Document Type and Number:
Japanese Patent JP4986936
Kind Code:
B2
Abstract:
The device has a sensor unit (12) comprising an emitter (26), a receiver (28) and a light conductor unit (30). The light conductor unit is placed such that a light beam emitted by the emitter is coupled to a window (14), where the coupled light of the window is directed onto the receiver. The light conductor unit includes fresnel lens regions and reflecting regions associated to the fresnel lens regions. The fresnel lens regions and the reflecting regions are formed in a stepped structure of the light conductor unit. An independent claim is also included for a method for producing an optical sensor device.
