Zinc Selenide (ZnSe)
Magalasi a Bi-Concave

Magalasi a Bi-concave kapena Double-concave (DCV) amakhala ndi utali wolunjika. Ma lens opatukanawa atha kugwiritsidwa ntchito kupatutsa mtengo wowongoka kuti ukhale wolunjika ndipo amagwiritsidwa ntchito mobwerezabwereza mu chowonjezera chamtundu wa ku Galileya. Amagwiritsidwanso ntchito nthawi zambiri kupatukana kapena kuonjezera kusiyana kwa mtengo wolumikizira. M'mawonekedwe a kuwala, ndizofala kuti ochita kafukufuku asankhe ma optics awo mosamala kotero kuti zosokoneza zomwe zimayambitsidwa ndi ma lens owoneka bwino ndi oyipa atalikirapo pafupifupi kutha. Ena amagwiritsa ntchito magalasi awa awiriawiri kuti awonjezere utali wokhazikika wa lens yotembenuka ngati mandala a meniscus.

Posankha pakati pa mandala a plano-concave ndi di-concave lens, zonse zomwe zimapangitsa kuti kuwala kwa chochitikacho kuphatikizepo, nthawi zambiri kumakhala koyenera kusankha lens ya bi-concave ngati chiŵerengero cha conjugate (mtunda wa chinthu wogawidwa ndi mtunda wa chithunzi) ili pafupi ndi 1. Pamene kukulitsa kofunidwa kuli kochepera 0.2 kapena kupitirira 5, chizolowezi chimakhala kusankha mandala a plano-concave m'malo mwake.

Magalasi a ZnSe ndiwoyenera kwambiri kugwiritsidwa ntchito ndi ma laser amphamvu kwambiri a CO2. Paralight Optics imapereka Magalasi a Zinc Selenide (ZnSe) Bi-Concave kapena Double-Concave (DCV) omwe amapezeka ndi zokutira zamtundu wa Broadband AR zokongoletsedwa ndi mawonekedwe a 8 - 12 μm oyikidwa pamalo onse awiri. Kupaka uku kumachepetsa kwambiri kuwunikira kwapamwamba kwa gawo lapansi, kumapereka kufalikira kwapakati pa 97% pamitundu yonse ya zokutira za AR. Kuti mumve zambiri za zokutira, chonde onani ma Grafu otsatirawa pazowunikira zanu.
