Scanners And Flatbed Scanners

Scanners are devices used for optically scanning images, text or handwriting and converting them it into digital image form. Scanners come in several forms. Their purposes also differ. Presently, several types of scanners are made to meet different needs. Barcode scanners, biometric scanners, card scanners, check scanners, film & slide scanners, photo scanners, sheet fed scanners, wide format scanners; flatbed scanners, high speed scanners and hand held scanners are the mostly seen scanner forms.

Flatbed scanners are used primarily in offices and are installed along with a computer. They can scan anything from text to pictures to graphics. Hand-held 3D scanners are mostly used in a variety of applications including industrial design, reverse engineering, gaming etc. Hand-held document scanners are pulled across the surface of the matter to be scanned.

The initial form of scanner was the drum scanner, which is no longer produced. The flatbed scanner is the mostly used scanner form in offices. The scanner comprises of a clear glass platen on which the sheet meant for scanning is kept. A bright xenon or cold cathode fluorescent light illuminates the pane from underneath. For scanning, the image is kept face downward and the opaque cover is shifted on it, so that light from outside sources cannot enter. However, images on transparent material cannot be scanned like this, but some better equipped flatbed scanners have provisions to illuminate the image from above too, which can scan such transparent images.
High speed scanners offer optical resolution and are costlier. However, their performance is unmatched. In sheet fed scanners, the input sheet is fed into the scanner through a horizontal or inclined route. They take little space and are ideal for workplaces facing space crunch. Large format optical scanners scans larger inputs and digitalizes them into a computable format. They are most suited to scan large drawings, architectural plans, maps and engineering drawings and graphs. They come in overhead or flatbed forms.

The market for scanners is hot these days, and so is the competition among manufacturers. The result is increased options and better services for the customer. Epson, HP, Nikon, Sony, Xerox, Canon, IBM, Kodak, Panasonic and several other manufacturers produce a wide range of scanners. Some scanners are incorporated into all-in-one printers too. Such scanners are mostly flatbeds.

There is no doubt that introduction of scanners has greatly helped our offices, services and shops alike. With all the choices available, buying a scanner is a cumbersome, but productive undertaking. Most scanners come in delectable colors and sizes. If you are running a small office, a small scale flat bed scanner would do, but larger corporate and other sectors may need wide screens or hand held ones to meet their requirements.
