Painted object and black rubber
Inclined transparent object or glossy object
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 significantly 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.
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.

Reproducing a clear, stable profile is difficult for

amount of laser reflection and reflection angle differ
according to the positions of different materials on
such objects. To solve the problem, Omron’s unique
“multi-sensitivity function”has been improved.
The measurement speed for the function has been
increased so that the function can be used in

2 Dimensional Measurement
Powerful functionality in a compact design
A light-cutting method is used. The widely-spread laser beam is projected on the
measurement object to measure its cross-sectional shape.
The business card sized ZG2 controller incorporates a built in LCD monitor for
profile visualization. The LCD display also gives access to the ZG2's intuitive and
simple to use setup screens.
The controller also includes a USB and RS-232 interface for easy connectivity.
Measurement principle
A band-like laser beam is projected on the measurement object, and the reflection
from the object is received by the CCD. A shape profile of the measurement
object is formed based on the principle of triangular distance measurement.
Since 2D data of the X and Z axes are measured simultaneously, there is no need
to move either the sensor or measurement object.
Measurement conditions
are indicated by
easy-to-understand icons.
Since three CCD modes are available; high-speed mode, standard mode, and high-precision
mode, the ZG2 can be used for processes that require high speed or inspections that require
higher precision. The measurement center distance remains fixed even when the mode is
changed so the sensor head position does not need to be adjusted.

A feature of 2D measurement sensors is projecting a wide
beam onto an object to be measured in order to simultaneously
check dimensions such as the width and gap. However, since
light reflects differently according to the material, color, and shape
of an object’s surface, experience and skill are required to obtain the
most adequate profile which is a prerequisite of high-precision measurement. As a
result, measurement sometimes takes a long time. The ZG2 has an“APS
function”developed by combining a variety of techniques for obtaining profiles. An
optimal profile with no lost part can be obtained with the simple push of a button,
even from black objects, and also in conditions with ambient light where
adjustment was difficult using conventional sensors. Optimal tuning is simple and
easy so startup work time can be significantly reduced.
Mounted on the ZG2-WDS3VT
The new gauss lens was born out of Omron’s passion for sensing technology.
In the lens, a coupling lens structure including an aspherical lens is used, which
allows for clear, bright images with low aberration, even though it is a wide-angle
lens. Previous lens designs could not receive sufficient light reflection when
objects were inclined. Using the new TAGG lens design, light reflection can be
received at angles up to ±5°
. The lens shows excellent performance for stable
measurement of mirror and gloss surfaces with large amounts of regular reflection
components and also transparent objects such as glass.

Utilizing its unique optical filter technology, Omron has developed a new optical
system where ambient light components are effectively removed so that only
necessary reflection components from the object can be received. A control
system is also used in which the laser exposure period and the CCD receiving
period are synchronized. The combined effect of these has achieved ambient
illumination resistence of 7,000 lx, seven times higher than conventional models.
Measurement can be performed at a stable level without being influenced by
fluorescent light or other surrounding conditions.

Light reflected from
these parts do not

Omron's unique "multi-sensitivity function" is used to measure complex shapes by
varying the intensity of the laser light over different areas of reflectivity across the
object. The function has been further improved in the ZG2 Series. The optimal
profile is formed according to the reflection of the object approximately two to ten
times faster than in former models. The ZG2 can now perform measurements on
higher-speed takt-time lines.
Principle
While switching sensitivity levels for
workpieces of which reflectivity varies from

longer for multi-sensitivity, high-speed multi-sensitivity, or other settings. When the high-power
mode is ON, the shortest image input period is 95 ms regardless of the setting of the CCD mode.
Use the eco monitor in the RUN mode to determine the actual image input period.
Note : 1. The controller link unit is necessary for linking.
Note : 2. Data is saved in the memory of the main unit during logging. The data is automatically saved
in a memory card after logging is completed.The maximum number of logging differs according to
set conditions. For details, refer to the Users Manual.
Note : 3. Measurement values for 65,000 measurements can be saved even when two sensor controllers
are connected and each performs eight tasks.
Note : 4. The value is the maximum number achieved in the following conditions.
One sensor controller performs one measurement task.
