Muraayadaha Muraayadda Chalcogenide ee loogu talagalay Codsiyada Infrared

Muraayadda galaaska ee Chalcogenide waa muraayad indhaha laga sameeyo oo laga sameeyay galaaska chalcogenide. Muraayadda Chalcogenide ma aha mid ka mid ah laakiin waa taxane galaas ah oo u eg walxo aan qaab lahayn oo lagu gudbiyo xarigga infrared-ka. Waxay lahaayeen gudbin wanaagsan (>60%) oo u dhaxaysa 2-12 micron, tusmada refraction-ka oo hooseysa (2.4-2.8@11micron), isbeddel heerkul oo hooseeya oo ku yimaada tusmada refractive-ka iyo kala firdhinta oo hooseysa. Waxay leeyihiin sifooyin farsamo iyo muuqaal oo la mid ah germanium, taas oo ka dhigaysa inay si fiican ugu habboon yihiin codsiga IR, gaar ahaan sixitaanka midabka iyadoo la adeegsanayo muraayadda germanium ee nidaamka indhaha.

Si ka duwan germanium, oo u baahan in la qodo oo leh sahay xaddidan, galaaska chalcogenide waa macdan macdan ah qiimahooduna waa mid aad u deggan. Galaaska Chalcogenide wuxuu leeyahay dhibic dhalaal yar (200-400℃) marka loo eego walxaha kale ee infrared-ka, waxaa loo qaabeyn karaa muraayad aspheric ah iyadoo kharash yar lagu bixinayo wax soo saar badan (”)Muraayadaha Muraayadda Chalcogenide ee IR-Lagu Qaabeeyey"). Labadan sababood awgood, muraayadda galaaska ee chalcogenide waxay door muhiim ah ka ciyaari doontaa codsiyada infrared-ka.

Mawjadaha Infrared-ka ee Wavelength waxay soo saari karaan qaabab kala duwan oo muraayad galaas ah oo leh dusha sare, gees, gees, gees iyo gees. Muraayadda Chalcogenide ayaa ugu caansan nidaamyada ka shaqeeya gobolka spectral-ka 3-5 ama 8-12µm, iyadoo leh dahaadh ka-hortagga milicsiga (dahaarka AR), celceliska gudbinta waxaa la gaarsiin karaa ilaa 97.5-98.5% iyadoo ku xiran baaxadda dahaarka. Waxaan sidoo kale ku dhejin karnaa dahaarka kaarboonka u eg dheeman (dahaarka DLC) ama dahaarka waara ee sare (dahaarka HD) dusha sare ee muraayadda si loo bixiyo ilaalin dheeraad ah oo ka dhan ah xoqidda iyo saameynta.

Muraayadda Wavelength infrared waxay soo saartaa muraayadda galaaska chalcogenide ee wareegsan iyo kuwa aspheric ah oo tayo leh. Waxay diiradda saari karaan ama kala duwi karaan iftiinka soo socda si ay u daboolaan shuruudaha gaarka ah ee nidaamka infrared. Adeegsigu wuxuu noqon karaa sawir-qaadista kulaylka, thermograph, isku-darka iftiinka, falanqaynta muuqaalka iyo iwm.
