Integrated Illumination Assembly for Symbology Reader
First Claim
1. An illumination assembly for a mark reader comprising:
- a light transmitter arranged in a surrounding relationship to an interior area, the light transmitter having a proximal end and a distal end;
an illumination source adapted to provide a light for transmission into the light transmitter; and
the light transmitter distal end including a first portion and a second portion, the first portion being adapted to allow a portion of the light from within the light transmitter to pass through and out of the distal end to provide bright field illumination, and the second portion being adapted to internally reflect and redirect a different portion of the light to exit the distal end to provide dark field illumination.

Abstract
Systems and methods provide an illumination assembly for a mark reader. A light transmitter is arranged in a surrounding relationship to an interior area, with the light transmitter having a proximal end and a distal end. An illumination source provides a light for transmission into the light transmitter. The light transmitter distal end allows the light from within the light transmitter to pass through and out of the distal end to provide bright field illumination and dark field illumination. The light transmitter distal end may include a first portion and a second portion, where light from within the light transmitter passes through and out of the first portion to provide bright field illumination, and light from within the light transmitter passes through and out of the second portion to provide dark field illumination.

10. A light transmitting assembly for illuminating a mark that is imaged by an image sensor, the light transmitting assembly comprising:
-
a light transmitter arranged in a surrounding relationship to an interior area, the light transmitter having a proximal end and a distal end; an illumination source adapted to provide a light for transmission into the light transmitter; and the light transmitter distal end including a chamfered surface and a diffusive surface, the diffusive surface being adapted to allow a first portion of the light from within the light transmitter to pass through and out of the diffusive surface to provide bright field illumination, and the chamfered surface being adapted to internally reflect and redirect a second portion of the light so the second portion of the light exits the distal end to provide dark field illumination. - View Dependent Claims (11, 12, 13, 14, 15)

16. An illumination assembly for a mark reader comprising:
-
a light transmitter arranged in a surrounding relationship to an interior area, the light transmitter having an internal wall, an external wall, a proximal end, and a distal end; an illumination source adapted to provide a light for transmission into the light transmitter; and the light transmitter distal end adapted to allow at least a portion of the light from within the light transmitter to pass through and out of the distal end to provide bright field illumination, and the distal end being adapted to internally reflect and redirect a different portion of the light so the different portion of the light exits the interior wall to provide dark field illumination. - View Dependent Claims (17)
