TECHNICAL NOTE
Stability Ruggedization (r)
Like industrial ruggedized lenses, stability ruggedization protects the lens from
damage, but also ensures optical pointing and positioning is maintained after
shock and vibration. In addition to replacing the iris and a simplified focus
mechanism, individual lens elements are glued in place to prevent them from
moving within the housing. Figure 2 shows a stability ruggedized lens in which
the lens elements are glued in place and a clamping lock is used to simplify
the focus.
Lens elements sit within the inner bore of the barrel of an imaging assembly.
The space between the outer diameter of the lens and inner diameter of the
barrel is typically less than 50 microns. Despite the minimal amount of space,
decenters, on the order of tens of microns are enough to significantly affect the
pointing of the lens. When using a stability ruggedized lens, if an object point
is in the center of the FOV and falls on the exact center pixel, it will always fall
there even if the lens has been heavily vibrated. Stability ruggedization is important
in applications where the FOV must be calibrated, such as measurement
equipment, 3D stereo vision, lenses used for sensing in robotics, and lenses
used for tracking object locations. These applications often require the optical
pointing to be stabilized to values much smaller than a single pixel.

Industrial Ruggedization (i)
Industrial ruggedized lenses are designed to survive vibration and shock
without taking damage or changing focus or f/#. Flexibility is sacrificed by
eliminating moving parts to achieve this.
A standard fixed focal length lens uses a focus mechanism and an iris that
is comprised of thin leaves and ball detents to adjust f/# which can spring
out of place during shock and vibration. The iris is removed and replaced
with a fixed aperture stop in industrial ruggedized lenses and the focusing
mechanism, typically consisting of a focusing mechanism of a threaded
barrel within another threaded barrel, is replaced by a single thread and
rigid lock mechanism.
Industrial ruggedization is ideal for applications where the system will be
set up once and not Changed. An added cost advantage is also present
in this type of lens due to the removal of the complex movements and
adjustments, resulting in significant part reduction and cost savings. There
are more applications for industrial ruggedization, such as high vibration
factory environments, situations where the camera is rapidly accelerated,
inspection systems where many similar camera setups are repeated,
and robotic vision.
