I-silicon (Si)
Amalensi e-Plano-Convex

Amalensi e-Plano-convex (PCX) anobude bokugxila obuphozithivu futhi angasetshenziswa ukugxilisa i-collimated beam endaweni egxile emuva, ukungqubuzana kokukhanya okuvela kumthombo wephoyinti, noma ukunciphisa i-engeli ephambukayo yomthombo ophambukayo.Ukuze unciphise ukwethulwa kwe-spherical aberration, umthombo wokukhanya ohlanganisiwe kufanele ube isigameko endaweni egobile yelensi uma usebenzisa i-PCX ukuze ugxilise umthombo wokukhanya ogqagqene;Ngokufanayo, imisebe yokukhanya ephambukayo kufanele ibe yisigameko endaweni epulaniwe yelensi ye-PCX lapho ingqubuzana nomthombo wokukhanya.Lawa ma-lens asetshenziswa ezinhlelweni ze-conjugate ezingapheli futhi ezinomkhawulo.

Lapho unquma phakathi kwe-plano-convex lens kanye ne-bi-convex lens, zombili ezidala ukuthi ukukhanya kwesigameko esihlanganisiwe kuhlangane, kuvamise ukufaneleka kakhulu ukukhetha ilensi ye-plano-convex uma ukukhuliswa okuphelele okufunayo kungaphansi kuka-0.2 noma kukhulu kuno-0.2 noma kukhulu kuno-0.2 5. Phakathi kwalawa manani amabili, amalensi ama-bi-convex ngokuvamile ayakhethwa.

I-Silicon inikeza i-conductivity ephezulu ye-thermal kanye ne-low density.Nokho inebhande eliqinile lokumunca kuma-microns angu-9, ayifanele ukusetshenziswa nezinhlelo zokusebenza zokudlulisela i-CO2 laser.I-Paralight Optics inikeza Amalensi e-Silicon (Si) e-Plano-Convex ayatholakala nge-broadband AR coating elungiselelwe ububanzi obungama-3 µm kuya ku-5 μm obufakwe kuzo zombili izindawo.Lokhu kunamathela kunciphisa kakhulu ukubukeka kwangaphandle kwe-substrate, kunikeze ukudluliswa okuphezulu kanye nokumunca okuncane kulo lonke uhla lwe-AR.Hlola Amagrafu ukuze uthole izinkomba zakho.
