Performance
High stability and measurement accuracy are achieved
with the newly developed optical system
Multi-Wavelength Laser + I-DSP
With conventional lasers, the transmission spot produces a patchy pattern
(as shown in the figure to the right). This is a laser-specific interference
problem caused by the laser having a single wavelength. The IG Series
sensor overcomes this problem by using a multi-wavelength laser. Because
shadows are formed on the CCD more clearly, the sensor remains highly
stable, even with targets that are conventionally
difficult to detect (e.g. transparent objects).
With the I-DSP (a parallel computing chip)
incorporated in the receiver, the sensor can
perform data processing at high speed,
reducing noise to a minimum.
SPOT IMAGE
Single-wavelength laser
(conventional laser sensor)
A patchy pattern appears.
Due to the multi-wavelength
laser used, the beam
pattern has a more uniform
intensity distribution.
Repeatability of 5 μm

STABLE DETECTION OF TRANSPARENT
& MESH TARGETS
The L-CCD makes it possible to detect a target based on
its position. Edge control and positioning of transparent and
mesh targets can be performed stably.

THREE CONCEPTS
The intelligent I-Series consists of a high-accuracy sensor lineup that realizes low-cost
high performance with only the most advanced functions for on-site operations.
High accuracy was achieved by using the technology
and functions developed for high-accuracy
measuring instruments.
Developed for use in harsh environments, the IG Series
was designed with a strong structure.
Excellent usability makes it possible to quickly and
easily perform stable measurements without any
difficult adjustments and settings.
