Daaqadaha Brewster oo aan lahayn khasaare milicsi ee P-Polarization

Daaqadaha Brewster waa substrates aan la dahaadhayn oo si taxane ah loogu isticmaali karo sidii polarizers, ama in lagu nadiifiyo laydhka qayb ka mid ah. Marka la dhigo xagasha Brewster's, qaybta P-polarized ee iftiinka ayaa soo gasha oo ka baxda daaqada iyada oo aan wax khasaare ah lahayn, halka qaybta S-polarized ay qayb ahaan ka muuqato. 20-10 tayada dusha xoq-qoda iyo λ/10 ee la kala qaado khaladka hore ee mowjadda daaqadahayada Brewster ayaa ka dhigaya doorasho ku habboon godadka laysarka.

Tusaalaha Codsiyada Codsiyada OEM

Daaqadaha brewster waxaa caadi ahaan loo isticmaalaa sidii polarizers gudaha godadka laysarka. Marka la dhigo xagasha Brewster's (55° 32′ at 633 nm), qaybta P-polarized ee iftiinka waxay ka gudbi doontaa daaqada iyada oo aan wax khasaare ahi jirin, halka qayb ka mid ah qaybta S-polarized ay ka muuqan doonto daaqadda Brewster. Marka lagu isticmaalo godka laysarka, daaqada Brewster waxay asal ahaan u shaqeysaa sidii polarizer.
Xagasha Brewster waxaa bixiya
tan (θ_B) = n_t/n_i
θ_Bwaa xagasha Brewster
n_iwaa index of refraction ee dhexdhexaadka ah dhacdada, taas oo ah 1.0003 hawada
n_twaa tusaha dib-u-celinta dhexdhexaadinta gudbinta, taas oo ah 1.45701 ee silica isku dhafan ee 633 nm

Paralight Optics waxay bixisaa daaqadaha Brewster laga soo sameeyay N-BK7 (Grade A) ama UV fused silica, taas oo muujinaysa wax-soo-saarka leysarka (sida lagu cabbiro 193 nm), taasoo ka dhigaysa doorasho ku habboon codsiyada UV ilaa IR u dhow. . Fadlan eeg garaafka soo socda oo muujinaya milicsiga S- iyo P-polarization labadaba UV silica fused at 633 nm tixraacyadaada.
