Zinc Selenide (ZnSe)
Nā Lens Plano-Convex

ʻO nā lens Plano-convex (PCX) nā lens maikaʻi i ʻoi aku ka mānoanoa o ka waena ma mua o ka lihi, ke hele nā kukuna collimated ma o lākou, huli ka mālamalama i kahi kiko kino.Hoʻokahi ʻaoʻao pālahalaha a hoʻokahi ʻaoʻao ʻōwili me ka radius kūpono o ka curvature.Loaʻa i nā lens Plano-Convex ka lōʻihi kikoʻī kūpono a hoʻokokoke i ke ʻano maikaʻi loa no nā noi conjugate palena ʻole a pau.Hoʻopili kēia mau lens i kahi kukui i hoʻopili ʻia i ke kua a hoʻopili i ke kukui mai kahi kumu kiko.Hoʻolālā ʻia lākou me ka liʻiliʻi o ka spherical aberration a loaʻa ka lōʻihi kikoʻī i hāʻawi ʻia e:
f= R/(n-1),
ma kahi o R ka radius o ka curvature o ka mahele convex o ka lens a o n ka index of refraction.

Hāʻawi nā lens plano-convex i ka distortion spherical liʻiliʻi i ka wā e kālele ana i ka palena ʻole (ke mamao ka mea i kiʻi ʻia a kiʻekiʻe ka ratio conjugate).No laila ʻo lākou ka lens hele i nā kāmera a me nā telescopes.Loaʻa ka hana kiʻekiʻe loa i ka wā e kū ai ka ʻili plano i ka mokulele kiko i makemake ʻia, ʻo ia hoʻi, ʻo ka ʻili curved e kū pono ana i ke kukui hanana collimated.ʻO nā lens convex Plano kahi koho maikaʻi no ka collimation māmā a i ʻole no ka nānā ʻana i nā noi e hoʻohana ana i ka hoʻomālamalama monochromatic, i nā ʻoihana e like me ka ʻoihana, lāʻau lapaʻau, robotics, a i ʻole pale.He koho waiwai lākou no ka koi ʻana i nā noi no ka mea maʻalahi lākou e hana.E like me ke kānāwai o ka manamana nui, hana maikaʻi nā lens plano-convex ke loaʻa ka mea a me ke kiʻi i nā ratio conjugate piha > 5:1 a i ʻole <1:5, no laila e hoʻemi ʻia ka spherical aberration, coma a me ka distortion.Aia ka hoʻonui piha i makemake ʻia ma waena o kēia mau waiwai ʻelua, ʻoi aku ka maikaʻi o nā lens Bi-convex.

Hoʻohana pinepine ʻia nā lens ZnSe i ka IR imaging, biomedical, a me nā noi koa, ua kūpono lākou no ka hoʻohana ʻana me nā lasers CO2 mana kiʻekiʻe ma muli o ka haʻahaʻa absorption coefficient.Eia hou, hiki iā lākou ke hāʻawi i ka hoʻouna ʻana ma ka ʻāpana ʻike ʻia e ʻae i ka hoʻohana ʻana i kahi kukui alignment ʻulaʻula.Hāʻawi ʻo Paralight Optics iā Zinc Selenide (ZnSe) Plano-Convex (PCV) Lenses i loaʻa me kahi uhi AR broadband i hoʻopaʻa ʻia no ka 2 µm - 13 μm a i ʻole 4.5 - 7.5 μm a i ʻole 8 - 12 μm spectral range i waiho ʻia ma nā ʻaoʻao ʻelua.Hoʻemi nui kēia uhi i ka awelika o ka nānā ʻana o ka substrate ma lalo o 3.5%, e hāʻawi ana i ka hoʻoili awelika i ʻoi aku ma mua o 92% a i ʻole 97% ma waena o ka laulā uhi AR āpau.E nānā i nā kiʻi ma lalo no kāu mau kuhikuhi.
