Zinc Selenide
Muraayadaha Meniscus ee taban

Muraayadaha 'Meniscus lenses' ayaa ugu horrayn loo isticmaalaa in diiradda lagu saaro cabbirrada dhibcaha yar yar ama codsiyada isku-dhafka. Waxay bixiyaan waxqabad aad u sarreeya iyagoo si weyn u yareynaya aberrations wareega. lenses taban (convex-concave) lenses , kuwaas oo ka kooban dusha convex iyo dusha concave ah oo ka khafiifsan dhexda marka loo eego cidhifyada & sababa falaadhaha iftiinka in ay kala duwanaadaan, waxaa loogu talagalay in la yareeyo aberration spherical ee hababka indhaha.

Marka loo isticmaalo in lagu kala saaro iftiinka codsiyada balaadhinta alwaaxdu, dusha sare ee concave waa in ay wajahdo laydhka si loo yareeyo khalkhalka wareega. Marka lagu daro lens kale, lenska meniscus taban wuxuu kordhin doonaa dhererka focal wuxuuna hoos u dhigayaa daloolka nambarada (NA) ee nidaamka.

Muraayadaha ZnSe waxay ku habboon yihiin codsiga CO2 lasers sababtoo ah sifooyinka sawir-qaadista ee heer sare ah iyo caabbinta sare ee shoogga kuleylka. Paralight Optics waxay bixisaa Zinc Selenide (ZnSe) lenses meniscus taban, muraayadahani waxay yareeyaan NA ee nidaamka indhaha waxaana lagu heli karaa daahan ballaadhan oo ka-hortagga milicsiga, kaas oo loogu wanagsan yahay 8 µm ilaa 12 μm kala duwanaansho muuqaal ah oo lagu kaydiyo labadaba dusha iyo waxsoosaarka. celceliska gudbinta in ka badan 97% in ka badan kala duwan ee daahan AR oo dhan.
