Izinhlobo zezibuko

Isibuko Sendiza
I-1.Isibuko sokugqoka i-Dielectric: Isibuko sokugqoka i-Dielectric iyi-multi-layer dielectric coating efakwe ebusweni be-optical element, ekhiqiza ukuphazanyiswa futhi ithuthukise ukubukeka kwebanga elithile le-wavelength. I-dielectric coating inokukhanya okuphezulu futhi ingasetshenziswa ebangeni elibanzi le-wavelength. Azikutholi ukukhanya futhi ziqinile, ngakho azilinyazwa kalula. Afaneleka kumasistimu okukhanya asebenzisa ama-laser angama-wavelength amaningi. Kodwa-ke, lolu hlobo lwesibuko lunongqimba lwefilimu oluwugqinsi, luzwela i-angle yesigameko, futhi lunezindleko eziphezulu.

2.Isibuko Semisebe Ye-Laser: Isisekelo sesibuko sesibuko semisebe ye-laser iyisilica exutshwe yi-ultraviolet, futhi ifilimu ebonisa ukukhanya okuphezulu ebusweni bayo ifilimu ye-dielectric ye-Nd:YAG, efakwa ukuhwamuka kwe-electron beam kanye nenqubo yokubeka i-ion-assisted. Uma iqhathaniswa nempahla ye-K9, i-silica ehlanganisiwe ye-UV inokufana okungcono kanye ne-coefficient ephansi yokunwetshwa okushisayo, okuyenza ifaneleke ikakhulukazi izinhlelo zokusebenza ku-ultraviolet ukuya eduze kwebanga le-wavelength le-infrared, ama-laser amandla aphezulu nezinkambu zezithombe. Amaza okusebenza ajwayelekile ezibuko zemisebe ye-laser ahlanganisa 266 nm, 355 nm, 532 nm, kanye no-1064 nm. I-engeli yesigameko ingaba ngu-0-45° noma u-45°, futhi i-reflection idlula ama-97%.

I-3.Isibuko se-Ultrafast: Izinto eziyisisekelo zesibuko se-ultrafast yi-silica ehlanganisiwe ye-ultraviolet, futhi ifilimu ye-reflectivity ephezulu ebusweni bayo ifilimu ye-dielectric yokubambezeleka kweqembu eliphansi, ekhiqizwa inqubo ye-ion beam sputtering (IBS). I-silica ehlanganisiwe ye-UV ine-coefficient ephansi yokwanda okushisayo kanye nokuzinza okuphezulu kokushisa okushisayo, okuyenza ilungele ama-laser anamandla e-femtosecond pulsed kanye nezinhlelo zokusebenza zokucabanga. Ububanzi be-wavelength obujwayelekile bokusebenza kwezibuko ezisheshayo ngu-460 nm-590 nm, 700 nm-930 nm, 970 nm-1150 nm, kanye no-1400 nm-1700 nm. I-beam yesigameko ingu-45 ° futhi ukubukeka kudlula u-99.5%.

4.Izibuko ezibukwayo: Izibuko ezibukwayo zenziwa ngokufaka izendlalelo ezishintshanayo zezinto ze-dielectric ezinenkomba ye-refractive ephezulu nephansi ku-substrate ye-silica ehlanganisiwe ye-UV. Ngokwandisa inani lezendlalelo, i-reflector ye-super-reflector ingathuthukiswa, futhi i-reflector idlula i-99.99% kubude be-design waveleng. Lokhu kuyenza ifanelekele amasistimu okubona adinga ukubukeka okuphezulu.

5.Izibuko Zensimbi: Izibuko zensimbi zilungele ukuphambukisa imithombo yokukhanya kwe-broadband, enokubonakala okuphezulu phezu kobubanzi obubanzi bokubukeka. Amafilimu ensimbi athambekele ekubeni ne-oxidation, ashintshe umbala noma axebuke ezindaweni ezinomswakama ophezulu. Ngakho-ke, ingaphezulu lesibuko sefilimu yensimbi ngokuvamile limbozwa ungqimba lwefilimu evikelayo ye-silicon dioxide ukuze ihlukanise ukuxhumana okuqondile phakathi kwefilimu yensimbi nomoya futhi ivimbele i-oxidation ukuthi ithinte ukusebenza kwayo kokubona.

