Flatbed Scanner
A flatbed scanner is a device that digitizes documents, photos, or objects. It captures high-resolution images to create digital copies. It features a flat, glass surface where the item to be scanned is placed, and a light source and sensor move beneath the glass to create a digital copy. A flatbed scanner stays still, unlike document feeders that pull paper through. This makes it perfect for delicate, bound, or oddly shaped items.
How a Flatbed Scanner Works
- Placing the Item: Lay the document, photo, or object face-down on the scanner's glass bed.
- Light & Sensor Movement: A bright light, like LED or fluorescent, shines on the item. An image sensor, like a CCD (Charge-Coupled Device) or CIS (Contact Image Sensor), moves over the surface to capture details.
- Image Processing: Scanned data turns into a digital file. You can save it in formats like JPEG, PNG, PDF, or TIFF.
- Editing & Storage: Users can adjust brightness, contrast, and resolution before saving or sharing the file.
Benefits of a Flatbed Scanner
- High-Quality Scanning: Provides detailed and accurate scans, especially for photographs and artwork.
- Versatility: It can scan single sheets, books, passports, artwork, and 3D objects such as coins or jewellery.
- No Paper Jams: Flatbed scanners don’t use rollers to feed sheets. This lowers the chance of damage compared to document feeders.
- Handles Delicate & Thick Items: Great for fragile papers, old photos, and materials that can't be bent or rolled.
Flatbed scanners are widely used in homes, offices, libraries, and professional studios due to their ability to produce sharp, high-resolution images while accommodating a wide range of materials.
