Abstract
PURPOSE: To eliminate interference stripes when coherent light is used by using an adhesive-layer material whose refractive index is nearly equal to that of a light reduction material, at the time of obtaining a pickup element by providing the light reduction material to the front surface of a sensor part via an adhesive layer and by adhering a reflection preventive film to the incident light side of this light reduction material.
CONSTITUTION: In order to prevent the generation of an air layer in sensor part 11, substrate 10 of the sensor is applied with adhesive layer 13, through which light reduction material 12 is fixed and its surface is covered with reflection preventive film 14. In this way, the solid pickup element is constituted, but adhesive layer 13 employs a material whose refractive index is nearly equal to that of light reduction material 12. In addition, light reduction material 12 employs a material of 35% in light transmissive index, and the refractive index of this incident surface is fixed below 0.5%. As a result, the visibility of interference becomes below 3% even when coherent light is used, and interference stripes generated becomes small enough to be ignored actually.
