Homogeneous Illumination of 1D and 2D Codes on Boxes at Varying Distances Thanks to Flat Dome Light
1D and 2D codes are used in large logistics centers to identify cardboard packaging. In order for these to have a high contrast and thus be read reliably, the codes must be evenly illuminated at all times and from varying distances. For this purpose, a flat dome light is installed on the side of the conveyor belt, with a code scanner positioned in the opening. This flat light illuminates the entire working range with homogeneous white light and enables reliable recognition of the codes on the shipping boxes.
