Silicon Lens (Si lens) rau kev siv Infrared

Silicon lens yog optical lens ua los ntawm silicon.Silicon (Si) yog cov khoom siv crystalline uas feem ntau siv hauv infrared optical systems ua haujlwm hauv 3 txog 5µm spectral band.Nws qhov refractive index yog nyob ze 3.4 thoob plaws qhov ntau.Nws muaj qhov sib piv qis ntawm cov khoom siv infrared, uas tsuas yog ib nrab ntawm Ge, GaAs thiab ZnSe.Yog li cov khoom siv silicon yog qhov kev xaiv zoo tshaj plaws rau qhov system nrog kev txhawj xeeb txog qhov hnyav.Silicon kuj tseem nyuaj thiab pheej yig dua li feem ntau ntawm cov khoom siv infrared, txo cov nqi khoom thaum nce tus nqi fabrication tib lub sijhawm.

Silicon yog zoo haum rau MWIR daim ntawv thov tab sis vim muaj zog nqus siab tshaj 6 micron, nws tsis haum rau LWIR daim ntawv thov.Nws kuj tuaj yeem siv los ua daim iav substrate rau daim ntawv thov laser vim nws thermal conductivity, lub teeb yuag, thiab hardness.

Lub wavelength infraredtuaj yeem tsim ntau yam duab ntawm silicon lens nrogdav hlau, concave, convex, aspheric thiab diffractive nto.Silicon yog nrov tshaj plaws rau cov tshuab ua haujlwm hauv thaj tsam 3-5µm spectral, nrog cov txheej txheem tiv thaiv kev cuam tshuam (AR txheej), qhov nruab nrab kis tau tuaj yeem nqa mus txog 98%.Peb kuj tuaj yeem siv pob zeb diamond zoo li cov pa roj carbon txheej (DLC txheej) lossis cov txheej txheem siab ruaj khov (HD txheej) ntawm lub ntsej muag lo ntsiab muag los muab kev tiv thaiv ntxiv tiv thaiv khawb thiab cuam tshuam.

Lub wavelength infraredmanufactures zoo kev cai spherical thiab aspheric silicon lens.Lawv tuaj yeem ua kom pom tseeb lossis sib txawv ntawm lub teeb ci tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm qhov system infrared.
