Nā ʻano aniani

Kaaniani mokulele
1.Dielectric coating mirror: Dielectric coating mirror he multi-layer dielectric coating i waiho ʻia ma luna o ka ʻili o ka mea optical, e hoʻopuka ana i ka interference a hoʻonui i ka noʻonoʻo ʻana i kekahi mau hawewe lōʻihi. He kiʻekiʻe ka reflectivity o ka uhi dielectric a hiki ke hoʻohana ʻia i kahi ākea ākea. ʻAʻole lākou e komo i ka māmā a ʻano paʻakikī, no laila ʻaʻole hiki ke pohō. He kūpono lākou no nā ʻōnaehana optical e hoʻohana ana i nā lasers multi-wavelength. Eia nō naʻe, ʻo kēia ʻano aniani he papa kiʻiʻoniʻoni mānoanoa, pili i ke kihi o ka hopena, a he kumu kūʻai kiʻekiʻe.

2.Laser Rays Mirror: ʻO ka mea kumu o ka aniani kukuna laser he ultraviolet fused silica, a ʻo ke kiʻi reflectivity kiʻekiʻe ma luna o kona ili ʻo Nd: YAG dielectric film, i waiho ʻia e ka electron beam evaporation a me ke kaʻina deposition kōkua ion. Ke hoʻohālikelike ʻia me nā mea K9, ʻoi aku ka maikaʻi o ka like ʻana o ka silica fused UV a me ka coefficient haʻahaʻa o ka hoʻonui ʻana i ka wela, e kūpono loa ia no nā noi i ka ultraviolet a kokoke i ka laulā nalu infrared, nā lasers mana kiʻekiʻe a me nā kahua kiʻi. ʻO nā lōʻihi hawewe hana maʻamau no nā aniani kukuna laser he 266 nm, 355 nm, 532 nm, a me 1064 nm. Hiki i ke kihi hanana ke 0-45 ° a i ʻole 45 °, a ʻoi aku ka noʻonoʻo ʻana ma mua o 97%.

3.Ultrafast aniani: ʻO ka mea kumu o ke aniani ultrafast he ultraviolet fused silica, a ʻo ke kiʻi kiʻi reflectivity kiʻekiʻe ma luna o kona ʻili he kiʻi ʻoniʻoni dispersion dispersion haʻahaʻa, i hana ʻia e ka ion beam sputtering (IBS). He haʻahaʻa haʻahaʻa ko UV fused silica o ka hoʻonui wela a me ke kūpaʻa haʻalulu kiʻekiʻe, e kūpono ia no nā lasers pulsed femtosecond mana kiʻekiʻe a me nā noi kiʻi. ʻO nā pae hawewe hana maʻamau no nā aniani ultrafast he 460 nm-590 nm, 700 nm-930 nm, 970 nm-1150 nm, a me 1400 nm-1700 nm. ʻO 45 ° ke kukui hanana a ʻoi aku ka hoʻohālikelike ʻana ma mua o 99.5%.

4.Supermirrors: Hana ʻia nā Supermirrors ma ka waiho ʻana i nā ʻāpana ʻokoʻa o nā mea dielectric index refractive kiʻekiʻe a haʻahaʻa ma kahi substrate silica fused UV. Ma ka hoʻonui ʻana i ka helu o nā papa, hiki ke hoʻomaikaʻi ʻia ka reflectivity o ka super-reflector, a ʻoi aku ka reflectivity ma mua o 99.99% i ka nalu o ka hoʻolālā. ʻO kēia ka mea kūpono no nā ʻōnaehana optical e koi ana i ka noʻonoʻo kiʻekiʻe.

5.Metallic Mirrors: He kūpono nā aniani metallic no ka hoʻohuli ʻana i nā kumu kukui broadband, me ka noʻonoʻo kiʻekiʻe ma luna o kahi ākea ākea. Hiki i nā kiʻiʻoniʻoni metala ke hoʻoheheʻe ʻia, ka wehe ʻana a i ʻole ka ʻili ʻana i nā wahi haʻahaʻa haʻahaʻa. No laila, hoʻopili pinepine ʻia ka ʻili o ke aniani kiʻiʻoniʻoni me kahi ʻāpana o ke kiʻiʻoniʻoni pale silicon dioxide e hoʻokaʻawale i ka pilina pololei ma waena o ke kiʻi metala a me ka ea a pale aku i ka oxidation mai ka hoʻopili ʻana i kāna hana optical.

