IiWindows zeMetallized Optical: Izixhobo ezingasetyenziswanga kwi-Precision Optics

Kwiinkqubo ezichanekileyo kunye neenkqubo ze-optoelectronic, amacandelo ahlukeneyo ngamnye adlala indima ethile, esebenza kunye ukufezekisa imisebenzi enzima. Ngenxa yokuba la malungu enziwe ngeendlela ezahlukeneyo, unyango lwawo olungaphezulu luyahluka. Phakathi kwezinto ezisetyenziswa kakhulu,iifestile zamehloyiza ngeendlela ezininzi zenkqubo. Iseti ebonakala ilula kodwa ibalulekile yileifestile ye-metalized optical-kungekhona kuphela "umgcini-sango" wendlela ye-optical, kodwa kunye yinyanisoumncediyokusebenza kwenkqubo. Makhe sihlolisise.

Yintoni ifestile ye-metalized optical-kwaye kutheni ifake isinyithi?

1) Inkcazo

Ngamafutshane, aifestile ye-metalized opticalyinxalenye ye-optical i-substrate yayo-ngokuqhelekileyo iglasi, i-silica edibeneyo, isafire, njl njl-inomaleko obhityileyo (okanye i-multilayer) yesinyithi (umzekelo, i-Cr, i-Au, i-Ag, i-Al, i-Ni) efakwe emaphethelweni ayo okanye kwiindawo ezichongiweyo zomphezulu ngokusebenzisa iinkqubo ze-vacuum ezichanekileyo ezifana ne-evaporation okanye i-sputtering.

Ukusuka kuhluzo olubanzi lwetaxonomy, iifestile ezinentsimbi zihayiIzihluzi zemveli "ze-optical". Izihluzi zeClassic (umzekelo, i-bandpass, i-long-pass) ziyilelwe ukusasaza ngokukhethayo okanye ukubonisa iibhendi ezithile ze-spectral, ukuguqula i-spectrum yokukhanya. Anifestile yamehlo, ngokuchaseneyo, ngokuyintloko ikhusela. Kufuneka igcineusulelo oluphezuluphezu kwebhendi ebanzi (umzekelo, VIS, IR, okanye UV) ngelixa ubonelelaukwahlulwa kokusingqongileyo kunye nokutywinwa.

Ngokuchanekileyo, ifestile enentsimbi yiudidi oluphantsi olulodwayefestile yamehlo. Umahluko wayo ulele kwii-metallization, enika imisebenzi iwindow eqhelekileyo ayinako ukubonelela.

2) Kutheni metallize? Iinjongo ezingundoqo kunye neenzuzo

Ukwambathisa icandelo elicacileyo ngegama ngentsimbi efipheleyo kunokuvakala ngathi kuchasene noko, kodwa lukhetho olunobulumko, oluqhutywa yinjongo. Ukwenziwa kweentsimbi ngokuqhelekileyo kwenza enye okanye ngaphezulu kwezi zilandelayo:

(a) Ukuphazamiseka koMbane (EMI) ukukhusela
Kwiinkqubo ezininzi ze-elektroniki kunye ne-optoelectronic, i-sensor sensors (umzekelo, i-CCD / CMOS) kunye ne-lasers zisengozini kwi-EMI yangaphandle-kwaye zinokukhupha ukuphazamiseka ngokwazo. Uluhlu oluqhubekayo, oluqhubekileyo lwensimbi kwifestile lunokusebenza njengeIkheji yaseFaraday, ukuvumela ukukhanya kudlule ngelixa uvala iindawo ezingafunekiyo zeRF/EM, ngaloo ndlela kuzinzisa ukusebenza kwesixhobo.

(b) Ukuqhagamshelwa kombane kunye nokubekwa phantsi
Umaleko we-metalized uyaqhuba. Ngokudibanisa isikhokelo kuyo okanye ngokuqhagamshelana nayo kwizindlu zentsimbi, unokwenza iindlela zombane zezinto ezifakwe kwicala langaphakathi lefestile (umzekelo, izifudumezi, izinzwa zobushushu, i-electrode) okanye ubophe ifestile emhlabeni ukuze uchithe i-static kunye nokuphucula ukukhusela.

(c) Ukutywinwa kweHermetic
Le yimeko yokusetyenziswa kwelitye lembombo. Kwizixhobo ezifuna ivacuum ephezulu okanye umoya ongasebenziyo (umzekelo, iityhubhu zelaser, iityhubhu zephotomultiplier, izinzwa ze-aerospace), ifestile mayidityaniswe kwipakethe yentsimbi eneisigxina, itywina elithembekileyo kakhulu. Ukusebenzisaukugquma, Ungqameko oluyintsimbi lwefestile ludityaniswe kwizindlu zentsimbi ukuze kuphunyezwe i-hermeticity engcono kakhulu kune-adhesive bonding, iqinisekisa uzinzo lwexesha elide lokusingqongileyo.

(d) Izikrolo kunye neemaski
Ukwenziwa kwesinyithi akufuneki kugqume umphezulu wonke; inokwenziwa ipateni. Ukubeka imaski eyenziwe ngentsimbi (umzekelo, isetyhula okanye isikwere) ichaza ngokuchanekileyo iindawo ecacileyo, ivimba ukukhanya okulahlekileyo, kwaye iphucula i-SNR kunye nomgangatho womfanekiso.

