25-100MHz
2
Q
What is the axial resolution of UBM?
A
20-100um
3
Q
What is the max axial penetration of UBM?
A
4-15mm depending on the chosen frequency.
4
Q
What frequencies should be used in UBM to image the human cornea?
A
60-80MHz
Since <1mm of penetration is needed, high frequencies that provide better axial resolution are preferred.
