Ultrasonic probe is a very important sensor which generate acoustic signals and also detect returned signals. The performance and imaging quality of ultrasonic scanner are highly affected by the characteristic and the structure(piezoelectric material, matching layer and acoustic lens) of probe.
NDK has a probe line up for each application and can produce customer's designed products.

Frequency and Resolution

High frequency probe can get the fine imaging with good resolution.
However the imaging of deep part will be smudgy due to wave length is short.
Meanwhile the imaging resolution of low frequency probe is low but ultrasonic wave can reach at deep part. The scanning depth and resolution are mainly determined by the frequency of probe.

Frequency	Resolution	Penetration	Possible scanning depth
High	Fine	Weak	Shallow
Low	Rough	Strong	Deep
