Title: Acoustic optical element
Inventor: TANAKA FUMIO
IPC: G02F1/11
Filed: 1990-10-18
Abstract: PURPOSE:To obtain an element which can produce the uniform radiation of supersonic energy, and is less in influence to an optical beam and excellent in reliability by covering an electrode, except its one end, provided on a piezoelectric element with a solder regist film, and connecting lead wires at the end of the electrode using a solder. CONSTITUTION:The second electrode 4b is provided on the back of an piezoelectric element 2. A solder regist film 10 having organic material as main component is provided on the electrode 4b except a part whose length is L2-L1 from the one end of the electrode 4b for covering it. A lead wire 6 is connected to a connecting part 8b at the exposed part of the electrode 4b through the solder. When an electrical signal issued from an electric power source is applied to the element, a supersonic signal is generated within the range of L2XH by the piezoelectric element 2, but absorbed in the connecting part 8b, and the signal belonging to the range of L1XH is emitted to an acoustic optical medium 1. If the connecting part 8b is formed into a proper size, a supersonic wave can be abundantly absorbed symmetrically to a A-axis. Thus supersonic energy can be uniformly radiated to the acoustic optical medium 1 to secure reliability in the connection of the lead wire 6.
