Title:
LIGHT RECEIVING COMPONENTS
Document Type and Number:
Japanese Patent JPH05206487
Kind Code:
A
Abstract:
PURPOSE:To provide a light receiving component which is provided with an excellent condensation characteristic which condenses much light and an electromagnetic noise cutoff effect which cuts off electromagnetic noise from different equipment in light receiving components used for an infrared remote controller or optical space transmission or the like. CONSTITUTION:A plano-convex lens 1 and a light receiving device installed on the flat portion of the lens 1 in such a fashion that its central axis may agree with that of the lens 1 are provided. What is more, a light receiving component is designed so that the conduction side of a transparent electrode 4 may come to the side of the light receiving device between the plano-convex lens 1 and a pin photodiode 5 which serves as the light receiving device. A shielding board 6 is connected to the transparent electrode 4 so as to condense much light to the light receiving component. Moreover, the light receiving component can be shielded electromagnetically.
