Aan Polarizing ahayn
Cube Beamsplitters
Paralight Optics waxay bixisaa alwaaxyo cube ah oo laga heli karo moodooyinka polarizing ama kuwa aan dabaylaha ahayn. Alwaaxyada cube-ku-salaysan waxay u kala qaybin doonaan iftiinka gobollada s- iyo p-polarization si kala duwan taasoo u oggolaanaysa isticmaaluhu inuu ku daro nalka dabaylaha nidaamka. Halka alwaaxyada cube ee aan dabaylaha ahayn loo nashqadeeyay in lagu kala saaro iftiinka dhacdada iyadoo loo eegayo saami qaybsan oo ka madax banaan hirarka iftiinka ama xaalada polarization. In kasta oo alwaaxyada aan-polarizing-ka ahayn si gaar ah loo kontroolo si aan loo beddelin dawladaha S iyo P ee iftiinka soo socda, marka la eego iftiinka gelinta ee aan kala sooc lahayn, wali waxaa jiri doona saameynaha kala soocida, taas macnaheedu waa in ay jiraan farqi u dhexeeya milicsiga iyo gudbinta S iyo P pol., laakiin waxay ku xiran yihiin nooca beamsplitter gaar ah. Haddi dawladaha polarization-ka aanay muhiim u ahayn codsigaaga, waxa aanu kugula talinaynaa in aad isticmaashid alwaaxyo aan polarizing ahayn.
Biamsplitters non-polarizing waxay asal ahaan iftiinka u kala qaybiyaan saamiga R/T ee gaarka ah 10:90, 30:70, 50:50, 70:30, ama 90:10 iyadoo la ilaalinayo xaaladda iftiinka asalka ah ee iftiinka. Tusaale ahaan, marka laga hadlayo 50/50 beamsplitter-ka aan dabaylaha ahayn, dawladaha P iyo S polarization ee la kala qaado iyo P iyo S polarization states waxay ku kala qaybsan yihiin saamiga naqshadaynta. Biamsplitters-yadani waxay ku habboon yihiin ilaalinta polaration-ka ee codsiyada isticmaalka iftiinka dalalka. Dichroic Beamsplitters waxay iftiinka u qaybiyaan hirarka dhererka. Ikhtiyaarada waxay u dhexeeyaan isku-dariyeyaasha iftiinka laysarka ee loogu talagalay mawjadaha dhererka leysarka gaarka ah ilaa muraayadaha ballaaran ee kulul iyo qabow ee kala qaybinta iftiinka muuqda iyo kuwa infrared. Dichroic beamsplitters ayaa inta badan loo isticmaalaa codsiyada fluorescence.
