Lens Germanium (Ge lens) maka ngwa infrared

Lens Germanium bụ oghere anya nke germanium mere.Germanium (Ge) bụ ihe kristal nwere ntụzịaka kacha elu (4.002@11µm) nke ihe infrared a na-ejikarị.Ọ na-enwekwa mgbasasa dị ala, nnukwu ike ike na njupụta.N'ihi oke mgbasa ozi ya sara mbara (ihe karịrị 45% na band 2-12 micron) na opaque na UV na ìhè a na-ahụ anya, Germanium dabara nke ọma maka ngwa IR dị ka sistemụ onyonyo thermal, ngwa ubi infrared na ngwa nyocha nkenke.

Germanium na-anọkwa n'okpuru mgbapụ ọkụ.Na okpomọkụ na-eto eto, absorption na-abawanye ngwa ngwa.N'ihi mmetụta a na-ekpo ọkụ na-agba ọsọ, oghere germanium adịghị mma ka ejiri ya mee ihe na okpomọkụ karịa 100 ° C.

Infrared wavelength nwere ike iji ụgbọ elu, concave, convex, aspheric na diffractive arụpụta ụdị dị iche iche nke oghere germanium.Germanium kacha ewu ewu maka sistemu na-arụ ọrụ na mpaghara 3-5 ma ọ bụ 8-12µm, yana mkpuchi mgbochi na-egosipụta ( mkpuchi AR), nkezi nnyefe nwere ike bute ruo 97.5-98.5% dabere na bandwit nke mkpuchi.Anyị nwekwara ike tinye diamond dị ka carbon mkpuchi (DLC mkpuchi) ma ọ bụ elu inogide mkpuchi (HD mkpuchi) n'elu oghere iji nyekwuo nchebe megide ọkọ na mmetụta.

Infrared wavelength na-arụpụta ezigbo okirikiri okirikiri na oghere germanium aspheric.Ha nwere ike ilekwasị anya ma ọ bụ gbanwee ọkụ ọkụ na-abata iji mezuo ihe achọrọ maka sistemụ infrared.Ngwa ahụ nwere ike ịbụ foto thermal, thermograph, beam collimating, spectrum analysis na wdg.
