Nhanganyaya Lenzi yeSi

Nekuda kwehunhu hwayo hwe infrared transmission hwakagadzikana uye hunhu hwayo hwakanaka hwepanyama, silicon yave chinhu chinoshandiswa zvakanyanya pakugadzira magadzirirwo e optical e mid-infrared. Kana ikasanganiswa ne IR AR coating yakagadzirwa zvakanaka, ma lenzi e silicon anopa mhinduro inodhura uye inoshanda zvakanyanya kune masisitimu emazuva ano e infrared imaging uye sensing.

Hunhu hwezvinhu uye Mabhenefiti ekushanda kweSi Lens

Silicon inoratidza kutumirwa kwe infrared nguva dzose mukati me1.2–8 μmhuwandu hwewavelength uye inonyanya kukodzera3–5 μm (MWIR)mashandisirwo ayo. Hunhu hwayo hwepanyama hunoita kuti magirazi esilicon arambe akagadzikana nemaziso kunyangwe mumamiriro ezvinhu akaoma ekushanda.

Zvakanakira zvinhu zvikuru zvinosanganisira:

Kupisa kwakanyanya kunofambisa kupisa zvakanaka
Simba rakasimba remakanika uye kuramba kupisa
Huremu hwakaderera kana tichienzanisa negermanium, zvichiita kuti pave nekugadzirwa kwesystem diki
Kugadzikana kwakanaka kwezvakatipoteredza uye makemikari
Kuenderana nemaitiro ekugadzira maoptical akarurama

Hunhu uhwu hunoita kuti magirazi esilicon ave sarudzo yakanaka kune masisitimu einfrared anofanira kushanda zvakanaka kwenguva yakareba kana munzvimbo dzinochinja-chinja tembiricha.

Dhizaini yeInfrared Anti-Reflection Coating Si lens

Nekuti silicon ine refractive index yakakwira, nzvimbo dzisina kuputirwa dzinogona kukonzera kurasikirwa kukuru kwe reflection. Kuti tigadzirise izvi,machira ekudzivirira kuratidzira kwe infraredzvinoshandiswa panzvimbo dzemalenzi kuti zvivandudze kushanda zvakanaka kwemaziso.

Kupfeka kweIR AR kwakagadzirirwa:

Deredza kuratidzwa kweFresnel panzvimbo dzesilicon-air interfaces
Wedzera kutumirwa kunobudirira kuburikidza nebhendi reinfrared rakanangwa
Kuvandudza kujeka kwemufananidzo, kusiyana, uye kunzwisisika kwekuonekwa
Dzvinyirira kuratidzwa kwakarasika mukati memagungano e optical

Magadzirirwo ekuputira anogona kugadziriswa kuti akwanise kuenderana nehukuru hwewavelength hwakadai se3–5 μm (MWIR) or 8–12 μm (LWIR), pamwe chete nemabhendi einfrared akagadzirwa zvinoenderana nezvinodiwa nesystem.

Kugadzira uye Kuchinja-chinja kweOptical Design Si lens

Magirazi e silicon infrared ane IR AR coating anowanikwa mumhando dzakasiyana dze optical configurations kuti atsigire magadzirirwo akasiyana-siyana esystem:

Magirazi ePlano-convex, plano-concave, bi-convex, uye bi-convex lenses
Majometri akatenderera uye akagadzirwa nemaoko
Kuvhara kweIR kunodzivirira kufungisisa kwedivi rimwe chete kana maviri
Kupukuta kwakanyatsonaka kwechimiro chepamusoro chakadzorwa uye chakakombama

Maitiro ekugadzira anodzorwa nokungwarira kuti ave nechokwadi chekuti urefu hwefocal, kururama kwenzvimbo, uye mashandiro ecoatings anotsigirwa nedhayamita, ukobvu, kutenderera, kushivirira, uye zvinodiwa zvecoatings.

Nzvimbo dzeKushandisa

Magirazi esilicon ane IR anti-reflection coating anowanzoshandiswa mu:

Kufungidzira kwekupisa uye masisitimu ekuona kweinfrared
Midziyo yekuona nekuyeresa tembiricha ye infrared
Midziyo yekutarisa nekuongorora yeindasitiri
Infrared spectroscopy uye zvishandiso zverabhoritari
Masisitimu ekutumira nelaser ye infrared uye optical transmission

Kushanda kwavo kwakaringana uye kugara kwenguva refu kunoita kuti vakwanise kushandiswa mumabasa e infrared nemaindasitiri.
