Umfanekiso obonisiweyo weMeta yoXinzelelo loMda

Imitha yoXinzelelo lomda

Inkcazo emfutshane:

I-Edge Stress Meter isetyenziselwa ukulinganisa uxinzelelo kumphetho weglasi ngokuhambelana nendlela yokulinganisa yeSenarmont Compensation. Yenziwe ngeswitshi, ikhatriji yebhetri, i-locating pole, i-lightbox, i-polarizing sheet kunye ne-scaleplate, i-polarization analyzer kunye ne-1/4 wave plate, i-scale dial kunye ne-eyepiece.

I-Polarization analyzer ivula ngokucacileyo: 70mm

Umthombo wokukhanya: ukukhanya kwe-LED

Amandla: iibhetri ezomileyo ezi-2 #1

Isisombululo sokudayela sesikali sohlalutyo lwe-polarization: 2 °

Ukuphakama kwendawo yokulinganisa: 30mm

Umgaqo woLinganiselo

I-axis ye-Polarizer yi-45 degrees; Icala le-quarter-wave le-slow ray yi-45 degrees. I-axis ye-analyzer yi--45 degrees. Isampuli ibekwa phakathi kwe-polarizer kunye ne-quarter-wave plate.

Ngaphandle kwesampuli, umbono uba mnyama. Xa kufakwa iglasi ene-axis yoxinzelelo oluphambili, kuvela umphetho omnyama we-isochromatic, oyindawo apho kukho uxinzelelo oluyi-zero. Umahluko wendlela yokukhanya obangelwa luxinzelelo oluphambili unokulinganiswa ngale ndlela: jikelezisa i-analyzer ude umbala wokuphazamiseka uphele (ukuba ukuphambuka kwendlela yokukhanya ku-zero, umbala umnyama). Umahluko wendlela yokukhanya yendawo yokulinganisa unokubalwa nge-engile yokujikeleza.

Ifomula yile

T: Umahluko wendlela yokukhanya yendawo elinganisiweyo

λ: Ubude begagasi lokukhanya, 560nm

θ: I-engile yokujikeleza kwe-polarization analyzer

Indlela yokujikeleza i-polarization ngokwayo inokulinganisa kuphela ixabiso le-decimal order yomahluko wendlela ye-optical, kwaye inani le-integer order yee-fringes limiselwa emva kokumiselwa kwee-zero-order fringes. Ixabiso lokwenyani lomahluko wendlela ye-optical sisiphumo senani le-integer order yee-fringes kunye nexabiso le-decimal order yomahluko wendlela ye-optical.
