Nkhani - Mitundu ya Magalasi ndi Maupangiri Ogwiritsa Ntchito Magalasi

Mitundu yamagalasi

Mirror ya Ndege
1.Dielectric coating mirror: Dielectric coating mirror ndi multilayer dielectric coating yomwe imayikidwa pamwamba pa optical element, yomwe imapanga kusokoneza ndikuwonjezera kuwonetsetsa mumtundu wina wa wavelength. Chophimba cha dielectric chimakhala ndi kuwunikira kwambiri ndipo chitha kugwiritsidwa ntchito pamafunde osiyanasiyana. Sizitenga kuwala ndipo zimakhala zolimba, choncho siziwonongeka mosavuta. Ndioyenera kumawonekedwe opangira ma lasers a multi-wavelength. Komabe, galasi lamtunduwu limakhala ndi filimu yokhuthala kwambiri, imakhudzidwa ndi zochitika, ndipo imakhala ndi mtengo wapamwamba.

2.Laser Rays Mirror: Zomwe zili pansi pa galasi la laser ray ndi ultraviolet fused silica, ndipo filimu yowonetseratu pamwamba pake ndi Nd: YAG dielectric film, yomwe imayikidwa ndi electron beam evaporation ndi ion-assisted deposition process. Poyerekeza ndi zinthu za K9, silika yosakanikirana ndi UV imakhala yabwinoko komanso yocheperako pakukulitsa matenthedwe, kupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mu ultraviolet kupita kufupi ndi kutalika kwa mafunde a infrared, ma lasers amphamvu kwambiri ndi malo oyerekeza. Wavelengths wavelength ntchito magalasi laser cheza monga 266 nm, 355 nm, 532 nm, ndi 1064 nm. Chochitikacho chimatha kukhala 0-45 ° kapena 45 °, ndipo chiwonetsero chimaposa 97%.

3.Ultrafast mirror: Zida zapansi za galasi la ultrafast ndi ultraviolet fused silica, ndipo filimu yowonetsera kwambiri pamwamba pake ndi gulu lochepa lochedwa dispersion dielectric film, lomwe limapangidwa ndi ndondomeko ya ion beam sputtering (IBS). Silika yosakanikirana ya UV imakhala ndi gawo lotsika la kukulitsa kwamafuta komanso kukhazikika kwamphamvu kwamafuta, kupangitsa kuti ikhale yabwino kwa ma laser amphamvu kwambiri a femtosecond pulsed lasers ndi kugwiritsa ntchito kujambula. Mawonekedwe a kutalika kwa magalasi a ultrafast ndi 460 nm-590 nm, 700 nm-930 nm, 970 nm-1150 nm, ndi 1400 nm-1700 nm. Mtengo wa zochitika ndi 45 ° ndipo chiwonetsero chimaposa 99.5%.

4.Supermirrors: Ma Supermirror amapangidwa poyika zigawo zosinthika za zida za dielectric zapamwamba komanso zotsika pamtundu wa silika wosakanikirana wa UV. Powonjezera kuchuluka kwa zigawo, chiwonetsero cha super-reflector chikhoza kusinthidwa, ndipo kuwunikira kumaposa 99.99% pakupanga mawonekedwe. Izi zimapangitsa kuti zikhale zoyenera pamakina owoneka bwino omwe amafunikira kuwunikira kwambiri.

5.Metallic Mirrors: Magalasi achitsulo ndi abwino kuti atembenuzire magwero a kuwala kwa burodibandi, okhala ndi kuwala kwakukulu pamitundu yambiri. Mafilimu achitsulo amatha kutenthedwa, kusinthika kapena kusuluka m'malo a chinyezi chambiri. Choncho, pamwamba pa galasi filimu yachitsulo nthawi zambiri yokutidwa ndi wosanjikiza silicon dioxide woteteza filimu kudzipatula kukhudzana mwachindunji pakati filimu zitsulo ndi mpweya ndi kupewa makutidwe ndi okosijeni kukhudza ntchito yake kuwala.

Right Angle Prism Mirror

Kawirikawiri, mbali ya kumanja imakutidwa ndi filimu yotsutsa-reflection, pamene mbali ya slant imakutidwa ndi filimu yowonetsera. Ma prism akumanja ali ndi malo olumikizirana okulirapo komanso makona ake monga 45 ° ndi 90 °. Poyerekeza ndi magalasi anthawi zonse, ma prism olowera kumanja ndi osavuta kuyika komanso kukhala okhazikika komanso olimba polimbana ndi kupsinjika kwamakina. Ndiwo chisankho chabwino kwambiri chazida zowoneka bwino zomwe zimagwiritsidwa ntchito pazida ndi zida zosiyanasiyana.

Off-axis Parabolic Mirror

Kalilore wakutali ndi galasi lapamtunda lomwe mawonekedwe ake ndi gawo loduka la paraboloid ya kholo. Pogwiritsa ntchito magalasi a parabolic akutali, mizati yofananira kapena magwero olumikizana amatha kuyang'ana. Mapangidwe a off-axis amalola kulekanitsa koyambira kuchokera kunjira ya kuwala. Kugwiritsa ntchito magalasi a parabolic ali ndi maubwino angapo kuposa magalasi. Sayambitsa kusintha kozungulira kapena chromatic, zomwe zikutanthauza kuti mizati yolunjika imatha kuyang'ana kwambiri pamfundo imodzi. Kuphatikiza apo, magalasi omwe amadutsa pamagalasi akutali amakhalabe ndi mphamvu zambiri komanso mawonekedwe owoneka bwino popeza magalasi samayambitsa kuchedwa kwa gawo kapena kutayika kwa mayamwidwe. Izi zimapangitsa magalasi a parabolic a off-axis kukhala oyenera pazinthu zina, monga femtosecond pulsed lasers. Kwa ma lasers oterowo, kuyang'ana bwino ndi kuyanjanitsa kwa mtengo ndikofunikira, ndipo magalasi a parabolic akutali amatha kupereka kulondola komanso kukhazikika, kuwonetsetsa kuyang'ana bwino kwa mtengo wa laser ndi kutulutsa kwapamwamba.

Retroreflecting Hollow Roof Prism Mirror

Denga lopanda dzenje lili ndi ma prism awiri amakona anayi ndi mbale yoyambira yamakona anayi yopangidwa ndi zinthu za Borofloat. Zipangizo za Borofloat zimakhala ndi mawonekedwe apamwamba kwambiri komanso mawonekedwe abwino kwambiri owoneka bwino, owonetsa bwino kwambiri komanso kutsika kwambiri kwa fulorosenti mumitundu yonse yowonera. Kuonjezera apo, ma bevel a ma prisms aang'ono oyenerera amakutidwa ndi siliva wophimba ndi zitsulo zotetezera zitsulo, zomwe zimapereka chiwonetsero chapamwamba pamtundu wowoneka ndi pafupi ndi infrared. Malo otsetsereka a ma prisms awiriwa amayikidwa moyang'anizana ndi mzake, ndipo mbali ya dihedral imayikidwa ku 90±10 arcsec. Chowonetsera padenga la prism chimawonetsa kuwala kwa prism kuchokera kunja kwa hypotenuse. Mosiyana ndi magalasi athyathyathya, kuwala kowoneka bwino kumakhalabe kofanana ndi kuwala kwa chochitikacho, kupewa kusokonezedwa ndi kuwala. Zimalola kukhazikitsidwa kolondola kwambiri kuposa kusintha pamanja magalasi awiri.
