A lens plate (18) for an optical sensor device in a vehicle, in particular for a rain sensor, with a transmitter-side lens structure (26) and a receiver-side lens structure (32), wherein the transmitter-side lens structure (26) partially is provided with anti-transmission features which in individual regions of the lens plate (18) partially or completely prevent the passage of the light emitted by a light transmitter (14), wherein light sent through the lens plate is at least partially attenuated by the anti-transmission features such that a homogeneous light distribution is obtained in an entire illuminated region of a pane.
