Silicon Lens (Si lens) maka ngwa infrared

Igwe anya silicon bụ oghere anya nke ejiri silicon mee.Silicon (Si) bụ ihe kristal nke a na-ejikarị na sistemu anya infrared na-arụ ọrụ na band spectral 3 ruo 5µm.Ndekọ ntugharị ya dị nso 3.4 n'ogologo.O nwere njupụta dị ala n'etiti ihe infrared nkịtị, nke bụ naanị ọkara nke Ge, GaAs na ZnSe.Ya mere, ihe silicon bụ ezigbo nhọrọ maka sistemụ nwere nchegbu ibu.Silicon dịkwa ike ma dị ọnụ ala karịa ọtụtụ n'ime ihe ndị a na-ahụkarị infrared, belata ọnụ ahịa ihe ma na-abawanye ọnụ ahịa mmepụta n'otu oge.

Silicon dabara nke ọma maka ngwa MWIR mana n'ihi nnabata siri ike karịa 6 micron, ọ dabara na ngwa LWIR.Enwere ike iji ya dị ka mkpụrụ enyo maka ngwa laser n'ihi ịdị ọkụ ya, ịdị arọ ya, na ike siri ike.

Infrared ogologo ogologonwere ike iji mepụta oghere silicon dị iche icheugbo elu, concave, convex, aspheric and diffractive surfaces.Silicon bụ ihe kachasị ewu ewu maka sistemụ na-arụ ọrụ na mpaghara 3-5µm spectral, yana mkpuchi mgbochi na-atụgharị (AR mkpuchi), enwere ike iweta nkezi nnyefe ruo 98%.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 ogologo ogologona-arụpụta àgwà omenala okirikiri na oghere silicon aspheric.Ha nwere ike ilekwasị anya ma ọ bụ gbanwee ọkụ ọkụ na-abata iji mezuo ihe achọrọ maka sistemụ infrared.
