Betterlight Scanback overhead scanning station:

Introduction:

Overview

The BetterLight Overhead scanning station is comprised of a large format viewcamera with a hi-res digital scanning back. The scanning style digital imaging is slightly slower than a capture style digital back, however the difference in speed is made up for with a higher amount megapixels.

Usage

The Betterlight scanback can be used for large format materials upwards of 40 to 50 inches, all the way down to very small materials like coins or stamps. Our scanning group relies on this scanner to take on all different types on materials. some materials that are scanned on this scanner are; newspapers, manuscripts, maps, photos, large format negatives (on a lightbox). Large collections with many objects that need scanning are completed much more rapidly with the scanback as apposed to a flatbed scanner.
