Izinto zeglasi zeChalcogenide zeLens eziBunjiweyo

Iilensi ze-infrared zemveli ziyagaywa, zipolishwe okanye zijikwe zibe yidayimani ukuze zenze umphezulu wazo, ngamanye amazwi: ngokusebenzisa "ukwenziwa okubandayo". Ngelixa iilensi ze-infrared zinokwenziwa "ngokwenziwa okushushu", apha sineelensi ze-infrared ezibunjiweyo ezenziwe ngezinto zeglasi ze-chalcogenide. Ukubumba ilensi kulungele ngokukodwa imveliso eninzi kuba ixabiso lokwenziwa ngelensi nganye linokulawulwa kwinqanaba eliphantsi kakhulu. Iilensi ezibunjiweyo zikwanokuhambelana okuhle kwemveliso kwimveliso yobuninzi, okuqinisekisa ukuthembeka okuhle kweenkqubo ze-infrared.
Iglasi yeChalcogenide ayilolunye kodwa luluhlu lwezinto ezingafaniyo neglasi ezithunyelwa kwi-infrared band. Singakhetha kuphela izinto zeglasi zeChalcogendie kwi-infrared lens molding ngenxa yokuba zincinci xa zithelekiswa nezinye izinto ze-infrared.
Iglasi yeChalcogenide inesantya esihle sokudluliselwa (>60%) kuluhlu lwe-2-12 micron, i-index ephantsi ye-refraction (2.4-2.8@11micron), utshintsho oluphantsi lobushushu kwi-index ye-refractive kunye ne-dispersion ephantsi. Zineempawu ezifanayo zoomatshini kunye ne-optical njenge-germanium, ezenza zilungele ukusetyenziswa kwe-infrared, ngakumbi ekulungisweni kombala nge-germanium lens kwinkqubo ye-optical.
Ngokungafaniyo negermanium ekufuneka imbiwe kwaye inombane omncinci, izinto zeglasi zechalcogenide zenziwe ngokwenziwa. Amaxabiso azo azinzile kwaye ayamkeleka. Iilensi ezenziwe ngeglasi yechalcogenide zinokuba ziindawo ezilungileyo zokutshintsha ilensi yegermanium eziya kudlala indima ebaluleke ngakumbi kwiinkqubo ezintsha ze-infrared eziyiliweyo.

I-Wavelength Infrared inokubonelela ngelensi ye-infrared yeglasi ye-chalcogenide ebunjiweyo eneendawo ezingabonakaliyo nezisasazekayo. Iilensi zeglasi ye-Chalcogenide zithandwa kakhulu kwiinkqubo ezisebenza kwi-3-5 mircron okanye i-8-12 micron infrared band, udluliselo oluqhelekileyo olungaphezulu kwe-97.5% kunye neengubo ezichasene nokukhanya (i-AR coating). Ingubo ye-carbon efana nedayimani (i-DLC coating) okanye i-high durable coating (i-HD coating) nayo inokusetyenziswa kwilensi ye-infrared yeglasi ye-chalcogenide ukubonelela ngokhuseleko olongezelelweyo ekukrweleni nasekuchaphazelekeni.
