ALE Technology

(Accuracy Lens Enhancement)

 

When looking at pixels across the range of a camera, the pixels tend to be more elliptical at the outside edges of the lens and more round in the middle. This anomaly, known as a spherical lens error, can introduce inaccuracies in the scanning system that can vary quite substantially between different points along the scan line.

 

GIS professionals and other specialized vertical markets involved in Quality Assurance and Verification require a very high grade of precision stability in the scanned image with a well-defined maximum deviation of 0.1% or less. Most scanner manufacturers typically state a +-0.1% accuracy between the two end-points of the scan line.

To help our customers improve scanning precision, Contex has developing Accuracy Lens Enhancement - a patented technology that sets new industry standards.

Accuracy Lens Enhancement (ALE)

ALE allows electronic correction of spherical errors in CCD-based camera-scanning systems.

ALE maintains precision across any two points of the scan line - exceeding even the most rigid requirements in the industry. Contex is the only scanner manufacturer to offer ALE technology for an entire range of scanners. 

How can I get it?

When you buy a new Contex scanner, you automatically get ALE technology - so you can start experiencing its benefits right away.
