Plate Beamsplitters

Beamsplitters waa qaybo indhaha 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 dhibcaha 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 dabaylaha nidaamka indhaha. Dichroic beamsplitters waxay iftiinka ku kala qaybiyaan hirarka hirarka waxaana caadi ahaan loo adeegsadaa codsiga fluorescence si loo kala saaro dareenka kicinta iyo qiiqa.

Tusaalaha Codsiyada Codsiyada OEM

In kasta oo alwaaxyada aan-polarizing-ka ahayn ee loogu talagalay 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 qaybinta alwaaxdu halka dhabarka dambe la jeexjeexay oo AR la dahaadhay si loo yareeyo saamaynta ghosting 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.
