INTRODUCTION
Starrett’s Automatic Vision (AV)
metrology systems with M3 software combine precision
mechanics, video edge detection (VED), powerful vision metrology software, and motorized
operation under computer control. Operation can be under full computer numerical control (CNC)
for large runs, or manual for individual measurements or short runs with inputs from a pendant
with a joystick and trackball. These systems have proven themselves in quality assurance,
inspection labs, manufacturing assembly, and research facilities worldwide.
AV300 systems
feature a 513 x 275 mm (20.2” x 10.8”) stage, 300 x 150 x 135 mm (12” x 6”
x 5.5”) of CNC XYZ travel. These systems are available as a benchtop system or with an
ergonomic workstation that supports the system’s metrology unit, 24” touch screen monitor and
PC, wireless keyboard, and wireless mouse.
AV350 and AV450 systems
come standard with a machine pedestal, which supports the metro-
logy unit on a solid granite base, and a separate computer cart, which supports the system’s
touch screen monitor, wireless keyboard, and wireless mouse, and 12:1 motorized zoom optics.
Both systems feature the same 716 x 549 mm (28.2” x 21.6”) stage. AV350 systems provide 350
x 350 x 200 mm (14” x 14” x 8”) of CNC XYZ travel, while AV450 provide 450 x 350 x 200 mm
(18” x 14” x 8”) of CNC XYZ travel.
Video Imaging,
as ordered, can be provided by a 1.3 Mpixel color CCD camera with factory
installed 6.5:1 or 12:1 zoom optics, or by a 2 Mpixel color video camera with a bayonet lens mount
which accepts a 6.5:1 motorized zoom optics or any of six available fixed-magnification telecentric
lenses (0.30X, 0.50X, 0.80X, 1.0X, 2.0X, 4.0X).
Illumination
can be provided by ultra-bright, long-life LEDs, or by quartz halogen lamps with
fiber-optic light delivery, as ordered. Two-channel illumination includes a ring light for surface
illumination and a back-light for silhouette illumination. Three-channel illumination adds surface
illumination that is coaxial with the camera lens. The standard LED ring light can be replaced by
a Quad Dark Field (QDF option) ring light, where the LED intensity is individually adjustable in
four quadrants. The height of the QDF ring light is adjustable on a motorized CNC Z-track for
shadow control.
A touch-probe
is optional and is integrated with the 3D version of MetLogix M3 CNC software.
The touch probe allows the measurement of tilted, tapered and vertical surfaces which could not
be measured with video edged detection alone.
System control
is provided by a MetLogix M3 CNC Controller and a computer which runs Met-
Logix M3-VED-CNC software under Windows 7 Professional. Programmable features include
X-Y-Z motion, optical zoom, 2- or 3-channel illumination, 2D (X-Y) geometrical constructs for
VED systems, and 3D geometrical constructs for VED systems with the optional touch-probe.
M3 software is described in a separate manual by MetLogix. The AV300, AV350 and AV450
systems utilize a separate 24” touch-screen monitor and PC as the primary operator interface.
Options
include auxiliary lenses for the zoom optics (0.5X, 1.5X, 2.0X), a choice of NIST-
traceable calibration standards, and an ergonomic workstation.

please see the next page. Due to continual product improvement,
specifications may change without notice.
CAUTION:
Exceeding the system’s rated load capacity will reduce accuracy and may
damage the mechanical structure.
