Zinc Selenide (ZnSe)
Plano-Convex Lenses

Plano-convex (PCX) lenzi ma lenzi akanaka ayo ari mukobvu mukati kupfuura ari kumucheto, kana mwaranzi yakasanganiswa ichipinda mavari, mwenje unochinjika kuenda kunzvimbo yepanyama.Plano-convex lenses ane rimwe divi rakati sandara uye rimwe divi rakakombama rine radius yakanaka yekukona.Malenzi ePlano-Convex ane hurefu hwekutarisa uye nzira yakanakisa yeasingaperi uye ane magumo conjugate application.Malenzi aya anotarisisa danda rakakomberedzwa kumberi kwekutarisa uye kudhumhana mwenje kubva kunobva nzvimbo.Iwo akagadzirwa ane kushoma spherical aberration uye ane kureba kwakapihwa ne:
f= R/(n-1),
uko R iri radius yekukombama kwechikamu che convex chelenzi uye n indekisi yekuramba.

Plano-convex lenses inoburitsa kushomeka kudiki kana yakatarisa kune infinity (apo chinhu chemufananidzo chiri kure uye conjugate ratio yakakwira).Naizvozvo ndiwo ekuenda-ku-lens mumakamera uye teresikopu.Kunyanya kushanda zvakanaka kunowanikwa kana plano yakatarisana nendege inodiwa, nemamwe mazwi, nzvimbo yakakomberedzwa yakatarisana nebango rechiitiko chakakanganiswa.Plano convex lenzi isarudzo yakanaka yekubatanidza mwenje kana yekutarisa maapplication uchishandisa monochromatic mwenje, mumaindasitiri akadai semaindasitiri, emishonga, marobhoti, kana kudzivirira.Iwo isarudzo yehupfumi yekuda maapplication nekuti ari nyore kugadzira.Sekutonga kwechigunwe, plano-convex lenses inoita zvakanaka kana chinhu nemufananidzo zviri paabsolute conjugate ratios> 5:1 kana <1:5, saka spherical aberration, coma uye kukanganisa zvinoderedzwa.Kana iyo mhedziso inodiwa kukudza iri pakati pezvinhu zviviri izvi, Bi-convex lenzi anowanzo akakodzera.

ZnSe lenzi dzinowanzo shandiswa muI IR imaging, biomedical, uye mauto maapplication, akanyatsokodzera kushandiswa nepamusoro-simba CO2 lasers nekuda kwekuderera kunyura coefficient.Mukuwedzera, vanogona kupa hutachiwana hwakakwana munharaunda inooneka kuti ibvumire kushandiswa kwedanda rekugadzirisa tsvuku.Paralight Optics inopa Zinc Selenide (ZnSe) Plano-Convex (PCV) Lenses inowanikwa nebroadband AR coating yakagadziridzwa 2 µm - 13 μm kana 4.5 - 7.5 μm kana 8 - 12 μm spectral renji yakaiswa pamativi ese ari maviri.Kupfeka uku kunoderedza zvakanyanya avhareji yekuratidzira kweiyo substrate isingasviki 3.5%, ichipa avhareji kutapurirana inodarika 92% kana 97% mukati mese AR coating renji.Tarisai maGrafu anotevera kune mareferensi ako.
