Magirazi eMWIR

Lenzi ye infrared yepakati pemafungues (Lenzi yeMWIRes) zvinhu zvakakosha zvinoshandiswa mumhando dzakasiyana-siyana dzinoda thermal imaging, dzakadai sekutarisa, kuwana chinangwa, uye thermal analysis. Magirazi aya anoshanda munzvimbo ye mid-wave infrared ye electromagnetic spectrum, kazhinji iri pakati pe 3 ne 5 microns (Lenzi ye3-5um), uye zvakagadzirirwa kuti dziratidze mwaranzi ye infrared pa detector array.
Magirazi eMWIR anogadzirwa nezvinhu zvinogona kutumira uye kutarisisa IR radiation munzvimbo yeMWIR. Zvinhu zvinowanzoshandiswa kumagirazi eMWIR zvinosanganisira germanium, silicon, uye chalcogenide. Germanium ndiyo inonyanya kushandiswa kumagirazi eMWIR nekuda kwe refractive index yayo yakakwira uye hunhu hwakanaka hwekutumira muhuwandu hweMWIR.
Lenzi yeMWIR inouya nemagadzirirwo akasiyana-siyana uye magadzirirwo, zvichienderana nekushandiswa kwayo. Imwe yemagadzirirwo akajairika i lenzi yakapfava yeplano-convex, ine nzvimbo imwe yakati sandara uye imwe nzvimbo yakapfava. Lenzi iyi iri nyore kugadzira uye inoshandiswa mumashandisirwo akawanda apo panodiwa sisitimu yekufungidzira. Mamwe magadzirirwo anosanganisira ma lenzi maviri, ane ma lenzi maviri ane ma indices akasiyana e refractive, uye ma lenzi e zoom, anogona kugadzirisa urefu hwe focal kuti akwanise kuwedzera kana kuburitsa chinhu.
Magirazi eMWIR zvinhu zvakakosha mumasisitimu akawanda emifananidzo anoshandiswa mumaindasitiri akasiyana-siyana. Mumauto, magirazi eMWIR anoshandiswa mumasisitimu ekutarisa, masisitimu ekutungamira zvombo, uye masisitimu ekuwana chinangwa. Mumaindasitiri, magirazi eMWIR anoshandiswa mukuongorora kupisa uye masisitimu ekudzora mhando. Mukurapa, magirazi eMWIR anoshandiswa mumifananidzo inopisa yekuongorora kwete kungopinda mumuviri.
Chimwe chinhu chakakosha pakusarudza lenzi yeMWIR ihurefu hwayo hwefocal. Hurefu hwefocal hwelenzi hunosarudza daro riri pakati pelenzi ne detector array, pamwe nehukuru hwemufananidzo unogadzirwa. Semuenzaniso, lenzi ine focal length pfupi ichagadzira mufananidzo mukuru, asi mufananidzo hauzove netsananguro yakawanda. Lenzi ine focal length yakareba ichagadzira mufananidzo mudiki, asi mufananidzo uchava netsananguro yakawanda, sengeLenzi ye50mm MWIR.

Chimwe chinhu chakakosha kufunga nezvacho imhanyo yekumhanya kwelenzi, iyo inotsanangurwa nenhamba yayo ye f. Nhamba ye f inhamba yehuwandu hwe focal length nedhayamita yelenzi. Lenzi ine nhamba ye f yakaderera inokurumidza, zvichireva kuti inogona kubata chiedza chakawanda munguva pfupi, uye inowanzo shandiswa mumamiriro ekunze asina chiedza chakawanda.
Mukupedzisa, malenzi eMWIR chinhu chakakosha mumasisitimu akawanda emifananidzo anoshandiswa mumaindasitiri akasiyana-siyana. Akagadzirwa kuti aise infrared radiation pa detector array uye anouya mumhando dzakasiyana-siyana dzemagadzirirwo, zvichienderana nekushandiswa kwacho.
