Silicon Lens (Si lens) ya Infrared Applications

Magalasi a silicon ndi mandala owoneka bwino opangidwa ndi silicon.Silicon (Si) ndi chinthu cha crystalline chomwe chimagwiritsidwa ntchito kwambiri pamakina a infrared optical omwe amagwira ntchito mu 3 mpaka 5µm spectral band.Mndandanda wake wa refractive uli pafupi ndi 3.4 mumtundu wonsewo.Ili ndi kachulukidwe kakang'ono pakati pa zida za infuraredi wamba, zomwe ndi theka la Ge, GaAs ndi ZnSe.Chifukwa chake zinthu za silicon ndizosankha bwino pamakina omwe ali ndi nkhawa.Silicon imakhalanso yolimba komanso yotsika mtengo kuposa zida zambiri za infrared, kuchepetsa mtengo wazinthu ndikuwonjezera mtengo wopanga nthawi imodzi.

Silicon ndiyoyenera kugwiritsa ntchito MWIR koma chifukwa cha kuyamwa mwamphamvu pamwamba pa 6 micron, siyoyenera kugwiritsa ntchito LWIR.Itha kugwiritsidwanso ntchito ngati gawo lagalasi lopangira laser chifukwa cha kutentha kwake, kulemera kwake, komanso kuuma kwake.

Wavelength Infraredamatha kupanga mawonekedwe osiyanasiyana a lens ya siliconndege, concave, convex, aspheric ndi diffraactive pamwamba.Silicon ndiyodziwika kwambiri pamakina omwe akugwira ntchito m'chigawo cha 3-5µm chowoneka bwino, chokhala ndi zokutira zotsutsa (AR coating), kufalikira kwapakati kumatha kubweretsedwa mpaka 98%.Tithanso kuyika zokutira ngati diamondi (zopaka za DLC) kapena zokutira zolimba kwambiri (zopaka za HD) pamagalasi kuti titetezere ku kukanda ndi kukhudzidwa.

Wavelength infraredamapanga lens ya silicon yamtundu wapamwamba komanso yowoneka bwino.Amatha kuyang'ana kapena kusiyanitsa kuwala komwe kukubwera kuti akwaniritse zofunikira za infrared system.
