MgF2 ka lepo
wehewehe
Hoʻohana ʻia ʻo MgF2 ma ke ʻano he lens, prism a me ka puka makani no ka lōʻihi hawewe mai 110nm a 7.5μm.He mea kūpono loa ia e like me ka puka makani no ArF Excimer Laser, no ke kumu o kona hoʻouna maikaʻi ʻana ma 193nm.He mea maikaʻi hoʻi e like me ka polarizing optical i ka ʻāpana ultraviolet.

ʻO ka wehewehe ʻana o ka substrate MgF2
ʻO ka pāpaʻi MgF2 e pili ana i kahi pani i hana ʻia me ka mea aniani o ka magnesium fluoride (MgF2).ʻO ka MgF2 he mea hoʻoheheʻe inorganic i haku ʻia me nā mea magnesium (Mg) a me ka fluorine (F).
Loaʻa i nā substrates MgF2 kekahi mau waiwai kaulana e kaulana ai lākou i nā ʻano noi like ʻole, ʻoi aku hoʻi ma nā ʻano optics a me ka deposition kiʻiʻoniʻoni lahilahi.
1. Mākaʻikaʻi kiʻekiʻe: Loaʻa i ka MgF2 ke aniani maikaʻi loa i nā ʻāpana ultraviolet (UV), ʻike ʻia a infrared (IR) o ka spectrum electromagnetic.Loaʻa iā ia kahi ākea ākea mai ultraviolet ma kahi o 115 nm a i infrared ma kahi o 7,500 nm.
2. Ka helu haʻahaʻa o ka refraction: MgF2 he haʻahaʻa haʻahaʻa o ka refraction, e lilo ia i mea kūpono no nā uhi AR a me nā optics, no ka mea, e hōʻemi ana i nā noʻonoʻo makemake ʻole a hoʻomaikaʻi i ka lawe māmā.
3. Haʻahaʻa haʻahaʻa: MgF2 hōʻike haʻahaʻa absorption i ka ultraviolet a me nā ʻāpana spectral ʻike ʻia.Hoʻohana kēia waiwai i ka pono i nā noi e koi ana i ka mālamalama optical kiʻekiʻe, e like me nā lens, prisms, a me nā puka makani no ka ultraviolet a i ʻole nā kukui ʻike ʻia.
4. Paʻa kemika: ʻO ka MgF2 he mea paʻa kemika, kūpaʻa i ka nui o nā mea kemika, a mālama i kāna mau hiʻohiʻona optical a me ke kino ma lalo o kahi ākea ākea.
5. Thermal paʻa: MgF2 he kiʻekiʻe heheʻe wahi a hiki ke pale aku kiʻekiʻe hana wela me ka nui degradation.
Hoʻohana maʻamau ʻia nā substrate MgF2 i loko o nā uhi ʻili, nā kaʻina hana hoʻoheheʻe kiʻiʻoniʻoni lahilahi, a me nā puka aniani a i ʻole nā lens i nā mea like ʻole a me nā ʻōnaehana.Hiki iā lākou ke lawelawe ma ke ʻano he papa pale a i ʻole nā mea hoʻohālike no ka ulu ʻana o nā kiʻi ʻoniʻoni ʻoniʻoni ʻē aʻe, e like me nā mea semiconductor a i ʻole nā mea metala.
Hoʻohana pinepine ʻia kēia mau substrate me ka hoʻohana ʻana i nā ʻenehana e like me ka waiho ʻana o ka mahu a i ʻole ke ʻano o ka lawe ʻana i ka mahu kino, kahi i waiho ʻia ai nā mea MgF2 ma kahi mea substrate kūpono a i ulu ʻia e like me ke aniani hoʻokahi.Ma muli o nā koi noi, hiki i nā substrates ke ʻano o nā wafers, nā papa, a i ʻole nā ʻano maʻamau.
