Abstract
An optoelectronic sensor comprising a light receiver, receiving optics in front of the light receiver, and a focus adjustment unit having an actuator and configured to move the light receiver, wherein the focus adjustment unit comprises a parallel guide having at least one flexible retaining element and moving the light receiver in a constant orientation on the optical axis of the receiving optics.
Claims18
An optoelectronic sensor comprising:
- a light receiver;
- receiving optics in front of the light receiver;
- and
- a focus adjustment unit having an actuator and configured to move the light receiver, wherein the focus adjustment unit comprises a parallel guide having at least one flexible retaining element and moving the light receiver in a constant orientation on an optical axis of the receiving optics,
- wherein the at least one flexible retaining element comprises a thermally-conductive layer, and
- wherein the at least one flexible retaining element further comprises two metal layers, the thermally-conductive layer being positioned therebetween.
3 more elements
A method for adjusting the focus of an optoelectronic sensor comprising a light receiver and receiving optics arranged in front of the light receiver, the method comprising:
- moving the light receiver by means of a focus adjustment unit using an actuator, wherein the focus adjustment unit moves the light receiver in constant orientation on an optical axis of the receiving optics by means of a parallel guide having at least one flexible retaining element,
- wherein the at least one flexible retaining element comprises a thermally-conductive layer, and
- wherein the at least one flexible retaining element further comprises two metal layers, the thermally-conductive layer being positioned therebetween.
