Brewster Windows ngaphandle kweReflection ilahleko yeP-Polarization
Iifestile zeBrewster zidla ngokusetyenziswa njengezinto zokuphola ngaphakathi kwimingxuma yelaser. Xa ibekwe kwi-angle ye-Brewster (55 ° 32′ kwi-633 nm), inxalenye ye-P-polarized yokukhanya iya kudlula kwifestile ngaphandle kwelahleko, ngelixa i-fraction ye-S-polarized section iya kubonakaliswa kwifestile yeBrewster. Xa isetyenziswe kwindawo yelaser, ifestile yeBrewster isebenza njengepolarizer.
I-angle kaBrewster inikwe ngu
tan(θB) = nt/ni
θByi-engile kaBrewster
niIsalathiso sokuphinda siphindeke sesiganeko esiphakathi, esiyi-1.0003 emoyeni
ntIsalathiso sokuphindaphinda kwendlela yokudlulisa, eyi-1.45701 ye-silica edibeneyo kwi-633 nm.
IParalight Optics ibonelela ngeefestile zeBrewster zenziwe nge-N-BK7 (iBanga A) okanye i-silica edityanisiweyo ye-UV, ebonisa ukuba akukho fluorescence eyenziwe ngelaser (njengoko ilinganiswe kwi-193 nm), iyenza ibe lolona khetho lufanelekileyo lwezicelo ezisuka kwi-UV ukuya kwi-IR ekufutshane. . Nceda ujonge le Grafu ilandelayo ebonisa imbonakalo yazo zombini i-S- kunye ne-P-polarization nge-silica edityanisiweyo ye-UV kwi-633 nm yeembekiselo zakho.
Iimbonakalo:

Umzobo weReferensi ye
Brewster Window
Umzobo wereferensi ngakwesobunxele ubonisa ukubonakaliswa kokukhanya kwe-S-polarized kunye nokuhanjiswa kokukhanya kwe-P-polarized ngefestile yeBrewster. Okunye ukukhanya kwe-S kuya kuhanjiswa ngefestile.

Iigrafu
♦ Igrafu esekunene ibonisa imbonakaliso ebaliweyo yesilica edityanisiweyo ye-UV yokukhanya okumhlophe kwii-engile ezahlukeneyo zezehlo (Isibonakaliso sokukhanya kwe-P-polarized siya ku-zero kwi-engile ye-Brewster).
♦ Isalathiso se-refraction ye-silica edibeneyo ye-UV iyahluka kunye ne-wavelength eboniswe kwigrafu elandelayo yesandla sasekhohlo (isalathisi esibaliweyo se-refraction ye-silica edibeneyo ye-UV njengomsebenzi we-wavelength ukusuka kwi-200 nm ukuya kwi-2.2 μm).
♦ Le grafu ilandelayo ngasekunene ibonisa ixabiso elibaliweyo le-θB (i-angle ye-Brewster) njengomsebenzi we-wavelength ukusuka kwi-200 nm ukuya kwi-2.2 μm xa ukukhanya kudlula emoyeni ukuya kwi-silica edibeneyo ye-UV.
Isalathiso se-refraction sixhomekeke kwi-Wavelength
