2.5 Centering the Beam in the Tip

Orifice Using the Beam
Centering Camera

Beam centering in the tip orifice is
essential to any laser process. It is
the customer’s responsibility to
center the laser beam in the tip
orifice.

If desired, it is possible to perform this
procedure manually. In that case, see

Section 2.6

The beam MUST be centered in the gas
jet tip.



Check beam alignment:

During initial installation.

After replacing the fiber.

After replacing the collimator
optics.

After replacing the focus lens.

Laser Mechanisms’ beam centering
camera (PLFXT0269) is used for tip
centering.



It shows the position of the red aiming
beam in the orifice of the gas jet tip.



The beam centering camera requires
a Windows computer with a USB port
and Plugable 250X Digital USB
Microscope software or equivalent.

1. Download and install the latest version

of Plugable 250X Digital USB
Microscope software to the
appropriate computer.

http://www.lasermech.com/productupdates



The Plugable.com website also
has the software available to
download and videos with more
details on the features and uses of
the microscope.

2. Verify the high power beam is

disabled.

3. Install a gas jet tip with a 2 mm or

larger orifice. See

Section 5.2

for

more details.

4. Turn on the red aiming beam from the

fiber laser.

5. Connect the beam-centering camera

(PLFXT0269) to the computer using a
USB cable.

6. Open the Plugable 250X Digital USB

Microscope software.

7. Install the beam-centering camera

onto the tip assembly. See

Figure 7



Rotate the camera until it seats
fully against the tip retainer
assembly.



O-rings in the beam-centering

camera help keep it in place.
