kristal YVO 4 ee aan la daboolin waa crystal-ka indhaha ee birefringence dhawaan la sameeyay oo si weyn loogu isticmaalo barakicinta alwaaxyada badan ee online_ah sababtoo ah kala-soociddeeda weyn.Waxa kale oo ay leedahay sifooyin farsamo oo wanaagsan oo wanaagsan marka loo eego kiristaalo birefringent thers, guryahan aadka u fiican ayaa ka dhigaya YVO4 walxo indho-indheyn oo aad muhiim u ah oo si weyn loogu isticmaalo cilmi-baarista opto-electronic, horumarka iyo warshadaha.Tusaale ahaan, nidaamka isgaadhsiinta indhaha waxa uu u baahan yahay qalab tiro badan oo YVO4 ah oo aan la xidhin, sida kuwa go'doonsan ee fiber indhaha, wareegtada, barakicinta laydhka, Glan polarizers iyo aaladaha kale ee polarizing.
Tilmaam:
● Waxay leedahay gudbinta aad u wanaagsan ee mawjadaha dhererka ballaaran ee muuqda ilaa infrared.
● Waxay leedahay tusmaynta dib-u-soo-celinta sare iyo farqiga kala-duwanaanta.
● Marka la barbar dhigo kiristaalo kale oo muhiim ah, YVO4 ayaa ka sarreeya.qallafsanaanta, hantida wax-soo-saarka ee ka wanaagsan, iyo biyo la'aanta marka loo eego calcite (CaCO3 hal crystal).
● Way fududahay in la sameeyo crystal tayo sare leh oo ka qiimo jaban Rutile (TiO2 single crystal).
