Filimu yotsutsana ndi kuwunikira ya AR yokhala ndi lenzi ya silicon yokhala ndi monocrystalline silicon

Filimu yoteteza kuwala kwa silicon yokhala ndi lenzi ya monocrystalline silicon yokhala ndi AR yophimbidwa ndi AR yoletsa kuwunikira Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Lenzi ya silicon yokhala ndi ma crystalline monocrystalline ndi chinthu chogwira ntchito bwino chochokera ku silicon ya monocrystalline (Si) yoyera kwambiri pogwiritsa ntchito ukadaulo wolondola wa kuwala ndi ukadaulo wophimba. Silicon ya monocrystalline ili ndi kuwala kwabwino kwambiri komwe kumafalikira mu infrared band (1.2-7μm), ndipo kuphatikiza ndi zophimba monga anti-reflection film (AR), high reflection film (HR) kapena fyuluta film, imatha kusintha kwambiri transmittance kapena reflection performance ya ma band enaake. Zogulitsazi zimagwiritsidwa ntchito kwambiri mu infrared imaging, laser optics ndi semiconductor detection.

Tumizani imelo kwa ife

Mawonekedwe

Makhalidwe a lenzi ya silicon yokutidwa:

1. Kugwira ntchito kwa kuwala:
Kuchuluka kwa ma transmittance: 1.2-7μm (pafupi ndi infrared mpaka mid-infrared), transmittance >90% mu 3-5μm atmospheric window band (pambuyo pa kupaka).
Chifukwa cha kuchuluka kwa refractive index (n≈ 3.4@4μm), filimu yotsutsa reflection (monga MgF₂/Y₂O₃) iyenera kupakidwa kuti ichepetse kutayika kwa reflection pamwamba.

2. Kukhazikika kwa kutentha:
Kuchuluka kwa kutentha kochepa (2.6×10⁻⁶/K), kukana kutentha kwambiri (kutentha kogwira ntchito mpaka 500℃), koyenera kugwiritsa ntchito laser yamphamvu kwambiri.

3. Kapangidwe ka makina:
Kulimba kwa Mohs 7, kukana kukanda, koma kufooka kwambiri, kumafuna chitetezo cha m'mphepete.

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

Magalasi a silicon okhala ndi zokutira:

(1) Dongosolo lojambula zithunzi za kutentha kwa infrared
Monga gawo lalikulu la magalasi a infrared (3-5μm kapena 8-12μm band) kuti aziyang'anira chitetezo, kuyang'anira mafakitale ndi zida zowonera usiku zankhondo.

(2) Dongosolo la kuwala la laser
CO₂ Laser (10.6μm): Lenzi yowunikira kwambiri ya ma resonator a laser kapena chiwongolero cha beam.

Laser ya fiber (1.5-2μm): Lenzi ya filimu yotsutsana ndi kuwunikira imawongolera magwiridwe antchito a coupling.

(3) Zipangizo zoyesera ma semiconductor
Chophimba cha infrared microscopic chothandizira kuzindikira zolakwika za wafer, cholimba ku dzimbiri la plasma (chitetezo chapadera chophimba chikufunika).

(4) zida zowunikira ma spectral
Monga gawo la spectral la Fourier infrared spectrometer (FTIR), ma transmittance ambiri ndi ma wavefront distortion ochepa amafunika.

Magawo aukadaulo:

Lenzi ya silicon yokhala ndi ma crystalline monocrystalline yakhala chinthu chofunikira kwambiri mu infrared optical system chifukwa cha kuwala kwake kwabwino kwambiri kwa infrared, kukhazikika kwa kutentha kwambiri komanso mawonekedwe ake ophikira omwe angasinthidwe. Ntchito zathu zapadera zimatsimikizira kuti ma lenzi amagwira ntchito bwino kwambiri mu laser, kuyang'anira ndi kujambula zithunzi.

Utumiki wa XKH Custom

XKH imapereka njira zonse zosinthira ma lens a silicon okhala ndi ma crystalline: Kuyambira kusankha substrate ya silicon yokhala ndi ma crystalline (resistivity >1000Ω·cm), kukonza bwino kwa kuwala (spherical/aspherical, surface accuracy λ/4@633nm), custom clothing (anti-reflection/high reflection/filter film, support multi-band design), mpaka kuyesa kokhwima (transmission rate, laser damage threshold, environmental reliability testing), support small batch (10 pieces) mpaka kupanga kwakukulu. Imaperekanso zikalata zaukadaulo (coating curves, optical parameters) ndi chithandizo chogulitsa pambuyo pogulitsa kuti zikwaniritse zofunikira za infrared optical systems.
