Ilensi Yengilazi Ye-Chalcogenide YaseShayina Yokwenziwa Kwezicelo Ze-Infrared kanye Nefektri

Ilensi Yengilazi yeChalcogenide Yezinhlelo Zokusebenza Ze-Infrared Isithombe Esivelele

Ilensi Yengilazi yeChalcogenide Yezicelo Ze-Infrared

I-Wavelength infrared inikeza ilensi yengilazi ye-chalcogenide ngobukhulu obudumile kusukela ku-10m m kuya ku-200 mm ububanzi. Usayizi welensi ongaphezu kuka-200mm unganikezwa futhi uma ucela. Isembozo sethu esijwayelekile se-AR ne-DLC silungele kakhulu ibhendi engu-3-5 noma engu-8-12 micron. Ubude obuqondile bamalensi ethu buzolawulwa bufike ku-+/-1% ukubekezelelana, ukuthamba komphezulu okungu-λ/4 @ 632.8nm kanye nokungajwayelekile komphezulu okungaphansi kuka-0.5 micron.

Ulwazi lomkhiqizo:

Ilensi yengilazi yeChalcogenide ilensi yokukhanya eyenziwe ngengilazi yechalcogenide. Ingilazi yeChalcogenide ayiyona into eyodwa kodwa uchungechunge lwezinto ezingabonakali njengengilazi ezidluliselwa ngebhendi ye-infrared. Zine-transmission enhle (>60%) ebangeni eliphakathi kwama-micron angu-2-12, i-index ephansi yokugqama (2.4-2.8@11micron), ushintsho oluphansi lokushisa kwi-index yokugqama kanye nokusabalala okuphansi. Zinezakhiwo ezifanayo zemishini nezokukhanya njenge-germanium, ezenza zifaneleke kahle ukusetshenziswa kwe-IR, ikakhulukazi ekulungisweni kombala ngelensi ye-germanium ohlelweni lokukhanya.

Ngokungafani ne-germanium, edinga ukumbiwa futhi enokunikezwa okulinganiselwe, ingilazi ye-chalcogenide yenziwe ngezinto zokwenziwa futhi amanani ayo azinzile. Ingilazi ye-Chalcogenide inezinga eliphansi lokuncibilika (200-400℃) uma kuqhathaniswa nezinye izinto ze-infrared, ingabunjwa ibe ilensi ye-aspheric ngezindleko eziphansi zokukhiqiza ngobuningi obukhulu.Ilensi Yengilazi Ye-Chalcogenide Ebunjiwe Ye-IR"). Ngenxa yalezi zizathu ezimbili, ilensi yengilazi ye-chalcogenide izodlala indima ebaluleke kakhulu ekusetshenzisweni kwe-infrared.

I-Wavelength Infrared ingakha uhlobo oluhlukahlukene lwelensi yengilazi ye-chalcogenide enezindawo ezibanzi, ezigobile, ezijiyile, ezithambile nezikhipha ukukhanya. Ingilazi ye-Chalcogenide ithandwa kakhulu ezinhlelweni ezisebenza esifundeni se-spectral esingu-3-5 noma esingu-8-12µm, ezinezimbozo ezivimbela ukukhanya (i-AR coating), ukudluliswa okujwayelekile kungakhushulwa kufike ku-97.5-98.5% kuye ngokuthi ububanzi bembozo bungakanani. Singafaka futhi imbozo ye-carbon efana nedayimane (i-DLC coating) noma imbozo eqinile (i-HD coating) ebusweni belensi ukuze sinikeze isivikelo esengeziwe ekuklwebhekeni nasekushayweni.

I-Wavelength infrared ikhiqiza ilensi yengilazi ye-chalcogenide eyindilinga neye-aspheric eyenziwe ngokwezifiso. Ingagxila noma ihlukanise ukukhanya okungenayo ukuze ihlangabezane nezidingo ezithile zesistimu ye-infrared. Uhlelo lokusebenza lungaba yi-thermal imaging, i-thermograph, i-beam collimating, i-spectrum analysis njll.
