Example: An acquisition system has a 512 x 512 element, 10µm pixel pitch area scan
camera, a lens with an effective focal length of 45mm, and requires that 100µm in the
object space correspond to each pixel in the image sensor. Using the preceding equation,
the object distance must be 450mm (0.450m).

4.3 Compliance

The Piranha2 cameras have been designed for EMC compliance. The test setup has been
verified to the following EMC standards:
CISPR-22:1997
EN 50082-1:1997
EN 61000-4-2; ±6kV CD, ±8kV AD:1995
EN 61000-4-3; 3V/m:1996
EN 61000-4-4; 500V, 1100V:1995
Follow these specific guidelines to ensure best performance:
