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 anowanzodiwa.
Nekuda kwehupamhi hwekutapurirana renji (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) Lenses inowanika nebroadband AR coating ye8 µm kusvika 12 μm spectral renji yakaiswa panzvimbo mbiri. Uku kupfekedza kunoderedza zvakanyanya kutarisisa kwepamusoro kweiyo substrate, ichipa avhareji yekufambisa inopfuura 97% pamusoro peiyo AR coating renji. Tarisa maGrafu kune mareferensi ako.
