High frequency polymer (PVDF) transducers are focused immersion transducers with very broad bandwidth, whose element provides an excellent impedance match to water that results in a better transfer of sound energy. These transducers also eliminate the need for the fused silica delay lines typically found in high frequency immersion transducers, removing the echo multiples associated with delay lines. Note: Polymer transducer center frequencies are
| Frequency |
Nominal Element Size |
Part Number | Standard Focal Lengths |
| MHz | inches | inches | |
| 15 | 0.25 | PI15-2-RX.XX" | 1.00 |
| 20 | 0.25 | PI20-2-RX.XX" | 0.50, 1.00, 1.50, 2.00 |
| 35 | 0.25 | PI35-2-RX.XX" | 0.50, 0.75, 1.00, 1.50, 2.00 |
| 50 | 0.25 | PI50-2-RX.XX" | 0.50, 0.75, 1.00, 1.50, 2.00 |
| 75 | 0.125 | PI75-1-RX.XX" | 0.50, 1.00 |
Note: Please replace X.XX" with the standard focal length of your choice.
• Due to the fact that polymer transducers are inherently broadband, their center frequency may be lower than the frequency indicated on the transducer
