An optical encoder comprises an emitter; a receiver; a reflector; and a code carrier, wherein the emitter emits electromagnetic radiation along an emission axis in the direction of the reflector and the reflector deflects the electromagnetic radiation along a reception axis in the direction of the receiver. The code carrier is movably supported and has a sequence of code sections to interrupt or to give way for the emitted electromagnetic radiation to impinge on the detector in dependence on the position of the code carrier, wherein the emission axis and the reception axis extend at an alignment angle with respect to one another that has a value in the range from 30 degrees to 150 degrees.

Optical encoder

An optoelectronic apparatus is provided having a carrier device that has at least one optoelectronic transmitter and/or at least one optoelectronic receiver at an upper side; at least one first optical element, a second optical element, and a third optical element that are arranged in a layer arrangement above the carrier device, with the second optical element being arranged above the first optical element and the third optical element being arranged above the second optical element, and with each of the at least three optical elements comprising a lens element, an aperture element or a filter element; and a holding device that holds at least the first optical element and the second optical element relative to the carrier device and partly surrounds them, with the holding device furthermore either holding the third optical element relative to the carrier device and partly surrounding the third optical element or forming the third optical element.

Optoelectronic apparatus, carrier device, optoelectronic transmitter and optoelectronic receiver

An optoelectronic apparatus is provided having a carrier device that has at least one optoelectronic transmitter and/or at least one optoelectronic receiver at an upper side; having a lens element that is provided above the carrier device and that has at least one lens section for the at least one optoelectronic transmitter and/or for the at least one optoelectronic receiver; and having a holding device that at least partly surrounds the carrier device and the lens element. The lens element has a mechanical coding section that projects out of the holding device and that enables at least one coding element for identifying the optoelectronic apparatus.

Optoelectronic apparatus having a coding element

An optoelectronic apparatus is provided, comprising a carrier device that has a longitudinal extent and a transverse extent, wherein the carrier device has a plurality of electrically conductive tracks aligned in parallel with the longitudinal extent, and wherein the carrier device has a plurality of contact chambers aligned in parallel with the transverse extent at an upper side. Each of the contact tracks is electrically contactable in each contact chamber to be able to install at least one optoelectronic transmitter and/or at least one optoelectronic receiver in a variable mounting in the respective chamber.

Optoelectronic apparatus

An optoelectronic apparatus is provided that has at least one optoelectronic transmitter and at least one optoelectronic receiver. The optoelectronic apparatus furthermore has a storage device having at least one non-volatile memory that is adapted to store an individual data set. A data interface is furthermore provided that is adapted to at least partly read the individual data set out of the non-volatile memory of the storage device.

In one example, a drop detector includes a light source for illuminating drops passing through a drop zone, multiple light detectors near the light source for detecting light scattered off drops passing through the drop zone, and multiple lenses each configured to focus light from the drop zone on one of the light detectors. In one example, each light detector is arranged in the same plane with all of the other light detectors. In one example, the lenses are configured to focus light from two different spaces in the drop zone on different detectors or groups of detectors. In one example, the lenses are configured to focus light from a single space in the drop zone on multiple detectors.
