Abstract
An optical system used in a barcode scanner is disclosed to include a standing cylinder lens, a light source that emits a light beam through the standing cylinder lens onto the barcode of the product to be scanned, a focusing lens that focuses the image reflected by the barcode, a linear sensor array, and a slanted arranged reflector that reflects the image focused by the focusing lens onto the linear sensor array for reading. The light path of the image focused by the focusing lens onto the reflector and the light path of the image reflected by the reflector onto the linear sensor array are overlapped, forming a light path overlap region.
