Abstract

PURPOSE:To incorporate internally a light level regulating function in a semiconductor light receiver by disposing a movable lens between an input optical fiber and photoreceptor for receiving the output light from the optical fiber. CONSTITUTION:The light received from an input optifal fiber 1 becomes a light beam 6, and is applied to a photoreceptor 2. A condenser lens 3 is provided between the optical fiber 1 and the photoreceptor 2. The lens 3 is moved elevationally by an adjustment screw 7-1, and a photoreceptor base 10 is moved longitudinally by an adjustment screw 7-2 for their adjustments.
