Abstract: A reader for and method of electro-optically reading symbols aim a front of a handheld housing at a symbol during reading. A solid-state, low resolution image sensor having a linear array of pixels is arranged in the housing and has less than 2000 pixels in number. The pixels sense return light returning along an optical path away from the symbol that is located in an extended range of working distances relative to the front of the housing. An imaging lens is positioned deep in the housing at an increased spacing of at least one inch as measured along the optical path away from the front of the housing, for capturing the return light over a reduced scan angle that is less than 40 degrees, and for projecting the captured light onto the sensor. A controller processes the return light sensed by the imager into data relating to the symbol.
