Many thanks to a reader for sending along a link to the Leica SCN400 I understand will be shown at ECP 2009 in Florence starting later this week. Details about the system are scant.
"The Leica SCN400 slide scanner makes work faster, more reliable, and flexible. Scanning and digitizing slides is accomplished in amazing speed. The system’s patented dynamic focus tracking enables the scanner to not only be faster, but reveal more of a specimen’s details. This can reduce the number of failed scans as compared to conventional focusing."