Apho kusetyenziswa iifestile ezinentsimbi

Enkosi kobu buchule, iifestile ezinentsimbi zisasazwa ngokubanzi naphi na apho iimeko zifuna khona:

• Ukhuseleko kunye ne-aerospace:abafuna imijukujelwa, iintlawulo zesathelayithi, iinkqubo ze-IR zomoya-apho ukungcangcazela, ukugqithiswa kwe-thermal, kunye ne-EMI eyomeleleyo ziyinto eqhelekileyo. Ukwenziwa kwesinyithi kuzisa ukhuseleko, ukutywinwa kunye nokukhuselwa.

• Umzi-mveliso okumgangatho ophezulu kunye nophando:i-laser enamandla kakhulu, i-particle detectors, i-vacuum viewports, i-cryostats-izicelo ezifuna ingqibelelo eqinileyo ye-vacuum, ukunyamezela kwemitha, kunye nokunxibelelana kombane okuthembekileyo.

• Inzululwazi yezonyango kunye nobomi:izixhobo ezinelaser ezidityanisiweyo (umz., ii-cytometers ezijikelezayo) ekufuneka zitywine umngxuma welaser ngelixa ukhulula umqadi.

• Unxibelelwano kunye neemvakalelo:iimodyuli ze-fiber-optic kunye ne-gas sensors ezixhamla kwi-EMI yokukhusela ukucoceka komqondiso.

Iimpawu eziphambili kunye neendlela zokukhetha

Xa ukhankanya okanye uvavanya iifestile zamehlo ezinentsimbi, gxininisa:

1. Izinto eziphathekayo-Imisela ukusebenza kwamehlo kunye nomzimba:

• BK7/K9 iglasi:yezoqoqosho; ifanelekile kokubonakalayo.

• Isilica edibeneyo:ukuhanjiswa okuphezulu ukusuka kwi-UV ukuya kwi-NIR; CTE ephantsi kunye nokuzinza okugqwesileyo.

• Isafire:iqine kakhulu, ikwazi ukumelana nokukrweleka, ikwazi ubushushu obuphezulu; Usetyenziso olubanzi lwe-UV-mid-IR kwiindawo ezirhabaxa.

• Si/Ge:ikakhulu kuband IR.

2. Umngxuma ocacileyo (CA)-Ingingqi iqinisekisiwe ukuhlangabezana nespekthi zamehlo. Iindawo ezinyityilisiweyo zihlala ngaphandle (kwaye zibe nkulu kune) eCA.

3. Uhlobo lwe-Metallization & ubukhulu-

• Crisoloko isetyenziselwa ukuvala ukukhanya kunye nesiseko sokuncamathelisa / sokubrawuza.

• Auibonelela nge-conductivity ephezulu kunye nokumelana ne-oxidation ye-soldering / brazing.
  Ubungqingqwa obuqhelekileyo: amashumi ukuya kumakhulu eenanometers, ezilungiselelwe ukusebenza.

4. Ugqithiso– Ipesenti yogqitho ngaphezulu kwebhendi ekujoliswe kuyo (λ₁–λ₂). Iifestile ezisebenza kakhulu zinokugqitha99%ngaphakathi kwebhendi yoyilo (kunye neengubo ezifanelekileyo ze-AR kwi-aperture ecacileyo).

5. Hermeticity-Kubalulekile kwiifestile eziqhagamshelweyo; ngokuqhelekileyo iqinisekiswa ngovavanyo lokuvuza kwe-helium, kunye namazinga angqongqo okuvuza afana< 1 × 10⁻⁸ cc/s(atm Yena).

6. Ukuhambelana kweBrazing– Isitaki sesinyithi kufuneka simanzi kwaye sibopheleleke kakuhle kwizihluzi ezikhethiweyo (umzekelo, i-AuSn, i-AgCu eutectic) kwaye imelane nokuhamba ngebhayisikile eshushu kunye noxinzelelo lomatshini.

7. Umgangatho womphezulu-Scratch-Dig (umz.,60-40okanye ngcono); amanani amancinci abonisa iziphene ezimbalwa/ezikhaphukhaphu.

8. Umfanekiso womphezulu-Ukutenxa komtyaba, okuchazwe ngokuqhelekileyo kumaza kubude obunikiweyo (umz.,λ/4, λ/10 @ 632.8 nm); amaxabiso amancinci athetha ukucaba okungcono.

Okukwintsusa

Iifestile zemetallized ze-optical zihlala kwi-nexus yeukusebenza kwamehlokwayeukusebenza koomatshini/kombane. Bahamba ngaphaya kokudluliselwa nje, basebenza njengeizithintelo ezikhuselayo, izikhuselo ze-EMI, ujongano lwe-hermetic, kunye neebhulorho zombane. Ukukhetha isisombululo esifanelekileyo kufuna isifundo sorhwebo lwenqanaba lenkqubo: Ngaba ufuna ukuqhuba? I-Brazed hermeticity? Yintoni ibhendi yokusebenza? Inzima kangakanani imithwalo yendalo esingqongileyo? Iimpendulo ziqhuba ukukhethwa kwe-substrate, istaki se-metallization, kunye nendlela yokucubungula.

Yiyo kanye le ndibaniselwanoukuchaneka kwesikali esincinci(amashumi e-nanometers yeefilimu zetsimbi zobunjineli) kunyeukomelela kwesikali esikhulu(ukumelana nokwahluka koxinzelelo kunye nojingi olunoburhalarhume) eyenza iifestile zentsimbi ezibonayo zibe yimfuneko"Ifestile ephezulu"—unxulumanisa ummandla othe-ethe obonakalayo kunye nezona meko zinzima zehlabathi.
