Title:
ACOUSTIC LENS, METHOD FOR MANUFACTURING SAME, AND ACOUSTIC WAVE PROBE
Document Type and Number:
WIPO Patent Application WO/2019/142547
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: an acoustic lens which is for propagating a sound wave having a wavelength λ of 100 μm or less and can exhibit excellent acoustic characteristics depending on the wavelength λ of the sound wave to be propagated; and a method for manufacturing said acoustic lens. This acoustic lens 1 is used to propagate a sound wave having a wavelength λ of 100 μm or less and is formed by including a silicone resin and silica particles, wherein the average primary particle diameter of the silica particles is 15 nm or more and the particle diameter (D90) of a 90% cumulative percentage in the cumulative particle size distribution of the silica particles is less than 1/8 of the wavelength λ of the propagating sound wave.
