Brewster Windows idafite igihombo cya P-Polarisation

Brewster Windows ni insimburangingo idashobora gukoreshwa murukurikirane nka polarizeri, cyangwa guhanagura igice cyigice. Iyo ihagaze kuri Angle ya Brewster, igice cya P-polarize yumucyo cyinjira kandi gisohoka mu idirishya nta gihombo kigaragaza, mugihe S-polarize igaragara igice. Ubuso bwa 20-10 bushushanya ubuziranenge hamwe na λ / 10 byanduye ikosa rya Windows ya Brewster ya Windows bituma bahitamo neza kuburwo bwa laser.

Windows ya Brewster isanzwe ikoreshwa nka polarizeri mumyanya ya laser. Iyo ishyizwe ku mfuruka ya Brewster (55 ° 32 ′ kuri 633 nm), igice cya P-polarize yumucyo kizanyura mu idirishya nta gihombo, mugihe igice cyigice cya S-polarize kizagaragarira mumadirishya ya Brewster. Iyo ikoreshejwe mu cyuho cya laser, idirishya rya Brewster rikora nka polarizeri.
Inguni ya Brewster itangwa na
tan (θB) = nt/ni
θBni Brewster
nini indangagaciro yo kugabanya ibyabaye hagati, ni 1.0003 kumyuka
ntni indangagaciro yo kugabanya uburyo bwo kohereza, ni 1.45701 kuri silika yahujwe kuri 633 nm

Paralight Optics itanga Windows ya Brewster yahimbwe kuva N-BK7 (Grade A) cyangwa UV ya silika ya silike, yerekana ko nta fluorescence iterwa na laser (nkuko byapimwe kuri 193 nm), bigatuma ihitamo neza kubisabwa kuva UV kugera kuri IR hafi ya IR . Nyamuneka reba Igishushanyo gikurikira cyerekana kwigaragaza kuri S- na P-polarisiyasi binyuze muri UV yahujwe na silika kuri 633 nm kugirango ubone.

Igishushanyo cya

Brewster Window

Igishushanyo cyerekana ibumoso cyerekana urumuri rwa S-polarize no kohereza urumuri P-polarize binyuze mu idirishya rya Brewster. Itara rya S-polarize zimwe rizoherezwa mumadirishya.

Igishushanyo

Igishushanyo kiri iburyo cyerekana ibara ryabazwe ryerekana UV idashyizwe hamwe na silika ya silike itara kugirango urumuri rutandukanye ku mpande zinyuranye zibaho (Kugaragaza urumuri rwa P-polarize rujya kuri zeru ku mfuruka ya Brewster).
♦ Indangantego yo kugabanuka kwa UV yahujwe na silika iratandukanye hamwe nuburebure bwumurongo bwerekanwe mubishushanyo byibumoso bukurikira (igipimo cyabazwe cyo kugabanuka kwa UV yahujwe na silika nkibikorwa byuburebure kuva kuri 200 nm kugeza kuri 2,2 mm).
Graph Igishushanyo cyiburyo gikurikira cyerekana agaciro kabaruwe ka θB (inguni ya Brewster) nkigikorwa cyumurambararo kuva kuri 200 nm kugeza kuri 2,2 mm iyo urumuri ruva mu kirere rujya muri UV rwahujwe na silika.
