Zinc Selenide (ZnSe)
Plano-Concave Lenses
Plano-concave lenzi anoita zvakanaka kana chinhu nemufananidzo zviri paabsolute conjugate ratios, yakakura kupfuura 5:1 kana isingasviki 1:5. Muchiitiko ichi, zvinokwanisika kuderedza spherical aberration, coma, uye kukanganisa. Saizvozvo ne plano-convex lenses, kuti ibudirire zvakanyanya nzvimbo yakakomberedzwa inofanirwa kutarisana nechinhu chikuru chinhambwe kana iyo isingaperi conjugate kudzikisa spherical aberration (kunze kwekunge ichishandiswa neakakwira-energy lasers apo izvi zvinofanirwa kudzoserwa kubvisa mukana weiyo chaiyo. focus).
ZnSe lenzi dzakanyanya kukodzera kushandiswa nepamusoro-simba CO kana CO2 lasers. Mukuwedzera, vanogona kupa hutachiwana hwakakwana munharaunda inooneka kubvumira kushandiswa kwechigadziko chinooneka chekugadzirisa, kunyange zvazvo zviratidzo zvemashure zvingave zvakanyanya kutaurwa. Paralight Optics inopa Zinc Selenide (ZnSe) Plano-Concave (PCV) Lenses inowanikwa nebroadband AR coating yakagadziridzwa 2 µm - 13 μm kana 4.5 - 7.5 μm kana 8 - 12 μm spectral renji yakaiswa pamativi ese ari maviri. Uku kupfekedza kunoderedza zvakanyanya kutaridzika kwepamusoro kweiyo substrate, ichipa avhareji yekutapurirana inodarika 92% kana 97% pairi rese AR coating renji.
