    摘要： An optical reader in one embodiment can include a substrate defining an opening and solder pads coupled to the substrate proximate the opening. A laser diode including first, second, and third electrical leads can also be coupled to the substrate. First, second and third solder pads can be provided on the substrate and the first, second, and third electrical leads of the laser diode can be coupled to the first, second, and third solder pads. An optical reader in another embodiment can include a substrate having a first surface and a second surface. A laser diode assembly configured to emit a laser beam can be coupled to the first surface and an illumination assembly that can include light emitting diodes can be coupled to the second surface.

    摘要： Embodiments of the present invention comprise an indicia reading terminal including a focus element that extends the range of focus distances at which the indicia reading terminal can decode decodable indicia. In one embodiment, the focus element comprises a variable form element and a variable position element, the combination of which causes an image distance that can change in accordance with a separation distance between these two elements. The focus element can comprise an actuator, e.g., a piezoelectric actuator, which can be coupled to the variable position element in a manner that can cause the variable position element to deform the variable form element, and in one example, the deformation changes the focal length of the variable form element.

    摘要： An optical assembly for use with optoelectronic readers. An imaging optical assembly having an imaging optical axis forms an image of a two-dimensional region on an optoelectronic imaging device. An aiming pattern generator including at least a point-like aiming light source and an interferometric pattern generating optical element project onto the two-dimensional region a luminous aiming pattern that approximately coincides with the field of view of the imaging device. The aiming optical axis of the aiming pattern remains approximately coincident with the field of view of the imaging device over the range of reader-to-target distances over which the reader is used.
