Flatbed scanners are used to convert analog images into digital files. They consist of a platen or glass pane that covers a light source underneath (either cold cathode fluorescent or xenon). A CIS or CCD optical array moves along the hard copy placed on top of the platen. They are commonly used to digitize photos, handwriting, and objects.
Standard flatbed scanners connect to computers using USB ports or other interfaces. They scan in monochrome and color. They can have bit depths of as high as 58 bits to produce excellent image detail.
Wireless flatbed scanners
Wireless flatbed scanners can connect to several computers using wireless LAN or Bluetooth. They have built-in document feeders that ensure straight and even scanning. They scan in monochrome and color.
