Integrated illumination assembly for symbology reader

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.

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.

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 comprising a first flat surface and a second flat surface different than the first flat surface, the first flat surface 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 flat surface adapted to allow a different portion of the light to pass through and out of the distal end to provide dark field illumination.

• an illumination source adapted to provide a light for transmission into the light transmitter;
• and
• the light transmitter distal end adapted to allow the light from within the light transmitter to pass through and out of the distal end to provide bright field illumination, and the light transmitter distal end being adapted to allow the light from within the light transmitter to pass through and out of the distal end to provide dark field illumination.

A method for providing bright field illumination and dark field illumination, the method comprising:

• providing a light transmitter arranged in a surrounding relationship to an interior area, the light transmitter having a proximal end and a distal end;
• providing an illumination source for providing a light for transmission into the light transmitter;
• allowing the light from within the light transmitter to pass through and out of the distal end for providing bright field illumination;
• and
• allowing the light from within the light transmitter to pass through and out of the distal end for providing dark field illumination.

A method comprising:

• providing a light transmitter and arranging the light transmitter in a surrounding relationship to an interior area, the light transmitter having a proximal end and a distal end;
• providing an illumination source and arranging the illumination source for providing a light for transmission into the light transmitter;
• and
• using a first portion and a second portion of the light transmitter distal end, the first portion allowing a portion of the light from within the light transmitter to pass through and out of the distal end for providing bright field illumination, and the second portion internally reflecting and redirecting a different portion of the light to exit near the distal end for providing dark field illumination.
