Ilensi yesilicon egqunywe ilensi ye-monocrystalline yesilicon isiko egqutywe ifilimu ye-AR echasene nomfanekiso obonakalayo

Inkcazelo emfutshane:

Ilensi ye-silicon edityanisiweyo ye-monocrystalline yinto esebenzayo ye-optical element esekelwe kwi-silicon ecocekileyo ye-monocrystalline (Si) ngokucokisekileyo optical processing kunye neteknoloji yokwambathisa. I-silicon ye-Monocrystalline inokuhanjiswa kokukhanya okugqwesileyo kwi-infrared band (1.2-7μm), kwaye idibaniswe neengubo ezifana nefilimu ye-anti-reflection (AR), ifilimu ebonisa ifilimu (HR) okanye ifilimu yokucoca, inokuphucula kakhulu ukuhanjiswa okanye ukubonakalisa ukusebenza kweebhendi ezithile. Iimveliso zisetyenziswa ngokubanzi kwiimaging ye-infrared, i-laser optics kunye nokufunyanwa kwe-semiconductor.

Iimbonakalo

Iimpawu ze-silicon lens ezigqunywe:

1. Ukusebenza kwamehlo:
Uluhlu lwe-Transmittance: 1.2-7μm (kufuphi ne-infrared ukuya kwi-infrared ephakathi), ukuhanjiswa> 90% kwibhanti yefestile ye-atmospheric ye-3-5μm (emva kokugquma).
Ngenxa yesalathisi esiphezulu se-refractive (n≈ 3.4@4μm), ifilimu echasene ne-reflection (efana ne-MgF₂ / Y₂O₃) kufuneka ifakwe ukuze kuncitshiswe ilahleko yokubonisa umphezulu.

2. Uzinzo lweThermal:
I-coefficient yokwandisa i-thermal ephantsi (2.6 × 10⁻⁶/K), ukumelana nobushushu obuphezulu (ubushushu bokusebenza ukuya kuthi ga kwi-500℃), ilungele ukusetyenziswa kwe-laser yamandla aphezulu.

3. Iimpawu zoomatshini:
Ubunzima be-Mohs 7, ukuchasana nokukrweleka, kodwa ubunkunkqele obuphezulu, bufuna ukhuseleko lomphetho.

4. Iimpawu zokugquma:
Customized anti-reflection film (AR@3-5μm), high reflection film (HR@10.6μm for CO₂ laser), bandpass filter film, etc.

Ukusetyenziswa kwelensi yesilicon egqunyiweyo:

(1) Inkqubo ye-infrared thermal imaging
Njengenxalenye engundoqo yeelensi ze-infrared (i-3-5μm okanye i-8-12μm band) yokubeka iliso lokhuseleko, ukuhlolwa kwemizi-mveliso kunye nezixhobo zokujonga ebusuku zomkhosi.

(2) Inkqubo yeLaser optical
I-CO₂ Laser (10.6μm) : I-lens ephezulu yokubonakalisa i-laser resonators okanye i-beam steering.

I-Fiber laser (1.5-2μm) : I-lens yefilimu ye-Anti-reflection iphucula ukusebenza kakuhle kokudibanisa.

(3) Izixhobo zokuvavanya i-semiconductor
Injongo ye-infrared microscopic yokuchongwa kwesiphene se-wafer, ukumelana ne-plasma corrosion (ukhuseleko olukhethekileyo lokugquma luyafuneka).

(4) izixhobo zokuhlalutya i-spectral
Njengenxalenye yembonakalo ye-Fourier infrared spectrometer (FTIR), ukuhanjiswa okuphezulu kunye nokugqwetheka okusezantsi komphambili wamaza kuyafuneka.

Imilinganiselo yobugcisa:

Ilensi ye-silicon edityanisiweyo ye-monocrystalline iye yaba yinto ephambili engenakubuyiselwa kwinkqubo ye-infrared optical ngenxa yokuhanjiswa kwayo kokukhanya kwe-infrared, ukuzinza okuphezulu kwe-thermal kunye neempawu zokwaleka ngokwezifiso. Iinkonzo zethu ezikhethekileyo zesiko ziqinisekisa ukusebenza kakuhle kweelensi kwi-laser, uhlolo kunye nokusetyenziswa kwemifanekiso.

Inkonzo ye-XKH yesiko

I-XKH inikezela ngenkqubo epheleleyo yokwenza ngokwezifiso iilensi ze-silicon ze-monocrystalline: Ukusuka kwi-monocrystalline silicon i-substrate ekhethiweyo (i-resistivity> 1000Ω · cm), i-optical processing echanekileyo (i-spherical / aspherical, ukuchaneka komphezulu λ/4@633nm), i-coating custom (anti-reflection / high reflection/filter transmission), ukuxhasa i-laser yoyilo olungqongqo, ukuvavanya ifilimu yokucoca, ukuvavanya i-laser uvavanyo lokuthembeka), xhasa ibhetshi encinci (iziqwenga ezili-10) kwimveliso enkulu. Ikwabonelela ngamaxwebhu obugcisa (i-coating curves, parameters optical) kunye nenkxaso emva kokuthengisa ukuhlangabezana neemfuno ezifunekayo zeenkqubo ze-infrared optical systems.
