bwa lenzi ya silikoni ifiteubuso buri hejuru, butose, bunini, budafite imiterere n'ubufite aho bunyura.Silikoni ikunzwe cyane mu buryo bukora mu gace ka spectral ka 3-5µm, hamwe n’udupira turwanya urumuri (AR coating), impuzandengo yo kohereza ishobora kugera kuri 98%. Dushobora kandi gushyiramo diyama nka karuboni (DLC coating) cyangwa uburebure bwo hejuru (HD coating) ku buso bw’ikirahuri kugira ngo dukomeze kurinda gushwanyagurika no gukomeretsa.

Infrarouge y'uburebure bw'umurabaikora lensi nziza ya silikoni ikoze mu buryo bw'umuzenguruko n'ubushyuhe. Ishobora kwibanda cyangwa gutandukanya urumuri rwinjira kugira ngo ihuze n'ibisabwa byihariye bya sisitemu ya infrared.
