Ilensi ye-infrared yesithombe sokushisa esibanzi

I-Wavelength Infrared yakhiqiza amashumi ezinkulungwane zamalensi e-infrared e-Thermal Imaging Rifle Scopes minyaka yonke, enikezwa izinkampani ezidumile ze-thermal scope emhlabeni jikelele.

I-thermal scope ingathola imizimba efudumele ezindaweni ezipholile ngokwemvelo ngokuqhathaniswa kwayo kokushisa. Ngokungafani ne-thermal scope yendabuko yokubona ebusuku, ayidingi ukusekelwa kokukhanya kwangemuva ukuze yakhe umbono obonakalayo. I-thermal scope ingasebenza imini nobusuku, inqume intuthu, inkungu, uthuli nezinye izithiyo zemvelo. Okuyenza ibe usizo ngokukhethekile ekuzingeleni, ekusesheni nasekusindiseni, noma emisebenzini yamaqhinga.

Ilensi ye-infrared ingenye yezingxenye eziyinhloko ku-scope yokushisa, ehlanganiswe nenzwa yokushisa ukuguqula isithombe se-infrared sibe yizibonakaliso ze-elekthronikhi. Ngemuva kwalokho izimpawu ziguqulwa zibe isithombe esibonakalayo ukuze siboniswe esikrinini se-OLED samehlo abantu. Ukucaca, ukuhlanekezela, ukukhanya kwesithombe sokugcina; ububanzi bokutholwa, ukuqashelwa kanye nokuhlonza; ukusebenza ezimweni ezahlukene zemvelo, ngisho nokuthembeka kwe-scope kuthinteka ngqo yilensi ye-infrared. Kubaluleke kakhulu ukukhetha ilensi ye-infrared efanelekile ekuqaleni kwanoma yikuphi ukwakheka kwe-scope yokushisa.

Nakuba ilensi ye-infrared efanele ibaluleke kakhulu endaweni enhle yokushisa, kunezinye futhi imiphumela ebalulekile okufanele igxilwe kuyo.

Ubude Bokugxila (FL) kanye ne-F#: Ubude bokugxila belensi ye-infrared bunquma ububanzi be-DRI be-scope yokushisa. Ngamanye amazwi, ungabona ibanga elingakanani. Ubude bokugxila obuvame kakhulu obusetshenziswa ku-scope yokushisa. I-F# isilinganiso sobude bokugxila besistimu nobubanzi be-pupil yokungena, i-F# = FL/D. Uma i-F# yelensi incane, kulapho i-pupil yokungena inkulu khona. Ukukhanya okwengeziwe kuzoqoqwa yilensi ngenkathi izindleko zikhuphuka ngesikhathi esifanayo. Ngokuvamile ilensi ene-F#1.0-1.3 ifaneleka ukusetshenziswa kwe-scope yokushisa.

Uhlobo Lwenzwa: Inzwa ye-infrared ithatha ingxenye enkulu yezindleko eziphelele ze-scope yokushisa. Inquma ukuthi ungabona UBANZI kangakanani nge-scope yokushisa. Qiniseka ukuthi ilensi izofanelana nesisombululo kanye nosayizi wephikseli yenzwa.

I-MTF kanye ne-RI: I-MTF imele i-Modulation Transfer Function, kanti i-RI imele i-Relative Illumination. Zinqunywa ngesikhathi sokuklama, okubonisa ikhwalithi yokuthwebula ilensi. Ngamanye amazwi, ukuthi KUHLE kangakanani ongakubona. Uma kungakhiqizwa futhi kuhlanganiswe ngokucophelela, ijika langempela le-MTF kanye ne-RI lizoba ngaphansi kwalokho okwaklanywa. Ngakho-ke qiniseka ukuthi i-MTF kanye ne-RI yelensi ye-infrared ziyahlolwa ngaphambi kokuyithola.

Ukwemboza: Ngokuvamile ingxenye yangaphandle yelensi yenziwe nge-germanium, ethambile futhi kulula ukuyiklwebha. Ukwemboza okujwayelekile kwe-AR (anti-reflection) ngeke kusize kulokho, ukwemboza kwe-DLC (Diamond Like Carbon) noma i-HD (High Durable) kunganconywa ukuthi kusetshenziswe ngaphansi kwesimo esinzima. Kodwa sicela uqaphele ukuthi ukudluliselwa okuphelele kwelensi ye-infrared kuzoncishiswa ngesikhathi esifanayo. Ngakho-ke udinga ukulinganisela lezi zinto ezimbili ukuze ufeze ukusebenza okwamukelekayo.

Ukumelana Nokwethuka: Angizithandi ezinye izinhlelo zokusebenza zokuthatha izithombe zokushisa, isikopu sokushisa esifakwe esibhamini kumele sikwazi ukumelana nokudlidliza okukhulu okubangelwa ukudubula ngezibhamu. Yonke ilensi ye-infrared yesikopu sokushisa esiyinikezayo ingamelana nokumelana nokushaqeka okungaphezulu kuka-1200g.
