Ilensi ye-infrared yomfanekiso we-thermal umfanekiso wesibhamu

I-Wavelength Infrared ivelisa amashumi amawaka eelensi ze-infrared ze-Thermal Imaging Rifle Scopes minyaka le, ezithunyelwa kwiinkampani ezidumileyo ze-thermal scope kwihlabathi liphela.

I-thermal scope iyakwazi ukubona imizimba efudumeleyo kwindawo epholileyo ngokwendalo ngomahluko wayo wobushushu. Ngokungafaniyo ne-experienced night view scope yendabuko, ayidingi nkxaso yokukhanya okungasemva ukuze yenze umfanekiso obonakalayo. I-thermal scope ingasebenza imini nobusuku, inqumle umsi, inkungu, uthuli kunye neminye imiqobo yokusingqongileyo. Oku kwenza ukuba ibe luncedo ngokukodwa ekuzingeleni, ekufuneni nasekuhlanguleni, okanye kwimisebenzi yobuchule.

Ilensi ye-infrared yenye yezona zinto ziphambili kwi-thermal scope, edityaniswe ne-thermal sensor ukuguqula umfanekiso we-infrared ube yimiqondiso ye-elektroniki. Emva koko imiqondiso iguqulwa ibe ngumfanekiso obonakalayo ukuze uboniswe kwiscreen se-OLED samehlo abantu. Ukucaca, ukugqwetheka, ukukhanya komfanekiso wokugqibela; uluhlu lokufumanisa, ukuqatshelwa kunye nokuchonga; ukusebenza kwiimeko ezahlukeneyo zendalo, kunye nokuthembeka kwe-scope kuchaphazeleka ngokuthe ngqo yilensi ye-infrared. Kubaluleke kakhulu ukukhetha ilensi ye-infrared efanelekileyo ekuqaleni kwayo nayiphi na uyilo lwe-thermal scope.

Nangona ilensi ye-infrared efanelekileyo ibaluleke kakhulu kwi-scope efanelekileyo yobushushu, kukwakho nemiphumo ethile ebalulekileyo ekufuneka igxininiswe kuyo.

Ubude bokuGxila (FL) kunye ne-F#: Ubude bokuGxila kwelensi ye-infrared bumisela uluhlu lwe-DRI lwe-thermal scope. Ngamanye amazwi, ukuba ungabona kude kangakanani. I-25mm, 35mm, 50mm, 75mm zezona ziqhelekileyo ubude bokuGxila ezisetyenziswa kwi-thermal scope. I-F# yi-ratio yobude be-focal yenkqubo ukuya kububanzi be-entry pupil, F# = FL/D. Okukhona i-F# yelensi incinci, kokukhona i-entry pupil inkulu. Ukukhanya okungakumbi kuya kuqokelelwa yilensi ngelixa iindleko zinyuka ngaxeshanye. Ngokubanzi ilensi ene-F#1.0-1.3 ifanelekile ukusetyenziswa kwi-thermal scope.

Uhlobo lweSensor: Isensor ye-infrared ithatha isabelo esikhulu sexabiso lilonke le-scope yobushushu. Imisela ukuba ungabona UBANZI kangakanani nge-scope yobushushu. Qinisekisa ukuba ilensi iyahambelana nesisombululo kunye nobukhulu be-pixel yesensor.

I-MTF kunye ne-RI: I-MTF imele iModulation Transfer Function, kwaye i-RI imele iRelative Illumination. Zimiselwa ngexesha loyilo, nto leyo ebonisa umgangatho womfanekiso welensi. Ngamanye amazwi, indlela entle ngayo onokuyibona. Ukuba ayenziwa kwaye ihlanganiswe ngononophelo, i-MTF yokwenyani kunye ne-RI curve iya kuba ngaphantsi kuneyayilwe. Ngoko ke qiniseka ukuba i-MTF kunye ne-RI yelensi ye-infrared ziyavavanywa ngaphambi kokuba zifumaneke.

Ukwaleka: Ngokubanzi isiqwenga sangaphandle selensi senziwe nge-germanium, ethambileyo kwaye kulula ukuyikrwela. Ukwaleka okuqhelekileyo kwe-AR (anti-reflection) akuyi kunceda kuloo nto, ukwaleka kwe-DLC (Diamond Like Carbon) okanye i-HD (High Durable) kuyacetyiswa ukuba kusetyenziswe phantsi kweemeko ezinzima. Kodwa nceda uqaphele ukuba ukudluliselwa okupheleleyo kwelensi ye-infrared kuya kuncitshiswa ngaxeshanye. Ngoko ke kufuneka ulinganisele ezi zinto zimbini ukuze ufezekise ukusebenza okwamkelekileyo.

Ukumelana Nokushukuma: Andizithandi ezinye iinkqubo zokuthatha imifanekiso yobushushu, isikopu sobushushu esifakwe kwisibhamu kufuneka sikwazi ukumelana nokungcangcazela okukhulu okubangelwa kukudubula ngemipu. Zonke iilensi ze-infrared zesikopu sobushushu esizibonelelayo zinokufikelela kwi->1200g yokumelana nokushukuma.
