Description
of LS Laser Systems Model 150 Ceramic Scriber
1.
CO2-Laser
The
beam source is a sealed off CO2-Laser. The output power
can be adjusted continuously to meet the requirements
of the application. Due to its design, this laser has
no consumable parts that need regular replacement.

Focusing Optics
The
focussing optics with beam expander is fix mounted on
the laser rail.
The
laser beam is guided via an adjustable mirror to the
focussing lens.
The
optimal focus can be adjusted by focus mounting.
A
beam expansion (Galilean-principal) gives a small focal
spot with a good depth of focus.

System Concept
The LS-150 is
a laser scribing system
The laser unit
with focusing optics is mounted on a precision linear
guidance. The focus distance
can
be fine adjusted by a micrometer screw (standard).
Laser, deflection
unit with a camera and workstation are enclosed in a
protective housing.
The whole front side of the working area
can be opened in the manual mode.
The system concept is prepared to adapt
an automatic loading system.
The workstation
is accessible via a slide at the front of the machine.
This slide is provided with an interlock-switch, which
interrupts the laser beam via a safety-shutter when
it is opened.
The circuits are held by mechanical clamps,
The standard holder is constructed up to 4"x4".
The complete system is based and mounted
on a profile frame. Within this profile frame the personal
computer, laser power supply, and motor control are
mounted.
There is an internal exhaust jig to remove
dust to an external port.
The
complete system corresponds according to DIN EN 60825/VDE
0837 respectively VGB 93 to laser safety-class 1.
