Abstract: An optoelectronic sensor is provided comprising an optics with focus adjustment, wherein the sensor has a movable carrier element having the optics and a fixed position holding element, and wherein the position of the movable carrier element is variable with respect to the holding element for an adjustment of a focal position. In this respect, at least one rolled leaf spring is arranged between the carrier element and the holding element.

Abstract: A camera for detecting an object in a detection zone is provided that has an image sensor for recording image data, a reception optics having a focus adjustment unit for setting a focal position, a distance sensor for measuring a distance value from the object, and a control and evaluation unit connected to the distance sensor and the focus adjustment unit to set a focal position in dependence on the distance value, and to determine a distance value with the distance sensor via a variable measurement duration that is predefined in dependence on a provisional distance value such that a measurement error of the distance value and thus, on a recording of image data of the object, a focus deviation of the set focal position from an ideal focal position remains small enough for a required image sharpness of the image data.

Abstract: A focus module for an optoelectronic sensor is provided that has a focus adjustable optics, a focus adjustment unit for varying a focal position of the optics, and a focus control to move the optics into a focal position corresponding to a distance value by means of the focus adjustment unit. The focus module here furthermore has a distance sensor for determining the distance value and the focus adjustment unit, the focus control, and the distance sensor are parts of the focus module.

Abstract: A camera for detecting an object moved through a detection zone is provided that has an image sensor for recording image data, a reception optics having a focus adjustment unit for setting a focal position, a distance sensor for measuring a distance value from the object, and a control and evaluation unit connected to the distance sensor and the focus adjustment unit to set a focal position in dependence on the distance value, and to trigger a recording of image data at a focal position at which there is a focus deviation from a focal position that is ideal in accordance with the measured distance value, with the focus deviation remaining small enough for a required image definition of the image data.