Panini Prisma ʻĀkau ʻĀkau

ʻO ka mea maʻamau, ua uhi ʻia ka ʻaoʻao ʻākau me kahi kiʻi anti-reflection, ʻoiai ua uhi ʻia ka ʻaoʻao slant me kahi kiʻiʻoniʻoni. Loaʻa i nā prisma ʻākau ʻākau ka ʻāpana pili nui a me nā kihi maʻamau e like me 45° a me 90°. Hoʻohālikelike ʻia me nā aniani maʻamau, ʻoi aku ka maʻalahi o nā prisms ʻākau ʻākau e hoʻokomo a ʻoi aku ka maikaʻi o ka paʻa a me ka ikaika e kūʻē i ke koʻikoʻi mechanical. ʻO lākou ke koho maikaʻi loa no nā ʻāpana optical i hoʻohana ʻia i nā mea like ʻole a me nā mea kani.

Nā aniani Parabolic axis off-axis

ʻO ke aniani parabolic off-axis he aniani ili nona ka ʻili hoʻohālikelike he ʻāpana ʻoki ʻia o kahi paraboloid makua. Ma ka hoʻohana ʻana i nā aniani parabolic off-axis, hiki ke hoʻopaʻa ʻia nā kaola like ʻole a i ʻole nā kumu kumu i hui ʻia. ʻO ka hoʻolālā off-axis e hiki ke hoʻokaʻawale i ke kiko kiko mai ke ala optical. He ʻoi aku ka maikaʻi o ka hoʻohana ʻana i nā aniani parabolic off-axis ma mua o nā lens. ʻAʻole lākou e hoʻokomo i ka spherical a i ʻole chromatic aberration, ʻo ia hoʻi, hiki ke hoʻopaʻa pololei ʻia nā kaola i hoʻopaʻa ʻia i kahi kiko hoʻokahi. Eia kekahi, ʻo nā kaola e hele ana ma nā aniani parabolic off-axis e mālama i ka mana kiʻekiʻe a me ka maikaʻi o ka optical no ka mea ʻaʻole i hoʻokomo nā aniani i ka lohi o ka manawa a i ʻole nā poho absorption. Hana kēia i nā aniani parabolic off-axis i kūpono no kekahi mau noi, e like me nā laser pulsed femtosecond. No ia mau lasers, he mea koʻikoʻi ka nānā pono ʻana a me ka hoʻonohonoho ʻana o ke kukuna, a hiki i nā aniani parabolic off-axis ke hāʻawi i ka pololei a me ke kūpaʻa kiʻekiʻe, e hōʻoia ana i ka nānā pono ʻana o ka kukuna laser a me nā huahana kiʻekiʻe.

Hōʻike Hōʻike Hou Hollow Roof Prism Mirror

ʻO ka prism o ka hale hollow he ʻelua prisms rectangular a me kahi papa kumu ʻehā i hana ʻia me ka mea Borofloat. Loaʻa i nā mea Borofloat ka pālahalaha kiʻekiʻe loa a me nā waiwai optical maikaʻi loa, e hōʻike ana i ke aniani maikaʻi loa a me ka haʻahaʻa haʻahaʻa o ka fluorescence i ka laulā holoʻokoʻa. Eia kekahi, ua uhi ʻia nā bevels o nā prisms ʻākau me kahi ʻāpana kālā me kahi pale pale metala, e hāʻawi ana i ka noʻonoʻo kiʻekiʻe i ka ʻike ʻike a kokoke i ka infrared. Hoʻonoho ʻia nā pali o nā prisma ʻelua i kahi kūʻē kekahi i kekahi, a ua hoʻonohonoho ʻia ka huina dihedral i 90±10 arcsec. Hōʻike ka mea hōʻike hollow roof prism reflector i ka hanana māmā ma ka hypotenuse o ka prisma mai waho. ʻAʻole like me nā aniani palahalaha, ʻo ke kukui i hoʻohālikelike ʻia e hoʻolike like me ke kukui i hana ʻia, e pale ana i ka hoʻopilikia ʻana i ke kukui. Hiki iā ia ke hoʻokō pololei ma mua o ka hoʻoponopono lima ʻana i nā aniani ʻelua.
