Ilensi ye-Germanium(Ge lens) yezinhlelo zokusebenza ze-infrared

I-Wavelength infrared inikeza ilensi yegermanium ngosayizi abadumile ukusuka ku-10m m ukuya ku-200 mm ububanzi.Usayizi welensi ongaphezu kuka-200mm nawo ungahlinzekwa kodwa uma kucatshangelwa ukuminyana okuphezulu kwezinto ze-germanium, kungaba nzima kakhulu kumasistimu ajwayelekile e-infrared.Ukufakwa kwethu okujwayelekile kwe-AR ne-DLC kuyifaneleka kakhulu ibhendi eku-3-5 noma 8-12 micron.Ubude obugxilile bamalensi ethu bungalawulwa bufike ku-+/-1% ekubekezeleni, ukucaba kwendawo λ/4 @ 632.8nm kanye nokungajwayelekile kwendawo ngaphansi kuka-0.5 micron.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Ulwazi lomkhiqizo:

Ilensi yeJalimane iyilensi yokubona eyenziwe nge-germanium.I-Gerinium (Ge) iwumsebenzi wekristalu onenkomba ephakeme kakhulu ye-refractive (4.002@11µm) yezinto ezisetshenziswa kakhulu ze-infrared.Iphinde ibe nokuhlakazeka okuphansi ngokuqhathaniswa, ubulukhuni obuphezulu kanye nokuminyana.Ngenxa yobubanzi bayo bokudlulisa okubanzi (ngaphezu kuka-45% kubhendi ye-micron engu-2-12) kanye ne-opaque ku-UV nokukhanya okubonakalayo, i-Germanium ikufanelekela kahle ukusetshenziswa kwe-IR njengamasistimu wokuthwebula izithombe ezishisayo, ukusetshenziswa kwenkundla ye-infrared namathuluzi okuhlaziya ngokunemba.

I-Germanium nayo ingaphansi kwe-thermal runaway.Ngokukhula kwezinga lokushisa, ukumuncwa kukhula ngokushesha okukhulu.Ngenxa yalo mphumela wokubaleka okushisayo, ilensi ye-germanium ayifanele ukusetshenziswa emazingeni okushisa angaphezu kuka-100°C.

I-Wavelength Infrared ingakha ukwakheka okuhlukahlukene kwelensi ye-germanium enendiza, i-concave, i-convex, i-aspheric kanye nezindawo ezihlukile.I-Germanium idume kakhulu kumasistimu asebenza endaweni ye-spectral engu-3-5 noma engu-8-12µm, enama-anti-reflective coating (i-AR coating), ukudluliswa okumaphakathi kungase kulethwe kufike ku-97.5-98.5% kuncike kumkhawulokudonsa wokumboza.Futhi singafaka i-carbon-coating efana nedayimane (i-DLC coating) noma i-high durable coating (i-HD coating) endaweni yelensi ukuze sinikeze ukuvikeleka okwengeziwe ngokumelene nokuklwebheka nomthelela.

I-Wavelength infrared ikhiqiza ilensi ye-germanium eyindilinga eyikhwalithi eyikhwalithi.Angakwazi ukugxila noma ahlukanise i-beam yokukhanya engenayo ukuze ahlangabezane nezimfuneko ezithile zesistimu ye-infrared.Uhlelo lokusebenza kungaba isithombe esishisayo, i-thermograph, i-beam collimating, ukuhlaziywa kwe-spectrum nokunye.

Imininingwane:

Okubalulekile I-Germany(Ge)
Ububanzi 10mm-300mm
Isimo I-Spherical noma i-Aspheric
