Abstract: Described herein is a lens having at least one object-side and at least one image-side refractive surface. In order to determine a light intensity of an effective luminous flux propagating through the lens without the need for additional components for coupling light out, the lens includes a reflective surface arranged between the object-side and the image-side refractive surfaces and aligned obliquely to the optical axis.

Abstract: A dishwasher includes a dishwashing compartment having a loading opening which can be closed by a door configured. At least one washware basket is provided for movement out of and into the dishwashing compartment, with at least one movement position of the washware basket being recognized by a device. At least one light source is arranged in or on the dishwasher and controlled by a control device in dependence on the at least one movement position of the washware basket.

Abstract: The fluid line between a drain opening at the bottom of the tub and an opening located at a higher level in the tub includes a line segment, which serves solely to keep the washwater in the tub in circulation between the upper opening and the drain opening. The line also has a solid pipe segment with a transparent region, at the wall of which a sensor is mounted that responds to the turbidity of the washwater. The sensor has an optical transmitter and an optical receiver. The sensor elements are built into a forked housing so as to securely mount and protect the sensor from the severe shaking during spin cycles. The forked housing embraces the pipe segment and the housing is adapted to the outer shape of the pipe segment at the faces which are in contact with the transparent region.
