Uniaxial cov zaub mov yog chav kawm ntawm anisotropic cov ntxhia uas suav nrog tag nrho cov ntxhia uas crystallize hauv tetragonal thiab hexagonal crystal systems. Lawv hu ua ib uniaxial vim hais tias lawv muaj ib tug optic axis. Rau uniaxial cov zaub mov cov ob qhov tseem ceeb ntawm qhov ntsuas qhov cuam tshuam tau txhais ua ω (lossis No) thiab ε (lossis Ne).

Kuj nug, dab tsi yog biaxial ntxhia?

Txhua cov ntxhia uas crystallize hauv orthorhombic, monoclinic, lossis triclinic siv lead ua tshuab yog biaxial . Zoo li uniaxial crystals, biaxial muaju muaj qhov ntsuas qhov cuam tshuam uas sib txawv ntawm ob qhov kev kub ntxhov, tab sis kuj tseem muaj qhov tshwj xeeb nruab nrab qhov cuam tshuam qhov ntsuas.

Ib tus kuj tseem yuav nug, dab tsi yog uniaxial thiab biaxial siv lead ua? Uniaxial vs Biaxial Crystals A uniaxial siv lead ua yog ib qho khoom siv kho qhov muag uas muaj ib qho optic axis. A biaxial siv lead ua yog ib qho khoom siv kho qhov muag uas muaj ob txoj hauv kev kho qhov muag. Daim ntawv tsis zoo. Qhov tsis zoo uniaxial siv lead ua muaj qhov refraction index ntawm o-ray (no) loj dua li ntawm e-ray (ne).

Tsis tas li ntawd, puas yog quartz uniaxial zoo lossis tsis zoo?

Quartz belongs rau chav kawm trigonal crystal thiab raws li yog ib uniaxial . Nws yog hu ua uniaxial zoo vim ne > no. Optical axis nyob rau hauv quartz sib raug zoo rau c-axis ntawm chav nyob ntawm tes, yog li tsis muaj kev sib txuas lus thaum lub teeb hla cov siv lead ua los ntawm qhov taub mus rau qhov taub.

Koj yuav txheeb xyuas qhov kos npe kho qhov muag ntawm cov ntxhia li cas?

Cov optic kos npe ntawm cov ntxhia ua tau txiav txim siab los ntawm kev saib tus swb uas yog saib hauv qab qhov muag axis ua ntxhia . Hauv qhov no, yuav tsum muaj tus ntoo khaub lig dub uas txhua lub teeb tau ploj mus.
