Coated silicon lens monocrystalline silicon kev cai coated AR anti-reflection zaj duab xis
Cov yam ntxwv ntawm lub lens silicon coated:
1. Kev ua tau zoo ntawm qhov muag:
Kev sib kis tau ntau yam: 1.2-7μm (nyob ze infrared mus rau nruab nrab infrared), kev xa tawm > 90% hauv 3-5μm atmospheric window band (tom qab txheej).
Vim yog qhov ntsuas refractive siab (n≈ 3.4@4μm), ib daim zaj duab xis tiv thaiv kev cuam tshuam (xws li MgF₂/Y₂O₃) yuav tsum tau plated kom txo qhov poob ntawm qhov cuam tshuam ntawm qhov chaw.
2. Kev ruaj khov ntawm cua sov:
Cov coefficient thermal expansion qis (2.6 × 10⁻⁶ / K), tiv taus kub siab (kub ua haujlwm txog li 500 ℃), tsim nyog rau kev siv laser muaj zog siab.
3. Cov khoom siv kho tshuab:
Mohs hardness 7, khawb tsis kam, tab sis brittleness siab, xav tau kev tiv thaiv ntug chamfering.
4. Cov yam ntxwv ntawm txheej:
Customized anti-reflection film (AR@3-5μm), high reflection film (HR@10.6μm for CO₂ laser), bandpass filter film, etc.
Daim ntawv thov lens silicon coated:
(1) Lub tshuab thaij duab kub infrared
Ua ib feem tseem ceeb ntawm cov iav infrared (3-5μm lossis 8-12μm band) rau kev saib xyuas kev ruaj ntseg, kev tshuaj xyuas kev lag luam thiab cov khoom siv pom kev hmo ntuj tub rog.
(2) Lub tshuab kho qhov muag laser
CO₂ Laser (10.6μm): Lub lens reflector siab rau cov resonators laser lossis lub beam steering.
Fiber laser (1.5-2μm): Lub lens tiv thaiv kev cuam tshuam ua rau kev sib txuas ua haujlwm zoo dua.
(3) Cov khoom siv kuaj semiconductor
Lub hom phiaj infrared microscopic rau kev kuaj pom qhov tsis zoo ntawm wafer, tiv taus plasma corrosion (xav tau kev tiv thaiv txheej txheem tshwj xeeb).
(4) cov cuab yeej ntsuas spectral
Raws li ib feem ntawm Fourier infrared spectrometer (FTIR), yuav tsum muaj kev xa tawm siab thiab kev cuam tshuam nthwv dej tsawg.
Cov kev tsis txawj:
Lub lens monocrystalline silicon uas muaj txheej txheej tau dhau los ua ib qho tseem ceeb hauv lub tshuab kho qhov muag infrared vim nws muaj lub teeb infrared zoo heev, kev ruaj khov thermal siab thiab cov yam ntxwv ntawm kev txheej txheej uas hloov tau. Peb cov kev pabcuam tshwj xeeb ua kom ntseeg tau tias cov lens ua haujlwm zoo tshaj plaws hauv laser, kev tshuaj xyuas thiab kev siv duab.

XKH kev pabcuam tshwj xeeb
XKH muaj kev hloov kho tag nrho cov txheej txheem ntawm cov iav monocrystalline silicon coated: Txij li kev xaiv cov khoom siv monocrystalline silicon substrate (resistivity >1000Ω·cm), kev ua tiav optical precision (spherical/aspherical, surface accuracy λ/4@633nm), kev txheej txheem tshwj xeeb (anti-reflection/high reflection/filter film, txhawb nqa ntau-band tsim), mus rau kev sim nruj (transmission rate, laser damage threshold, environmental reliability testing), txhawb nqa cov khoom me me (10 daim) mus rau kev tsim khoom loj. Nws kuj muab cov ntaub ntawv pov thawj (coating curves, optical parameters) thiab kev txhawb nqa tom qab muag kom ua tau raws li qhov xav tau ntawm infrared optical systems.
