Ijisho rya Silicon (Si) rya Infrared rifite IR Anti-Reflection Coating

Ibisobanuro bigufi:

Indorerwamo za silicon (Si) zifite icyuma gikingira urumuri (IR anti-reflection)ni ibice by'urumuri byakozwe neza ku buryo bwa infrared optical systems zikenera ubushobozi bwo kohereza amakuru ku buryo bwo hejuru, ubushyuhe buhamye, no kwizerwa mu by'ikoranabuhanga. Hakoreshejwe silicon imwe ya crystal imwe ikora neza hamwe n'ikoranabuhanga rigezweho ryo gusiga infrared, izi lenses zikozwe neza kugira ngo zigabanye igihombo cy'urumuri no kongera imikorere y'urwego rwa sisitemu mu bikorwa bikomeye bya infrared.

Intangiriro Lens ya Si

Bitewe n’imiterere yayo ihamye yo kohereza amashusho ya infrared n’imiterere yayo myiza cyane, silikoni yabaye ibikoresho bikoreshwa cyane mu gushushanya amashusho ya infrared hagati. Iyo ihujwe n’ipamba rya IR AR ryakozwe neza, lenses za silikoni zitanga igisubizo gihendutse kandi cyiza cyane ku buryo bugezweho bwo gufata amashusho ya infrared no kumva amashusho.

Imiterere y'ibikoresho n'ibyiza by'imikorere ya Si Lens

Silikoni igaragaza uburyo bwo kohereza amakuru mu buryo buhoraho muri1.2–8 μmintera y'uburebure bw'umuraba kandi ikwiriye cyane cyane3–5 μm (MWIR)Imiterere yayo y'ibanze ituma lense za silikoni zigumana ubusugire bw'amaso n'ubw'imashini ndetse no mu bihe bigoye byo gukora.

Ibyiza by'ingenzi ku bikoresho birimo:

Ifite ubushyuhe bwinshi butuma ubushyuhe bushira neza
Imbaraga zikomeye za mekanike no kurwanya impanuka y'ubushyuhe
Uburemere buri hasi ugereranije na germanium, bituma sisitemu nto ikora neza
Ubudahangarwa bwiza ku bidukikije no ku mikorere ya shimi
Guhuza n'uburyo bwo gukora optique neza

Izi kamere zituma lenzi za silikoni ziba amahitamo meza kuri sisitemu za infrared zigomba gukora neza mu gihe kirekire cyangwa mu bushyuhe buhindagurika.

Igishushanyo mbonera cy'ubukorikori burwanya kugaragara kw'imirasire ya infrared Si lens

Kubera ko silikoni ifite igipimo cyo hejuru cyo kugarura urumuri, ubuso budatwikiriye bushobora guteza igihombo gikomeye cyo kugarura urumuri. Kugira ngo ibi bikemuke,irangi ririnda urumuri rw'infrarougezishyirwa ku buso bw'indorerwamo kugira ngo zongere imikorere myiza y'urumuri.

Igitambaro cya IR AR cyagenewe:

Gabanya Fresnel reflections kuri silicon-air interfaces
Ongera uburyo bwo kohereza amakuru neza mu gice cy’infrarouge
Kunoza uburyo ishusho igaragara neza, itandukaniro, no kumenya uburyo iboneka
Kuraho reflections zitaraboneka mu matsinda y'amatara

Imiterere y'imyambaro ishobora kunozwa ku rugero runaka rw'uburebure bw'umuraba nko3–5 μm (MWIR) or 8–12 μm (LWIR), ndetse no ku migozi yihariye ya infrared igenwa n'ibisabwa na sisitemu.

Igishushanyo mbonera cy'amaso n'imikorere ihindagurika. Lens ya Si

Indorerwamo za silicon infrared zifite IR AR coating ziboneka mu buryo butandukanye bwo kwerekana kugira ngo zishyigikire imiterere itandukanye ya sisitemu:

Indorerwamo za Plano-convex, plano-concave, bi-convex, na bi-concave lenses
Imiterere y'imiterere y'isi yose n'iy'isi yose
Irangi rirwanya urumuri ry'uruhande rumwe cyangwa uruhande rubiri rw'uruhande rw'imbere
Gusukura neza ubuso bugenzurwa n'imiterere yabwo n'ubugari bwayo

Imikorere y’inganda igenzurwa neza kugira ngo harebwe ko uburebure bw’inyuma, imiterere y’ubuso ihamye, n’imikorere y’ipamba ihamye. Imiterere yihariye ishyigikiwe n’umurambararo, ubunini, imiterere y’ipamba, ubushobozi bwo kwihanganira ibintu, n’imiterere y’ipamba.

Ahantu ho Gukoresha Serivisi

Indorerwamo za silicon zifite IR anti-reflection coating zikunze gukoreshwa muri:

Ishusho y'ubushyuhe n'uburyo bwo kureba bwa infrared
Ibikoresho byo gupima ubushyuhe n'ingufu bya infrared
Ibikoresho byo kugenzura no kugenzura inganda
Ishusho ya infrared spectroscopy n'ibikoresho byo muri laboratwari
Sisitemu zo kohereza na transmission ya laser ya infrared

Imikorere yazo iringaniye no kuramba kwazo bituma zikoreshwa mu bucuruzi no mu nganda.

Ibibazo Bikunze Kubazwa - Lens ya Silicon (Si) ifite IR Anti-Reflection Coating

1. Ni uruhe rugero rw'uburebure bw'urumuri rwa silikoni rukwiriye gukoreshwa mu bikorwa bya infrared?

Lense za silicon zitanga uburyo bwiza bwo kohereza amakuru ya infrared muri1.2–8 μmuburebure bw'uburebure bw'umurambararo kandi bukunze gukoreshwa mu3–5 μm (MWIR)umugozi. Silicon ntiyemerwa gukoreshwa mu buryo bugaragara cyangwa bugaragara bitewe nuko ikwirakwizwa gake muri utwo duce.

2. Kuki irangi rya IR ririnda kugaragara ari ngombwa kuri lenses za silicon?

Silicon ifite igipimo cyo kugarura urumuri kiri hejuru cyane, bigatuma ishusho y'urumuri igaragara cyane ku mboni zidapfutse.Irangi rirwanya ubwiza bw'urumuri (AR)bigabanya ibi bihombo byo kugarura urumuri, byongera uburyo bwo kohereza amakuru yose, kandi byongera itandukaniro ry'amashusho n'urusaku mu buryo bwa infrared optical systems.
