I-Zinc Selenide (ZnSe)
Amalensi e-Plano-Concave

Amalensi e-Plano-concave angamalensi anegethivu ajiyile emaphethelweni kunamaphakathi, lapho ukukhanya kudlula kuwo, ayahluka futhi indawo okugxilwe kuyo ingokoqobo.Ubude bazo bokugxila bunegethivu, kanye ne-radius yokugoba kwezindawo ezigobile.Uma kubhekwa ukujika kwawo okuyindilinga okunegethivu, amalensi e-plano-concave angasetshenziswa ukuze kulinganiswe ukuphambuka okuyindilinga okubangelwa amanye amalensi kusistimu yokubona.Amalensi e-Plano-concave awusizo ekuhlukaniseni i-collimated beam kanye nokuhlanganisa i-convergent beam, asetshenziselwa ukwandisa imishayo yokukhanya nokwandisa ubude bokugxila ezinhlelweni ezikhona zokubona.Lawa ma-lens anegethivu avame ukusetshenziswa kuma-telescopes, amakhamera, ama-laser noma ezingilazini ukuze asize amasistimu okukhulisa ahlangane kakhudlwana.

Amalensi e-Plano-concave asebenza kahle uma into nesithombe kuku-absolute conjugate ratios, okukhulu kuno-5:1 noma ngaphansi kuka-1:5.Kulokhu, kungenzeka ukunciphisa ukuphuma okuyindilinga, i-coma, nokuhlanekezela.Ngokufanayo namalensi e-plano-convex, ukuze kuzuzwe ukusebenza kahle okuphezulu indawo egobile kufanele ibhekane nebanga lento enkulu kunazo zonke noma i-conjugate engapheli ukuze kuncishiswe ukuphuma okuyindilinga (ngaphandle uma isetshenziswa ngamalaser anamandla amakhulu lapho lokhu kufanele kubuyiselwe emuva ukuze kuqedwe ukuba nokwenzeka kwe-virtual aberration. gxila).

Amalensi e-ZnSe afaneleka kakhulu ukusetshenziswa namalaser anamandla e-CO noma e-CO2.Ukwengeza, bangase banikeze ukudluliswa okwanele endaweni ebonakalayo ukuze bavumele ukusetshenziswa kwe-beam yokuqondanisa ebonakalayo, nakuba ukucabangela emuva kungase kubonakale kakhudlwana.I-Paralight Optics inikeza Amalensi e-Zinc Selenide (ZnSe) e-Plano-Concave (PCV) atholakala nge-broadband AR coating elungiselelwe u-2 µm – 13 μm noma 4.5 – 7.5 μm noma 8 – 12 μm ububanzi bokubuka obufakwe kuzo zombili izindawo.Lokhu kunamathela kunciphisa kakhulu ukubukeka okuphezulu kwendawo engaphansi, kunikeze ukudluliswa okumaphakathi okungaphezu kuka-92% noma u-97% kulo lonke uhla lokumboza lwe-AR.Hlola Amagrafu ukuze uthole izinkomba zakho.
