Sick Inc. has unveiled its CLV650 bar-code scanner with autofocus technology and the CLV640 with dynamic focus. The 1-D scanners use the company’s modular advanced recognition technology (SMART) code reconstruction algorithms and microprocessors to read damaged and dirty bar codes. The 650 model is suitable for use in applications where space is limited and a large depth of field is required. The 640 reads high-density codes and provides an increased depth of field in applications that require an external input to change the focus position. Proprietary Sopas software reduces programming and processing requirements of the host system.
