I-China Silicon Lens(Si ilensi) Yokukhiqiza Izicelo Nezimboni ze-Infrared |Ubude begagasi

Ilensi ye-Silicon(Si ilensi) yezinhlelo zokusebenza ze-infrared Isithombe Esifakiwe

I-Silicon Lens(Si lens) yezicelo ze-infrared

I-wavelength infraredinikeza i-silicon lens ngobukhulu obudumile ukusuka ku-10mm kuya ku-200 mm ububanzi.Usayizi welensi ongaphezu kuka-200mm nawo ungahlinzekwa uma ucelwa.Ukufakwa kwethu okujwayelekile kwe-AR kanye ne-DLC kuyifaneleka kakhulu ibhendi eku-3-5 micron.Ubude bokugxila bamalensi ethu bungalawulwa bufike ku-+/-1% ekubekezeleni, ukucaba kwendawo λ/4 @ 632.8nm kanye nokungajwayelekile kwendawo ngaphansi kuka-0.5 micron.

Omaka bomkhiqizo

Ulwazi lomkhiqizo:

I-Silicon lens iyilensi ebonakalayo eyenziwe nge-silicon.I-Silicon (Si) iwumsebenzi wekristalu ovame ukusetshenziswa kumasistimu okukhanya kwe-infrared asebenza kubhendi ye-spectral engu-3 ukuya ku-5µm.Inkomba yayo ye-refractive iseduze no-3.4 kulo lonke uhla.Inokuminyana okuphansi ngokuqhathaniswa phakathi kwezinto ezivamile ze-infrared, okuyingxenye kuphela ye-Ge, GaAs ne-ZnSe.Ngakho-ke impahla ye-silicon iyisinqumo esihle sohlelo olunokukhathazeka ngesisindo.I-silicon nayo ilukhuni futhi ishibhile kuneningi lezinto ezijwayelekile ze-infrared, yehlisa izindleko zezinto ezibonakalayo ngenkathi inyusa izindleko zokwenziwa ngasikhathi sinye.

I-Silicon ifaneleka kahle ekufakweni kwe-MWIR kodwa ngenxa yokumuncwa okuqinile ngaphezu kwama-micron ayi-6, ayifaneleki isicelo se-LWIR.Ingasetshenziswa futhi njenge-substrate yesibuko sokufakwa kwe-laser ngenxa ye-thermal conductivity, isisindo esilula, nobulukhuni.

I-Wavelength Infraredingakwazi ukukhiqiza ukwakheka okuhlukahlukene kwe-silicon lensindiza, i-concave, i-convex, indawo ye-aspheric kanye ne-diffractive.I-Silicon idume kakhulu kumasistimu asebenza endaweni ye-spectral engu-3-5µm, enezingubo eziphikisayo (i-AR coating), ukudluliswa okumaphakathi kungalethwa kufikela ku-98%.Singasebenzisa futhi 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 infraredikhiqiza ilensi yekhwalithi eyindilinga ne-aspheric silicon.Angagxila noma ahlukanise i-beam yokukhanya engenayo ukuze ahlangabezane nezimfuneko ezithile zesistimu ye-infrared.
