Application of optics in barcode scanners

Jul. 17, 2020

With the development of age of the information, QR codes and bar codes are more and more widely used. People use two-dimensional codes and bar codes to store or extract information. So bar code scanners are widely used. With years of experience and production knowledge, CLZ Precision Optics Co., Ltd. provides customers with custom optical components made of various optical materials, including optical lenses, optical domes, optical windows, optical reflectors, and optical prisms.

The bar code scanner is an electronic device for reading the information of bar code and QR code. It is usually composed of light source, optical lens, optical sensor and circuit module. Bar code scanners use optical components to collect optical signals, and photoelectric components convert the detected optical signals into electrical signals. The electrical signals transmit the collected information to the calculation through a digital converter for processing.

The optical elements that can be used in a barcode scanner are optical lenses, rotating prisms, and optical mirrors. Optical lenses are used to gather light and collect optical signals. Rotating prisms are used to scan the light beam. Plane mirrors are used to change the optical path to realize multidirectional scanning light. In this way, bar code scanners can improve the integrity of the scanning pattern and reduce the harm of laser radiation.

Bar code scanners can be used for laboratory management and teaching, to improve the efficiency of the management and use of instruments, reagents, and samples in the laboratory to avoid serious consequences due to confusion of chemical reagents. Secondly, barcode scanners can be used in micro-library systems to realize library self-borrowing, recommendation and access to books. Bar code scanners can also be used for daily necessities packaging, electronic ticketing, movie tickets and identification.
