• Recommended for applications where resolution is the primary consideration.
• Suitable for applications such as thickness measurement and near-surface flaw detection.
• Very short pulse—mechanically damped to the limit of current technology.
• Gain is usually lower than that of the Gamma and Benchmark Series.
• Broadband—typical 6 dB bandwidths range from 50% to 100%.
• Typical Alpha waveforms (right) exhibit one to two full ring cycles, depending on frequency, size and
other parameters.
