Claim 0:
1. An illuminator, comprising:
a light pipe with an open frame structure for visual aiming of the illuminator to facilitate an alignment of a barcode, wherein chamfered inner edges of the light pipe are textured and are located on a front opening of the light pipe to allow an emission of dark field illuminations in different orientations;
a circuit board, attached to a back opening of the light pipe, comprising at least one of one or more dark field LEDs for generating dark field illuminations and one or more bright field LEDs for generating bright field illuminations, wherein a camera is mounted on the circuit board, through an opening on the circuit board, with a lens of the camera, viewing at a front opening of the light pipe; and
wherein, the one or more bright field LEDs produce one or more alternating point sources for providing bright field illuminations in different directions to minimize a specular reflection hot spot without using any diffuser during the bright field illuminations.
