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.

Iisampulu zezicelo Izicelo ze-OEM

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 ukukhulisa ngokupheleleyo okufunekayo kungaphantsi kwe-0.2 okanye kukhulu 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.
