Laser Surface Mapping - Surface Inspection Solution

QUEST produces a variety of laser probes that can be inserted up to 100
feet inside tube to map the inside surface. As the probe is drawn through the tube, the measuring head on the end of
the probe rotates and can collect several thousand radius measurements per probe rotation. The helical pattern of radius
data is analyzed to detect a wide variety of flaws or compute geometrical features such as diameter and ovality.
The probes can be articulated to go around bends. The probes do not
have to be centered in the tube for proper operation, however centering mechanisms are used to keep the rotating measuring
heads from contacting the ID surface of the tube.
QUEST has a variety probes that operate in as small as 0.5 inch ID to as
large as 6 inch ID.

The following probe is an example of a non-rotating laser head for quality control applications
that integrates 12 individual laser gauges into a single compact measurement head less than 0.25 inches in diameter. This
probe head and associated system was originally developed for the nuclear Navy. Several systems have been fielded for
quality control and testing of steam generator tubing.

The following probes are used in our quality control equipment for laser mapping of small parts
and hose ends. These probes are ideal for non-contact measurement in areas that are difficult to access. The probes
vary in diameter from 4 mm to 10 mm with measuring ranges from 3.2 to 7 mm.
