Wehewehe Pōkole:

ʻO nā aniani SiC (nā aniani optical silicon carbide) he mau ʻāpana optical pololei i hana ʻia mai ka silicon carbide maʻemaʻe kiʻekiʻe (SiC), e hāʻawi ana i nā waiwai physicochemical kūikawā a me ka hana optical. Hōʻike ʻia e ka conductivity thermal ultrahigh (490 W/m·K), ka coefficient haʻahaʻa o ka hoʻonui thermal (4.0 × 10⁻⁶/K), a me ke kūpaʻa kaiapuni koʻikoʻi, ua lilo nā aniani SiC i koho kūpono loa no nā ʻōnaehana optical e hana ana i nā kūlana koʻikoʻi. Hōʻike kēia mau aniani i ka hana hoʻoili maikaʻi loa (uncoated transmittance >70%) ma waena o nā nalu ultraviolet a i nā nalu infrared mamao (0.2-6 μm), e kūpono loa ana no nā ʻōnaehana laser mana kiʻekiʻe, nā optics ākea, a me ke kiʻi optical i nā ʻano ʻoihana ʻino.

ʻO ke kaʻina hana hana o nā aniani SiC e pili ana i ka wili pololei, ka poli ʻana i ka pololei loa, a me nā hana uhi kūikawā e hoʻokō ai i nā ʻili optical me ka pololei nanoscale (ka ʻoʻoleʻa o ka ʻili <1 nm). Hiki ke hana ʻia nā geometries maʻamau e pili ana i nā ʻili aspheric a me nā ʻili freeform e hoʻokō i nā koi hoʻolālā o nā ʻōnaehana optical kiʻekiʻe.
