Plate Beamsplitters

Beamsplitters waa qaybo indho-indhayn ah oo iftiinka u kala qaybiya laba jiho.Tusaale ahaan waxaa sida caadiga ah loo isticmaalaa interferometers si hal alwaax uu naftiisa u farageliyo.Guud ahaan waxaa jira dhowr nooc oo kala duwan oo ah alwaaxyada: saxan, cube, pellicle iyo alwaaxyada dhibicda polka.Biamsplitter-ka caadiga ah wuxuu u qaybiyaa beam boqolkiiba xoojinta, sida 50% gudbinta iyo 50% milicsiga ama 30% gudbinta iyo 70% milicsiga.Biamsplitters non-polarizing si gaar ah ayaa loo xakameeyaa si aan loo beddelin dawladaha S iyo P ee iftiinka soo socda.Biamsplitters polarized-ka ayaa gudbin doona iftiinka P-polarized waxayna ka tarjumaysaa iftiinka S, taasoo u oggolaanaysa isticmaalayaasha inay ku daraan nalka polarized nidaamka indhaha.Dichroic beamsplitters waxay iftiinka u kala qaybiyaan hirarka hirarka waxaana caadi ahaan loo adeegsadaa codsiga fluorescence si loo kala saaro dariiqa kicinta iyo sii daynta.

In kasta oo alwaaxyada aan-polarizing-ka ahayn loo qorsheeyay in aanay beddelin dawladaha S iyo P polarization ee iftiinka soo socda, haddana weli waxay u nugul yihiin iftiinka dabaylaha, taas macnaheedu waa inay wali jiri doonaan saameynaha polarization-ka haddii alwaaxyada aan-polarizing-ka ahayn la siiyo iftiinka gelinta ee aan kala sooc lahayn. .Si kastaba ha ahaatee, alwaaxyadayada kala-baxa ah ma noqon doonaan kuwo xasaasi u ah kala soocida iftiinka dhacdada, farqiga u dhexeeya milicsiga iyo gudbinta S- iyo P-pol.waxay ka yar tahay 5%, ama xitaa ma jiro farqi u dhexeeya milicsiga iyo gudbinta S- iyo P-pol ee hirarka dhererka ee naqshadeynta qaarkood.Fadlan ka eeg jaantusyada soo socda tixraacyadaada.

Paralight Optics waxay soo bandhigtaa noocyo badan oo alwaaxyada indhaha ah.Biamsplitters saxankeenu waxay leeyihiin dusha hore ee dahaarka taas oo go'aamisa saamiga kala qaybsanaanta alwaaxdu halka dhabarka dambe la jeexjeexay oo AR la dahaadhay si loo yareeyo saamaynta rooxaanta iyo faragelinta.Alwaaxyadayada cube-ga ayaa lagu heli karaa moodooyinka polarizing ama non-polarizing.Beamsplitters Pellicle waxay bixiyaan sifooyin gudbinta mowjadda hore oo aad u wanaagsan iyagoo meesha ka saaraya biimka iyo ghosting.Dichroic beamsplitters waxay soo bandhigaan sifooyin kala-baxa kuwaas oo ku xiran mowjadaha dhererka.Waxay faa'iido u leeyihiin in la isku daro / kala qaybiyo laydhka laysarka ee midabada kala duwan.
