Iintlobo zezibuko

Isibuko sePlanethi
I-1.Isibuko sokugqoka i-Dielectric: Isibuko sokugqoka i-Dielectric yi-multi-layer dielectric coating efakwe kumphezulu we-optical element, evelisa ukuphazamiseka kunye nokuphucula ukubonakaliswa kwinqanaba elithile le-wavelength. Ingubo ye-dielectric inokubonakala okuphezulu kwaye inokusetyenziswa kuluhlu olubanzi lwamaza. Azikufunxa ukukhanya kwaye zilukhuni ngokwentelekiso, ngoko azonakaliswa lula. Zifanelekile kwiinkqubo ze-optical usebenzisa i-laser multi-wavelength. Nangona kunjalo, olu hlobo lwesibuko lunomqolo ongqindilili wefilimu, lunovelwano kwi-engile yesiganeko, kwaye lunexabiso eliphezulu.

I-2.I-Laser Rays Mirror: Isiseko sesiseko sesibuko se-laser rays yi-silica edibeneyo ye-ultraviolet, kunye nefilimu ephezulu yokubonakalisa ifilimu kwindawo yayo yifilimu ye-dielectric ye-Nd: YAG, efakwe yi-electron beam evaporation kunye ne-ion-assisted deposition process. Xa kuthelekiswa nezinto ze-K9, i-silica edibeneyo ye-UV inokufaniswa okungcono kunye ne-coefficient ephantsi yokwandiswa kwe-thermal, iyenza ifaneleke ngokukodwa usetyenziso kwi-ultraviolet ukuya kufuphi noluhlu lwe-infrared wavelength, iilaser zamandla aphezulu kunye neendawo zokucinga. Ubude obuqhelekileyo bokusebenza kwizibuko zemitha yelaser ziquka i-266 nm, 355 nm, 532 nm, kunye ne-1064 nm. I-angle yesiganeko ingaba ngu-0-45 ° okanye i-45 °, kwaye i-reflectivity idlula i-97%.

I-3.Isibuko se-Ultrafast: Isiseko sesiseko sesibuko se-ultrafast yi-silica edibeneyo ye-ultraviolet, kunye nefilimu ephezulu yokubonakalisa ifilimu ebusweni bayo liqela eliphantsi lokulibaziseka kwefilimu ye-dielectric dielectric, eyenziwa yinkqubo ye-ion beam sputtering (IBS). I-silica edityanisiweyo ye-UV ine-coefficient ephantsi yokwandiswa kwe-thermal kunye nokuzinza okuphezulu kwe-thermal, iyenza ilungele amandla aphezulu e-femtosecond pulsed lasers kunye nokusetyenziswa kwe-imaging. Iindidi zobude obuqhelekileyo bobude bezibuko ze-ultrafast ziyi-460 nm-590 nm, 700 nm-930 nm, 970 nm-1150 nm, kunye ne-1400 nm-1700 nm. I-beam yesiganeko yi-45 ° kwaye i-reflectivity idlula i-99.5%.

I-4.Izipili ze-Supermirrors: Ii-Supermirrors zenziwe ngokubeka iileya ezitshintshileyo ze-dielectric index ephezulu kunye ne-low refractive index kwi-UV fused silica substrate. Ngokunyusa inani leengqimba, ukubonakaliswa kwe-super-reflector kungaphuculwa, kwaye ukubonakaliswa kudlula i-99.99% kwi-design wavelength. Oku kuyenza ilungele iinkqubo zamehlo ezifuna ukubonakaliswa okuphezulu.

I-5.Metallic Mirrors: Izibuko zentsimbi zilungele ukuphambukisa imithombo yokukhanya kwebroadband, kunye nokukhanya okuphezulu kuluhlu olubanzi lwe-spectral. Iifilimu zetsimbi ziqhelene ne-oxidation, i-discoloration okanye i-peeling off kwiindawo zokufuma okuphezulu. Ke ngoko, umphezulu wesibuko sefilimu yesinyithi udla ngokugqunywa ngomaleko we-silicon dioxide ifilimu ekhuselayo ukwahlula unxibelelwano oluthe ngqo phakathi kwefilimu yentsimbi kunye nomoya kunye nokuthintela i-oxidation ekuchaphazeleni ukusebenza kwayo kwamehlo.

