Power sensors series PM200 / PM100
Power regulation directly at the point of processing
The power sensor PM200 / PM100 takes measurements
directly at the processing point. It measures power, the
momentary temperature and, by providing feedback to
the laser-diode controller, it enables precise control of
the current for constant processing performance.
 Regular (PM200) or continual (PM100) monitoring of
laser power in combination with the CS400 series
 Automatic adjustment of laser current for regulation of
processing performance
 Storage of all parameters directly in the power sensor;
no PC required
 Direct measurement at the point of processing or
online via beam splitter

* CW power is quoted for a maximum irradiation of 2 minutes. In combination with a series CS 400 laser diode controller, irradiation is automatically interrupted after a maximum of 15 seconds.
** Maximum power depends on the overall optical design (beam splitters, neutral density filters)
Pyrometer series SE200 / SE400
Process regulation with digital precision
The heart of the pyrometer series is the laser-head interface that provides the connection to the Amtron controller and also four interfaces for connecting sensors,
laser-head components and pilot lasers. This level of integration allows process regulation, control and regulation functions and the 24-V power supply to be realized
via a single cable. New is the SE400 series with enhanced
features.
 Regulation of processing temperature
 Output laser power monitoring
 Control of components such as shutters or warning
lights
 Power supply, control and regulation over one central
cable

Process controller CU190
Regulation and control of laser processing
The process controller CU190 stands out with its fast power modulation, which makes it ideal for regulating and
controlling the processes between the system and the
laser. The device offers a range of connections via different fieldbus systems. The process controller uses various input parameters such as feedrate, external sensors
or trigger/gate to calculate and control the analog and
digital laser power. The control unit modulates the amplitude, pulse width, or frequencies with fast cycle times
of 1µs. In contrast to conventional system controllers, the
CU190 process controller offers fully customizable laser
control, which easily integrates into existing processes.
