CLI 1500 UBM Imaging Probes
There is no better way of preserving the high-frequency component of the transmitted acoustic waveform than to scan through a water path. Using this method, the piezo element is immersed directly into a bath of water (i.e., no intervening window) and swept through an arc at the end of a pendulum. This produces a pronounced trapezoidal image of very high quality. Alternatively, a thin membrane may be used to capture the water path and convert the probe to a contact scanning probe.
The heart of the CLI probe is a sealed, nickel plated assembly containing most of the functional components of the probe. A plastic housing, or “cover”, is applied over this assembly to provide custom design elements. These covers can be designed by CLI or by the customer. A sample design is included below.
Additionally, the probe may be used with or without a sealed nosepiece. When used, the nosepiece opening is covered by a clear thin membrane that allows contact scanning through a short water path. Without the nosepiece, scanning is done through an open water “bath” (e.g., an eyecup or goggle for ophthalmic imaging).
