Ilensi ye-Silicon yaseShayina (ilensi ye-Si) yokwenziwa kwezicelo ze-Infrared kanye neFektri

Ilensi ye-Silicon (ilensi ye-Si) yezinhlelo zokusebenza ze-Infrared

Ubude be-infraredIhlinzeka ngelensi ye-silicon ngobukhulu obudumile obusukela ku-10mm kuya ku-200 mm ububanzi. Usayizi ngelensi ongaphezu kuka-200mm unganikezwa futhi uma ucela. Isembozo sethu esijwayelekile se-AR ne-DLC silungele kakhulu ibhendi engu-3-5 micron. Ubude obuqondile bamalensi ethu buzolawulwa bufike ku-+/-1% ukubekezelelana, ukuthamba komphezulu okungu-λ/4 @ 632.8nm kanye nokungajwayelekile komphezulu okungaphansi kuka-0.5 micron.

Amathegi Omkhiqizo

Ulwazi lomkhiqizo:

Ilensi ye-silicon ilensi yokukhanya eyenziwe nge-silicon. I-Silicon (Si) iyinto ekristalu evame ukusetshenziswa ezinhlelweni zokukhanya ze-infrared ezisebenza ku-spectral band engu-3 kuya ku-5µm. Inkomba yayo yokukhanya iseduze no-3.4 kulo lonke ububanzi. Inobuningi obuphansi phakathi kwezinto ezivamile ze-infrared, okuyingxenye nje ye-Ge, GaAs kanye ne-ZnSe. Ngakho-ke izinto ze-silicon ziyindlela efanelekile yesistimu enenkinga yesisindo. I-Silicon nayo iqinile futhi ishibhile kunezinye izinto ezivamile ze-infrared, inciphisa izindleko zezinto ngenkathi ikhulisa izindleko zokukhiqiza ngesikhathi esifanayo.

I-silicon ifaneleka kahle ukusetshenziswa kwe-MWIR kodwa ngenxa yokumuncwa kwayo okunamandla ngaphezu kwama-micron ayi-6, ayifanele ukusetshenziswa kwe-LWIR. Ingasetshenziswa futhi njengesibuko sokusetshenziswa kwe-laser ngenxa yokushisa kwayo, isisindo sayo esincane, kanye nobunzima.

I-Wavelength Infraredingakha uhlobo oluhlukahlukene lwelensi ye-silicon ngeizindawo ezibanzi, ezigobile, ezijiyile, ezingenalutho kanye nezisakazekayo.I-Silicon ithandwa kakhulu ezinhlelweni ezisebenza esifundeni se-spectral esingu-3-5µm, ezinezimbozo ezivimbela ukukhanya (i-AR coating), ukudluliselwa okujwayelekile kungakhushulwa kufike ku-98%. Singafaka futhi imbozo efana ne-carbon (i-DLC coating) noma imbozo eqinile (i-HD coating) ebusweni belensi ukuze sinikeze isivikelo esengeziwe ekuklwebhekeni nasekushayweni.

Ubude be-infraredikhiqiza ilensi ye-silicon eyindilinga ne-aspheric esezingeni eliphezulu. Ingagxila noma ihlukanise ukukhanya okungenayo ukuze ihlangabezane nezidingo ezithile zesistimu ye-infrared.
