Ensure that DC power to the laser is turned off and locked out before
inspecting optical components in the beam path.

radiation is emitted through the aperture. Corneal damage or blind-
ness may result from exposure to laser radiation.
Troubleshooting
Symptom:
■
It is necessary to isolate the i401 laser from the IT network, but still important to access the i401
web page from a networked control computer.
Possible Causes:
■
Use a USB to Ethernet adapter to isolate the Firestar i401 laser from the network.
In situations where it is necessary to isolate the Firestar i401 laser from your internal IT network, but
still access the i401 web page from a networked control computer, you can connect the i401 laser to the
networked computer using a USB to Ethernet adapter. Devices like the TRENDnet TU2-ET100
USB
to 10/100 Mbps Adapter
allow your networked computer to access the Firestar i401 web page over the
computer’s USB port, which isolates the laser from your computer network. In this case, use a crossover
Ethernet cable between the i401 laser and the USB to Ethernet adapter.
Beam delivery optics
Symptom:
■
The laser loses power over time; laser output power must be increased to maintain performance.
Possible Causes:
■
Beam delivery optics are coated by vapor residue or debris.
Shut down the laser and carefully inspect each optic in the beam delivery path. If the optic requires clean-
ing, refer back to
Maintenance
for cleaning instructions. Use only recommended cleaning materials (see
Table 4-1) to prevent scratching delicate optical surfaces. If the focusing optic is pitted, it must be replaced
immediately. Because of the extremely high power density of Firestar lasers, pits or debris on the lens
surface may absorb enough energy from the focused beam to crack the lens. If this happens, other optics in
the beam path may be contaminated or damaged as well.
