摘要 |
The invention is optical assembly for use in a barcode reader that includes a frame having a rear housing and a pair of arms outwardly extended from the housing. An optical card containing an imaging lens is slidably received in a rear guideway situated between the arms. An aperture card is slidably received in a front guideway situated between the arms in front of the lens. Lamp support brackets are also mounted to either side of the arms. Each bracket contains a pair of LEDs that are aligned in coplanar relation with the imaging lens. A cylindrical lens is mounted in front of the lamp support brackets within the arms of the frame to magnify and focus the illumination from the LED upon a target in barcode space.