I-Angle Prism Mirror

Ngokuvamile, uhlangothi lwe-engeli yesokudla lumbozwe ngefilimu ephikisana ne-reflection, kuyilapho uhlangothi lwe-slint lumbozwe ngefilimu ekhanyayo. Amaprism e-engeli yesokudla anendawo yokuxhumana enkulu nama-engeli ajwayelekile afana no-45° no-90°. Uma kuqhathaniswa nezibuko ezivamile, ama-prism e-engeli engakwesokudla kulula ukuzifaka futhi abe nokuzinza okungcono namandla ngokumelene nokucindezeleka komshini. Ziyinketho efanelekile yezingxenye ze-optical ezisetshenziswa kumadivayisi ahlukahlukene namathuluzi.

I-Off-axis Parabolic Mirror

I-off-axis parabolic mirror iyisibuko esingaphezulu esibuso baso obukhanyayo buyingxenye yokusika ye-paraboloid yomzali. Ngokusebenzisa izibuko ze-parabolic off-axis, imishayo ehambisanayo noma imithombo yamaphuzu ahlanganisiwe ingagxilwa. Idizayini ye-off-axis ivumela ukuhlukaniswa kwendawo okugxilwe kuyo endleleni yokubona. Ukusebenzisa izibuko ze-parabolic off-axis kunezinzuzo ezimbalwa ngaphezu kwamalensi. Akwethusi i-spherical or chromatic aberration, okusho ukuthi imishayo egxilile ingagxilwa ngokunembe kakhudlwana ephuzwini elilodwa. Ngaphezu kwalokho, imishayo edlula ezibukweni ze-parabolic off-axis igcina amandla aphezulu kanye nekhwalithi yokubona njengoba izibuko zingethuli ukubambezeleka kwesigaba noma ukulahlekelwa kokumuncwa. Lokhu kwenza izibuko ze-parabolic ezingaphandle kwe-axis zifaneleke ikakhulukazi izinhlelo zokusebenza ezithile, njengamalaser e-femtosecond pulsed lasers. Kuma-laser anjalo, ukugxila okunembile nokuqondanisa kwe-beam kubalulekile, futhi izibuko ze-parabolic ezingaphandle kwe-axis zinganikeza ukunemba okuphezulu nokuzinza, ziqinisekise ukugxila okuphumelelayo kwe-laser beam kanye nokuphumayo kwekhwalithi ephezulu.

I-Retroreflecting Hollow Roof Mirror yePrism

I-prism yophahla olungenalutho iqukethe ama-prism amabili angama-rectangular kanye ne-base plate engunxande eyenziwe ngezinto ze-Borofloat. Izinto ze-Borofloat zinokugqama okuphezulu kakhulu kwendawo kanye nezakhiwo ezinhle kakhulu zokubona, ezibonisa ukukhanya okuhle kakhulu kanye namandla e-fluorescence aphansi kakhulu kulo lonke uhla lwe-spectral. Ngaphezu kwalokho, ama-bevels ama-prism e-angle elungile ahlanganiswe nesiliva enesendlalelo sokuzivikela sensimbi, esihlinzeka ngokubonakala okuphezulu ebangeni elibonakalayo neliseduze ne-infrared. Imithambeka yamaprism amabili ibekwe ngokuphambana, futhi i-engeli ye-dihedral isethelwe ku-90±10 arcsec. Isibonisi seprism sophahla esingenalutho sibonisa isigameko esilula ku-hypotenuse yeprism ngaphandle. Ngokungafani nezibuko eziyisicaba, ukukhanya okubonisiwe kuhlala kuhambisana nokukhanya kwesigameko, kugwema ukuphazamiseka kwe-beam. Ivumela ukuqaliswa okunembe kakhudlwana kunokulungisa mathupha izibuko ezimbili.
