The efficient Bookeye 4 V3 digitizes source material such as bound documents at high speeds in up to 400 dpi optical resolution and formats up to DIN A3. Over 17 years of electronic, optical and mechanical engineering experience went into the creation and manufacture of the Bookeye 4 models. The clever mirror mechanism captures the document precisely from edge to edge, whether it is a flat document or a book open at an angle of 120 degrees. The V-shaped book cradle was optimized to reduce the risk of damage to book spines and binding during digitization. The book cradle holds the open book at an angle of 120 degrees; enough to effectively scan the contents of a page, while gently preserving the original subject matter.
