Transparency adaptor
Flatbed scanners are designed to scan reflective material, but some accept an adaptor, often called a transparency hood, that has an integral fluorescent tube and is used to scan transparent materials. Some scanners are sold with the hood attached, others have it as an optional extra. These often allow up to A4 to be scanned but check, some of the budget options may only go up to 5x4in. A few scanners now have one built-in and use a tray that slides in and out of the unit. This avoids the need for the transparencies to come in contact with glass.
