Zinc Selenide (ZnSe)
Magalasi a Bi-Convex

Magalasi a Bi-Convex kapena Double-Convex (DCX) ndi ozungulira ndipo ali ndi kupindika kofanana mbali zonse za mandala, motero amakhala ofananira ndipo amakhala ndi utali wolunjika. Pakulumikizana kwa unit, chikomokere ndi kupotoza zimasiya chifukwa chakufanana. Magalasi awa atha kugwiritsidwa ntchito kuyang'ana kuwala komwe kukubwera ndipo ndi otchuka pazithunzi zambiri zopanda malire.

Ngakhale magalasi a Bi-convex amachepetsa kusinthika pakachitika zinthu zomwe mtunda wa chinthu ndi chithunzi ndi wofanana kapena pafupifupi wofanana, posankha pakati pa bi-convex kapena DCX lens ndi plano-convex lens, zonse zomwe zimapangitsa kuti kuwala kwa zochitika kuphatikizike. nthawi zambiri ndi bwino kusankha mandala awiri-convex kuti achepetse kutembenuka ngati chiŵerengero cha chinthu ndi mtunda wa chithunzi (chiwerengero cha conjugate) chili pakati pa 5: 1 ndi 1: 5. Kunja kwamtunduwu, magalasi a plano-convex nthawi zambiri amakonda.

Magalasi a ZnSe ndiwoyenera kwambiri kugwiritsidwa ntchito ndi ma laser amphamvu kwambiri a CO2. Paralight Optics imapereka Magalasi a Zinc Selenide (ZnSe) Bi-Convex omwe amapezeka ndi zokutira zamtundu wa Broadband AR zokongoletsedwa ndi mawonekedwe a 8 mpaka 12 μm omwe amayikidwa pamalo onse awiri. Kupaka uku kumachepetsa kwambiri kuwunikira kwapamwamba kwa gawo lapansi, kumapereka kufalikira kwapakati pa 97% pamitundu yonse ya zokutira za AR. Yang'anani m'ma Grafu otsatirawa kuti mupeze zolozera zanu.