I-Angle ye-Prism Mirror yasekunene

Ngokuqhelekileyo, i-angle-angle ekunene ifakwe ifilimu echasene ne-reflection, ngelixa i-slant side ifakwe ifilimu ebonakalisayo. Iiprism ze-right-angle zinendawo enkulu yoqhagamshelwano kunye nee-engile eziqhelekileyo ezifana ne-45 ° kunye ne-90 °. Xa kuthelekiswa nezibuko eziqhelekileyo, iiprism ze-right angle zilula ukuzifaka kwaye zibe nokuzinza okungcono kunye namandla ngokuchasene noxinzelelo lomatshini. Zilolona khetho lufanelekileyo lwamacandelo optical asetyenziswa kwizixhobo ezahlukeneyo kunye nezixhobo.

I-Off-axis Parabolic Mirror

I-off-axis parabolic mirror sisipili esingaphezulu esinomphezulu obonakalisayo yinxalenye enqunyiweyo yeparaboloid yomzali. Ngokusebenzisa izibuko zeparabolic ezingaphandle kwe-axis, imiqadi enxuseneyo okanye imithombo yamanqaku adityanisiweyo inokujoliswa. Uyilo lwe-off-axis luvumela ukwahlulwa kwendawo ekugxilwe kuyo ukusuka kwindlela yokubona. Ukusebenzisa i-off-axis parabolic mirror kuneenzuzo ezininzi kwiilensi. Abazisi uphambuko olungqukuva okanye lwechromatic, okuthetha ukuba imiqadi egxininisiweyo inokujoliswa ngokuchanekileyo ngakumbi kwinqaku elinye. Ukongeza, imiqadi edlula kwizibuko zeparabolic ezingaphandle kwe-axis zigcina amandla aphezulu kunye nomgangatho we-optical kuba izibuko azibonisi kulibaziseka kwesigaba okanye ilahleko yokufunxa. Oku kwenza izibuko zeparabolic ezingaphandle kwe-axis zilungele ngakumbi usetyenziso oluthile, njenge-laser ye-femtosecond pulsed lasers. Kwiilaser ezinjalo, ukugxila ngokuchanekileyo kunye nokulungelelaniswa kwe-beam kubalulekile, kwaye izibuko ze-parabolic ezingaphandle kwe-axis zinokubonelela ngokuchaneka okuphezulu kunye nokuzinza, ukuqinisekisa ukugxila okusebenzayo kwe-laser beam kunye nemveliso ekumgangatho ophezulu.

Ukubuyisela umva kwiHollow Roof Mirror yePrism

Iprism yophahla olungenamngxuma luqukethe iiprism ezimbini ezixande kunye nesiseko soxande esenziwe ngezinto zeBorofloat. Imathiriyeli yeBorofloat inomgangatho othe tyaba ophezulu kakhulu kunye neempawu ezibalaseleyo zamehlo, zibonisa ukungafihli okugqwesileyo kunye nokuqina kwefluorescence ephantsi kakhulu kulo lonke uluhlu lokubonwayo. Ukongezelela, ii-bevels ze-prisms ze-angle-angle ziboshwe ngesilivere yesilivere kunye noluhlu olukhuselayo lwetsimbi, olubonelela ngokukhanya okuphezulu kwibala elibonakalayo kunye ne-infrared. Imithambeka yeeprism ezimbini zibekwe ngokuchaseneyo, kwaye i-angle ye-dihedral isetelwe kwi-90±10 arcsec. Isibonisi seprism yophahla olunomngxuma sibonisa isehlo esilula kwi-hypotenuse yeprism evela ngaphandle. Ngokungafaniyo nezibuko ezicaba, ukukhanya okubonakalisiweyo kuhlala kuhambelana nokukhanya kwesiganeko, ukuphepha ukuphazamiseka kwe-beam. Ivumela ukuphunyezwa ngokuchanekileyo ngakumbi kunokulungelelanisa ngesandla izibuko ezimbini.
