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 chisingaperi 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 inowanika nebroadband AR coating yakagadziridzwa 2 µm - 13 μm kana 4.5 - 7.5 μm kana 8 - 12 μm spectral range yakaiswa panzvimbo dzose dziri mbiri.Uku kupfekedza kunoderedza zvakanyanya kutaridzika kwepamusoro kweiyo substrate, ichipa avhareji yekutapurirana inodarika 92% kana 97% pairi rese AR coating renji.Tarisa maGrafu kune mareferensi ako.
