Optical apparatus for an optoelectronic sensor

An optical apparatus (10) for an optoelectronic sensor (100, 200) which has at least one lens (14a-b), wherein a further optical element (18) is provided in the beam path of the optical apparatus (10) for extending the depth of field, wherein the optical element (18) has a first planoparallel zone (22a) and a second planoparallel zone (22b), with the first planoparallel zone (22a) and the second planoparallel zone (22b) each only covering a part of the beam path of the optical apparatus (10) and thus generating a first depth of field and a second depth of field.

An optoelectronic sensor (100, 200) having a light receiver (16) with which an optical apparatus (10) is associated, the optical apparatus (10) having at least one lens (14a-b), wherein a further optical element (18) is provided in the beam path of the optical apparatus (10) for extending the depth of field, wherein the optical element (18) is made and/or arranged such that a part of the beam path remains free and thus generates a first depth of field;

• and wherein the optical element (18) has a planoparallel zone which only covers a part of the beam path of the optical apparatus (10) and thus generates a second depth of field.

An optoelectronic sensor (100, 200) having a light transmitter (202) with which an optical apparatus (10) is associated, the optical apparatus (10) having at least one lens (14a-b), wherein a further optical element (18) is provided in the beam path of the optical apparatus (10) for extending the depth of field, wherein the optical element (18) is made and/or arranged such that a part of the beam path remains free and thus generates a first depth of field;

• and wherein the optical element (18) has a planoparallel zone which only covers a part of the beam path of the optical apparatus (10) and thus generates a second depth of field.
