Germanium optics-Ge arotahi

Whakaahuatanga Poto:

Ko nga arotahi Germanium he arotahi whatu i hangaia mai i te germanium kua orohia.Ko enei arotahi he pakari, he atete ki te pirau, he pai hoki mo nga taiao kino me nga tono kei reira nga waahi e mau tonu ana ki nga huānga.

Whakaahuatanga Hua

Ko te karaihe kotahi o germanium e whakamahia ana i roto i te semiconductor he iti ake te whakauru i roto i te roangaru infrared o 2 - 20μm ka taea te whakamahi hei huānga whatu o te rama infrared.He arotahi kotahi i mahia ki te karaihe germanium.Ka whakamahia hei arotahi o te kaamera ki te mataki i te infrared, penei i te thermography.

Ahakoa te ahua o te marama kaore i te tuku na te mea ko tona kanapa whakarewa, kei te tuku i roto i te whanui infrared awhe o 2 - 20μm. Ko te roangaru o te 1.5μm iti iho ranei e kore e tuku, na reira e whakarato ana hoki i te painga o te whakawhitinga infrared. tātari.I te mea he 4 neke atu ranei te taupū o te mata kirikiri, he puhoi ake te kopiko o te arotahi ka mahia mai i te karaehe paerewa.

Ka taea e te arotahi Germanium te whiti whakarewa, kia whakaatahia te marama ka kitea.Na tenei, karekau he whakawhitinga.Ko te arotahi Tiamana kaore he paninga anti-whakaata kua ngaro na te whakaata o te mata me te hua o te whakawhiti mo te 40%.Mo te tirohanga o nga roangaru infrared, he mea tika ki te whakaaro ki te paanga o te rererangi iraruke. mā te pāmahana.Mena ka whakamahia i roto i te taiao 30 ℃ neke atu ranei, ka puta te marama o te infrared (tata ki te 9.6μm) mai i nga matū katoa, a ka kore e taea e ia te mataki tika i tenei hiranga infrared.

Āhuahira

1. Kei te watea katoa nga arotahi plan-concave, p-convex, concave-convex me aspheric.

2. Kei te waatea me te paninga AR, DLC ranei

3. E waatea ana i roto i nga momo whanui me te roa o te arotahi

4. High resistivity hemispherical arotahi e wātea ana

Taupānga

Na o ratou ahuatanga whakamiharo, ka whakamahia nga arotahi germanium ki nga arotahi kamera mo te inenga wera infrared, He pai mo te Tiaki, Haumarutanga, me nga Tono Ataahua Ngawha.
