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.
The customized transducers based on long experiences and proven result with past development records over 1,500 kinds of transducers.

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 |
