Plano-Convex Lenses
Pakusarudza pakati pe plano-convex lens uye bi-convex lens, izvo zvese zvinokonzeresa kuti collimated chiitiko chiedza chishanduke, kazhinji zviri nani kusarudza plano-convex lens kana iyo inodiwa magnification iri pasi pe0.2 kana kupfuura 5 kana kupfuura 5 Pakati pezvinhu zviviri izvi, ma-bi-convex lenzi anonyanyodiwa.
Nekuda kwehupamhi hwekutapurirana huwandu (2 - 16 µm) uye yakagadzikana makemikari zvivakwa, Germanyium inonyatso kukodzera kune IR laser application, yakanakira kuchengetedza, mauto uye ekufungidzira maapplication.Zvisinei Ge's transmission properties inonyatsonzwa tembiricha;kutaura zvazviri, kunyura kunova kwakakura zvekuti germanium inoita kunge isina kujeka pa100 °C uye isingatapurire zvachose pa200 °C.
Paralight Optics inopa Germanium (Ge) Plano-convex (PCX) Malenzi anowanikwa aine Broadband AR coating ye8 µm kusvika 12 μm spectral renji yakaiswa panzvimbo dzese dziri mbiri.Uku kupfekedza kunoderedza zvakanyanya kutaridzika kwepamusoro kweiyo substrate, ichipa avhareji yekutapurirana inodarika 97% pamusoro peiyo AR coating renji.Tarisa maGrafu kune mareferensi ako.
