Plustek's patent pending SEE™ (Shadow Elimination Element) Technology includes a specially designed edge and lamp. This technology allows for "zero edge" scanning which means the scanning module can scan right up to the edge of the scanner where the book spine is placed. The book can therefore be scanned with the pages completely flat on the glass to avoid the annoying book spine shadow and distorted lines of text which occur when the books are scanned on a traditional flatbed scanner.

Plustek has already received a patent on its specially designed lamp with curved ends. This lamp allows the correct amount of light for a good scanned image at both ends of the scanning module.
