Isilicon (Si)
IiLensi zePlano-Convex

Iilensi zePlano-convex (PCX) zinobude bojoliso obulungileyo kwaye zingasetyenziselwa ukujolisa umqadi odityanisiweyo ukuya kwindawo ekugxilwe kuyo ngasemva, ukudibanisa ukukhanya ukusuka kwindawo yomthombo, okanye ukunciphisa i-engile ephambukayo yomthombo ophambukayo.Ukunciphisa ukuqaliswa kwe-spherical aberration, umthombo wokukhanya odibeneyo kufuneka ube sesiganeko kwindawo egobileyo ye-lens xa usebenzisa i-PCX ukugxila kumthombo wokukhanya odibeneyo;Ngokufanayo, imitha yokukhanya ephambukayo kufuneka ibe sehlo kumphezulu ocwangcisiweyo welensi yePCX xa kungqubana indawo yomthombo wokukhanya.Ezi lens zisetyenziswa kwi-conjugate applications engenasiphelo kunye nesiphelo.

Xa uthatha isigqibo phakathi kwelensi yeplano-convex kunye ne-bi-convex lens, zombini ezibangela ukuba ukukhanya kwesiganeko esidityanisiweyo kuhlangane, kudla ngokufaneleka ngakumbi ukukhetha iplano-convex lens ukuba ulwandiso olufunekayo lungaphantsi kwe-0.2 okanye lukhulu kuno 5. Phakathi kwala maxabiso mabini, iilensi ze-bi-convex zikhethwa ngokubanzi.

I-silicon inikezela nge-conductivity ephezulu ye-thermal kunye noxinzelelo oluphantsi.Nangona kunjalo inebhendi eyomeleleyo yokufunxa kwi-9 microns, ayifanelekanga ukusetyenziswa kunye ne-CO2 ye-laser transmission applications.IParalight Optics ibonelela ngeeLensi zeSilicon (Si) zePlano-Convex ziyafumaneka nge-broadband AR yokugquma elungiselelwe i-3 µm ukuya kwi-5 μm uluhlu lokubonwayo olufakwe kuyo yomibini imiphezulu.Olu gquba lunciphisa kakhulu ukubonakaliswa komphezulu we-substrate, inika ukuhanjiswa okuphezulu kunye nokufunxa okuncinci kulo lonke uluhlu lokugquma kwe-AR.Jonga iiGrafu kwiireferensi zakho.
