Painted object and black rubber
Dark colored materials or materials with a matt finish, like black rubber often do not reflect sufficient light to maintain
a stable measurement. They are also susceptible to the influences of ambient light so are difficult to measure using
conventional laser measurement sensors. The ZG2 solves these problems because it is supersensitive and signifi-
cantly reduces ambient noise. It also has an APS function to automatically tune parameters such as a receiver’
s
sensitivity and background suppression level at optimal levels according to the ambient light conditions. Shape
profiles can also be easily reproduced at optimal conditions to achieve high precision measurement.
Measurement of moving objects is possible because measurement can be performed within a short exposure time.

inclination tolerance
Inclined transparent object or glossy object
On an object with strong regular reflection components such as luster sides and transparent objects, the amount of
light reflection significantly reduces when the object is slightly inclined, lowering measurement stability. The sensor
head ZG2-WDS3VT with a high-performance gauss lens is the solution for the problem. Its inclination acceptance
range has been increased to
2.5
times as compared to conventional models so transparent objects can be measured
up to a
±
5
°
inclination at a stable level. Because the ZG2 has this function, it is useful for assembly inspections for
lenses and glass plates.

Assembly inspection of electronic parts
The ZG2 can measure parts with glass or a glossy object
such as CCDs, CMOSs, and crystal splinters of quartz
resonators at a stable level. It can be used for assembly
inspections of parts because it can measure steps on a
substrate or package side.
Assembly inspection of lenses
The ZG2 can measure the step between the
peak of a lens and lens holder to check if they
are assembled properly.

High-speed takt-time line
Reproducing a clear, stable profile is difficult for
objects with both black and metal sides, cylindrical
objects, and complex-shaped objects because the
amount of laser reflection and reflection angle differ
according to the positions of different materials on
such objects. To solve the problem, Omron’ unique
s
“multi-sensitivity
function”
has been improved.
The measurement speed for the function has been
increased so that the function can be used in
high-speed takt-time lines.
