IiLensi zePlano-Convex
Xa uthatha isigqibo phakathi kwelensi yeplano-convex kunye ne-bi-convex lens, zombini ezibangela ukuba ukukhanya kwesiganeko esidityanisiweyo kuhlangane, kudla ngokukhetheka ukukhetha iplano-convex lens ukuba ulwandiso olufunekayo lungaphantsi kwe-0.2 okanye lukhulu kuno-5 Phakathi kwala maxabiso mabini, iilensi ze-bi-convex zikhethwa ngokubanzi.
Ngenxa yoluhlu olubanzi lothumelo ( 2 – 16 µm) kunye neepropati zekhemikhali ezizinzile, i-Germanium ifanelekele usetyenziso lwelaser ye-IR, igqwesile kukhuseleko, usetyenziso lomkhosi kunye ne-imaging. Nangona kunjalo iipropathi zothumelo lwe-Ge zinovakalelo oluphezulu lobushushu; eneneni, ukufunxwa kuba kukhulu kangangokuba igermanium iphantse ibe yi-opaque kwi-100 °C kwaye ayidluliseli ngokupheleleyo kwi-200 °C.
IParalight Optics ibonelela ngeGermanium (Ge) iPlano-convex (PCX) iiLensi ezifumaneka ngebroadband AR yokwambathisa kwi-8 µm ukuya kwi-12 μm yoluhlu lokubonwayo olufakwe kuyo yomibini imiphezulu. Olu gquba lunciphisa kakhulu ukubonakala okuphezulu komphezulu we-substrate, inika usasazo oluyi-avareji ngaphezulu kwe-97% kulo lonke uluhlu lwe-AR yokwambathisa. Jonga iiGrafu kwiireferensi zakho.
