Description
This smarter C2 is the perfect alternative for users looking for a cost-effective color
linescan camera. The Aviiva SC2 takes advantage of all the features that made the
success of the Aviiva family: accuracy, versatility and easy implementation:
•
Flat-field correction and contrast expansion functions.
•
Embedded white balance and color space correction.
•
A very compact mechanical design that incorporates a 4k color linear sensor.
•
Atmel manages the entire manufacturing process from the sensor to the camera.
The result is a camera able to operate in 8, 10 or 12 bits with dedicated
electronics offering an excellent signal-to-noise ratio.
•
Programmable settings let the user work at different integration times, gains and
offsets. The external clock and trigger allow synchronization of several cameras.
Applications
The performance and reliability of this camera make it suitable for machine vision
applications requiring low-cost color capture. Such applications can include print,
packaging inspection or part sorting. With this camera, one avoids the usual problems
observed with tri-linear sensors on optical alignment and object synchronization.
