The MD-V9900A Series is equipped with the newly developed DEPC
(Dual End Pumping Cavity).
The DEPC significantly improves the optical exchange efficiency compared to that of a traditional end pumping system. This higher efficiency means that the diode has to use less current to generate the equivalent power, reducing energy consumption and increasing diode life.
The MD-V utilizes an end-pumping YV04 laser system that generates
an ideal laser beam. Conventional systems are forced to employ a
multi-mode laser, leading to fluctuations in laser power and target
Single mode laser's concentrate the beam to provide high quality marking on a wide range of surfaces.
The MD-V9900A Series employs a Q switch frequency more than double
that of previous KEYENCE lasers.
The high frequency enables smooth marking of fine resolutions on high speed productions lines.
Both continuous wave and pulse oscillation are available to accommodate varying surface conditions
The 3-Axis laser control (X, Y and Z axes) sets the maximum spot
position at any focal length.
The focal length can be set within a 42-mm range without attenuating the flatness of the marking area.
Varying the spot size of the laser is helpful when trying to
enhance the contrast of characters on specific materials, or
engrave more deeply into the target surface.
Typical defocus techniques may cause varying character size and position, while the MD-V can provide uniform quality of characters.
Marking in a large area often requires moving a target workpiece
using an X-Y stage, or switching the lens on a conventional laser
to create a wide marking area.
Using an X-Y stage increases integration costs and time, and also decreases product throughput. A wide area lens can help these problems, however characters are often displaced or blurred at the edge of the marking area.
The MD-V9900A Series utilizes a special lens system along with its unique 3-axis control to create a highly accurate 300 x 300-mm wide marking area, eliminating the need for mechanical adjustment while maintaining character integrity.
The MD-V9900A Series features 3-Axis control to modify the laser
position according to the shape of a target, which can include
steps, inclined surfaces, cylinders or circular cones.
The MD-V9900A Series minimizes distorted, worn or chipped characters while enabling uniform marking on a wide variety of shapes.
