Zinc Selenide (ZnSe)
Bi-Convex Lenses

Bi-Convex kana Double-Convex (DCX) Spherical Lenzis ane denderedzwa uye ane yakafanana curvature pamativi ese maviri elenzi, saka ane symmetric uye ane yakanaka focal kureba. Payuniti conjugation, coma uye kukanganisa kunodzima nekuda kwekuenzanirana. Aya malenzi anogona kushandiswa kutarisa mwenje unouya uye anozivikanwa kune akawanda ekupedzisira ekufungidzira maapplication.

Kunyangwe maBi-convex lenzi achideredza kutsauka mumamiriro ezvinhu apo chinhu nemufananidzo zvinhambwe zvakaenzana kana kuda kuenzana, kana uchifunga pakati pebi-convex kana DCX lens uye plano-convex lens, izvo zvese zvinokonzeresa kuti collimated chiitiko chiedza chisanganise. kazhinji zviri nani kusarudza bi-convex lenzi yekuderedza kutsauka kana reshiyo yechinhu nemifananidzo madaro (absolute conjugate ratio) iri pakati pe5:1 ne1:5. Kunze kwemhando iyi, plano-convex lenses inowanzofarirwa.

ZnSe lenzi dzakanyanya kukodzera kushandiswa nepamusoro-simba CO2 lasers. Paralight Optics inopa Zinc Selenide (ZnSe) Bi-Convex Lenses inowanika nebroadband AR coating yakagadziridzwa 8 kusvika 12 μm spectral renji yakaiswa pane ese ari maviri. Uku kupfekedza kunoderedza zvakanyanya kutarisisa kwepamusoro kweiyo substrate, ichipa avhareji yekufambisa inopfuura 97% pamusoro peiyo AR coating renji. Tarisai maGrafu anotevera kune mareferensi ako.
