An optical reader for reading a target having a bar code to be read, in which a unitary semiconductor device is mounted in a housing having an opening. The unitary semiconductive device includes a semiconductive substrate and a plurality of integrated components at the surface of the semiconductive device for generating and directing a light beam outward from the surface of the substrate sequentially along a plurality of paths through the opening of the housing. A detector is disposed in the housing for intercepting reflected components of the outward-directed light beam. In two implementations, the light beam is directed respectively by a single movable reflector or by a plurality of deformable mirror devices mounted on the substrate. The housing includes a grip, such a pistol grip, at an extremity offset from the opening.
