Barcode reading and verification and machine vision
Barcode reading - 1D/2D Symbols
1D or linear barcodes are the most common symbologies used for automatic identification although increasing numbers of manufacturers are using two-dimensional (2D) symbols, such as Data Matrix, that offer greater placement flexibility and increased data capacity.
Machine-readable symbols generally fall into the categories of linear barcodes, stacked symbols, 2D symbols and Optical Character Recognition (OCR) fonts.
Omron Microscan provides fast, reliable reading solutions for all symbologies and OCR and canread any linear barcodes or 2D symbols printed or marked by any means, and verify them to industry standards.
Direct part marks
Direct part marks (DPM) are typically 2D Data Matrix symbols permanently marked by such methods as dot peen or laser/chemical etch onto substrates including metal, plastic, rubber or glass. Omron Microscan offers a comprehensive family of readers and verifiers with illumination and decode algorithms specifically designed for difficult direct part marks.
The barcodes and legible and precise texts have a great importance regarding productivity. Inconsistencies in quality can lead to process inefficiencies and downtime. Unreadable barcodes may require re-labeling, re-scanning, or even manual entry of critical information by a human operator.
Omron Microscan barcode verifiers are embedded off-line or inline solutions that include camera, software, and precision illumination specifically designed for the verification of 1D/2D codes and direct part marks to ISO/IEC standards.
Without verification, when a bad barcode is identified, thousands of poor-quality barcodes may have already escaped down the line. With verification, bad barcodes are prevented from being applied to the product, eliminating the chance for future failures.
Machine vision inspection
100% quality control in manufacturing reduces costs and ensures a high level of customer satisfaction. With its wide range of capabilities and applications, machine vision is becoming the standard discipline for automating inspection and other modern industrial processes, through complex image capture and analysis.
Omron Microscan machine vision systems use a variety of advanced hardware and software components to perform inspection tasks at high speeds with greater precision.

Integrated autofocus technology with liquid lens
Built-in MicroHAWK models, this technology uses electrostatic pressure to create electrical currents that react with the two liquids inside the lens to produce the appropriate lens curvature, optimizing the image capture system and providing an almost infinite range of work in autofocus applications, this enables barcode imagers to read symbols at any distance and speed in any environment.
Omron Microscan integrates its liquid lens technology into its highest performance imaging platforms rather than requiring add-on optical accessories, reducing costs, maintenance, device size, and integration complexity.
Without mechanical parts
Read range: 50mm-300mm
Focus change response time: 70ms
Optimal Lighting for identification and verification systems
Proper lighting is critical to the success of a machine vision application. A well-planned lighting solution will result in better system performance saving time, and therefore, increasing productivity.
With a broad range of wavelength (color), field of view (size), and geometry (shape) options available, Omron Microscan innovative NERLITE line of products, allows machine vision systems and automatic ID to work with greater precision and maximum performance.
With this technology it maximizes feature contrast while minimizing contrast of everything else, thereby allowing the camera to clearly "see" the part or mark required.
