Zinc Selenide (ZnSe)
Magalasi a Plano-Concave

Magalasi a plano-concave ndi ma lens oyipa omwe amakhala okulirapo m'mphepete kuposa apakati, kuwala kumadutsa pakati pawo, kumasiyana ndipo malo omwe amawunikira amakhala pafupifupi.Kutalika kwawo ndi koyipa, komanso utali wopindika wa malo opindika.Potengera kupindika kwawo kozungulira koyipa, magalasi a plano-concave atha kugwiritsidwa ntchito kuti azitha kusuntha mozungulira chifukwa cha magalasi ena panjira yowonera.Magalasi a plano-concave ndi othandiza pakupatutsa mtengo wopindika ndikuphatikiza mtengo wopindika, amagwiritsidwa ntchito kukulitsa nyali zowala ndikuwonjezera utali wokhazikika pamakina omwe alipo.Magalasi oyipawa amagwiritsidwa ntchito kwambiri mu telescopes, makamera, ma lasers kapena magalasi kuti athandizire makina okulitsa kukhala ophatikizika.

Magalasi a plano-concave amachita bwino ngati chinthu ndi chithunzicho zili pamiyezo yolumikizana, yoposa 5:1 kapena kuchepera 1:5.Pachifukwa ichi, ndizotheka kuchepetsa kuphulika kwa spherical, coma, ndi kupotoza.Mofananamo ndi magalasi a plano-convex, kuti akwaniritse bwino kwambiri malo opindika ayenera kuyang'anizana ndi mtunda waukulu kwambiri wa chinthu kapena cholumikizira chopanda malire kuti achepetse kufalikira kwa spherical (kupatula ngati agwiritsidwa ntchito ndi ma laser amphamvu kwambiri pomwe izi ziyenera kusinthidwa kuti zithetse kuthekera kwa pafupifupi. kuganizira).

Magalasi a ZnSe ndi oyenera kugwiritsidwa ntchito ndi ma laser amphamvu kwambiri a CO kapena CO2.Kuonjezera apo, angapereke kufalitsa kokwanira m'dera lowoneka kuti alole kugwiritsira ntchito mtengo wowonekera wolunjika, ngakhale kuti zowonetsera kumbuyo zikhoza kumveka bwino.Paralight Optics imapereka Magalasi a Zinc Selenide (ZnSe) Plano-Concave (PCV) omwe amapezeka ndi zokutira za burodibandi za AR zokongoletsedwa ndi 2 µm - 13 μm kapena 4.5 - 7.5 μm kapena 8 - 12 μm zowoneka bwino zoyikidwa pamalo onse awiri.Kupaka uku kumachepetsa kwambiri kuwunikira kwapamwamba kwa gawo lapansi, kumapereka kufalikira kwapakati pa 92% kapena 97% pamitundu yonse ya zokutira za AR.Yang'anani ma Grafu kuti mupeze zolozera zanu.
