Isici se-Optical - iwindi lokukhanya

Iwindi le-Optical lisetshenziselwa ukuhlukanisa indawo ezungezile nhlangothi zombili, njengokuhlukanisa ingaphakathi nengaphandle lensimbi, ukuze ingaphakathi nengaphandle lensimbi liqhelelane, ngaleyo ndlela kuvikelwe amadivayisi angaphakathi.Kuyinto eyisisekelo ye-optical kanye ne-optical flat plate.Ayishintshi ukukhuliswa kwe-optical futhi ithinta kuphela indlela yokubona endleleni yokukhanya.

01 λ/ 4, λ/ 10 Ukukhanya okubonakalayoiwindi optical

iminyaka emi-5 (1)

Ipuleti yefasitela iyipuleti yendiza ehambisanayo, evame ukusetshenziswa njengefilimu evikelayo yenzwa ye-elekthronikhi noma umtshina wemvelo yangaphandle.Izinketho zefilimu ezingabonakali zifaka i-UV, i-VIS, i-NIR, ne-SWIR.I-Barium fluoride (BaF2), i-calcium fluoride (CaF2), i-zinc sulfide (ZnS), i-zinc selenide (ZnSe) noma i-silicon (Si) i-germanium (Ge) ifanele ukusetshenziswa kwe-infrared, kuyilapho i-quartz ehlanganisiwe nesafire kulungele ukusetshenziswa kwe-ultraviolet.

02 I-K9 enembayo ephezulu enezinhlangothi ezimbiliamafulethi

iminyaka emi-5 (2)

Amafulethi okukhanya angasetshenziswa njengendiza evamile ukuze kutholwe futhi kukhonjwe iphutha lokucaba kanye nokusebenza kokugeleza kwezinye izingxenye ezipholishelwe kakhulu.Inobucwebe bokunemba okuphezulu futhi ngokuvamile isetshenziswa iyodwa.Umfanekiso ongaphezulu: λ/ 10 kanye no-λ/ 20 Izinhlobo ezimbili.

 03 Iwindi le-wedge ye-K9 enembayo ephezulu

iminyaka emi-5 (3)

Izindiza ezimbili zewindi le-wedge zine-engeli efakiwe engu-31arc minute.Izindiza ezimbili ezingahambelani zingagwema umphumela wokuphazamiseka (umphumela we-Etalon) obangelwa ukukhanya okuveziwe okuvela endaweni engaphambili nangemuva yefasitela eliphezulu lokufana, futhi zingagwema nokuzinza okubi kokuphuma kwe-laser kanye nokugxuma kwemodi okubangelwa ukuphazamiseka kokubona. impendulo ye-laser resonator.

04 Ikhava ye-K9 Spherical 

Isembozo esiyindilinga iwindi lokuvikela elimise okwegobolondo le-hemispherical, elivame ukusetshenziswa ekusetshenzisweni kokukhanya kwesigameko esikhulu sebanga le-engeli, njengezitholi, izinzwa ezibonakalayo nezinye izinhlelo zokusebenza.

iminyaka emi-5 (4)

☆ Umhlahlandlela wokukhetha wewindi le-optical: Ukukhetha iwindi elifanele kubalulekile empumelelweni yohlelo lokusebenza.Izici eziyinhloko okufanele zicatshangelwe zihlanganisa: izinto ze-substrate, inqubo yokugqoka, ukunemba kwe-optical kanye nemishini.Esinye isisho singabuye sibe: i-substrate, ukucaciswa, ukudlulisa, ukunemba kwendawo, ukuhambisana, umkhawulo wokulimala kwe-laser neminye imingcele ehlobene. 

1 -I-substrate impahla

Ukukhethwa kwezinto ze-substrate ikakhulukazi kuhlanganisa ubude begagasi, inkomba ye-refractive, i-coefficient yokuhlakazeka, ukuminyana, i-thermal expansion coefficient, izinga lokushisa elithambile, ubulukhuni be-Knoop, njll. Izinto zamawindi ezivame ukusetshenziswa ku-ultraviolet ebonakalayo eduze nebhendi ye-infrared zihlanganisa i-magnesium fluoride, i-barium fluoride, ingilazi ye-k9 kanye i-quartz.I-calcium fluoride, i-silicon, i-germanium, i-zinc sulfide, i-zinc selenide nengilazi ye-chalcogenide ivame ukusetshenziswa phakathi namabhande e-infrared aphakathi nendawo.

I-2 - Ukunemba kwe-Optical kanye nemishini

Ukucaba komhlaba: kusetshenziselwa ukukala ukuthi ingaphezulu lewindi liyisicaba kangakanani.Ngokuvamile kukalwa ngokuhlobene negagasi elingu-632.8nm;Ukucaba kwegagasi elingu-1/10 kulingana nokucaba okungu-632.8.Ngokuvamile, i-1/10 wave noma ucezu lwefasitela olungcono luncanyelwa i-laser, futhi ucezu lwefasitela olu-1/4 noma olungcono lukhethwa ezinhlelweni zokusebenza ze-imaging;Ukukhanyisa nokutholwa kulungele izingcezu zewindi ngokunemba okuphansi. 

Ukufana: Izinga lokuchezuka kokufana phakathi kwezindawo ezimbili zewindi le-optical.Ngokuvamile, ucezu lwefasitela oluhambisana kakhulu luyadingeka ukuze kuthathwe izithombe;I-parallelism ephansi isetshenziselwa ukusetshenziswa kwe-laser;Ukufana ngokuvamile akudingekile ukuze kukhanye futhi kubonakale. 

Ikhwalithi yobuso: Ibhekisela ekuhlolweni kokulimala okungaphezulu, ngokuvamile okumelelwa yizibalo ezimbili, enye “iwukuklwebha” kanti enye “iwumgodi”.Ngokusebenza.Ikhwalithi ephezulu ye-10-5 / 20-10 inzima ukuyibona, futhi ivame ukusetshenziswa nge-laser;40-20 akulula ukubona, ngokuvamile esetshenziselwa izithombe;I-60-40 ijwayelekile futhi ifanele ukutholwa nokukhanyisa. 

3 - Ukukhetha i-coating

Amapuleti amafasitela avame ukumbozwa ngezimbotshana ezivimbela ukukhanya ukuze kuncishiswe ukulahlekelwa kokubonakala kwendawo futhi enze ukukhanya kungene ngokuphelele ku-substrate.Ngokuvamile, kunezinhlobo ezintathu zokumbozwa kwe-antireflection: i-antireflection yongqimba olulodwa, i-broadband antireflection coatings kanye ne-V yohlobo lwe-antireflection.Lezi zinhlobo ezintathu zamafilimu zihlukile ezicini ze-spectral, ububanzi bohlelo lokusebenza, izinto zokugqoka, ubunzima benqubo kanye nezindleko zokumboza.
