ABSTRACT:
Several optical systems for imaging engines of imaging optical code readers are disclosed. Each optical system includes the abilities to change the depth of field of the imaging field and to adjust a focus quality of the imaging field. The disclosed structures for changing the depth of field of the disclosed optical systems allow for the automatic or manual selection of one of a plurality of depths of field.
