The TH7813 and TH7814 linear arrays are based on Atmel’s most recent know-how in
terms of design and technology. Flexibility and performance of these devices give the
opportunity to use them in most vision systems for industrial applications (web inspection, process control, sorting and inspection of various parts), document scanning up
to 200 dpi, metrology,etc.
