Lens Silicon (Si lens) no nā noi Infrared

ʻO ka lens silikon he lens optical i hana ʻia me ke silika.ʻO Silicon (Si) kahi mea crystalline i hoʻohana mau ʻia i nā ʻōnaehana optical infrared e hana ana ma ka 3 a 5µm spectral band.Kokoke kona index refractive i ka 3.4 a puni ka laula.He haʻahaʻa haʻahaʻa kona ma waena o nā mea infrared maʻamau, ʻo ia ka hapalua o Ge, GaAs a me ZnSe.No laila ʻo ka mea silika kahi koho kūpono no ka ʻōnaehana me ka hopohopo kaumaha.ʻOi aku ka paʻakikī a ʻoi aku ka maikaʻi o ka silikoni ma mua o ka hapa nui o nā mea infrared maʻamau, e hoʻemi i ke kumukūʻai waiwai a hoʻonui i ke kumukūʻai hana i ka manawa like.

Ua kūpono ʻo Silicon no ka noi MWIR akā ma muli o ka ikaika o ka absorption ma luna o 6 micron, ʻaʻole kūpono ia no ka noi LWIR.Hiki ke hoʻohana ʻia ma ke ʻano he aniani substrate no ka noi laser ma muli o kāna conductivity thermal, ke kaumaha māmā, a me ka paʻakikī.

Infrared lōʻihi hawewehiki ke hana i nā ʻano ʻano lens silika memokulele, concave, convex, aspheric and diffractive surfaces.ʻO ka silikoni ka mea kaulana loa no nā ʻōnaehana e hana ana ma ka ʻāpana spectral 3-5µm, me nā uhi anti-reflective (AR coating), hiki ke lawe ʻia i ka 98%.Hiki iā mākou ke hoʻopili i ka uhi kalapona e like me daimana (DLC coating) a i ʻole ka uhi paʻa kiʻekiʻe (HD coating) ma ka ʻili o ka lens e hāʻawi i ka pale hou aku i ka ʻōpala a me ka hopena.

Infrared lōʻihi hawewehana ʻo ia i ka lens spherical maʻamau a me aspheric silika.Hiki iā lākou ke nānā a hoʻokaʻawale paha i ke kukui uila e hoʻokō i nā koi kikoʻī o ka ʻōnaehana infrared.
