Shutter
The built-in laser shutter is electromechanical and is software controlled via the RS-232
or USB interface. If the safety interlock is opened or a fault occurs, the shutter closes
immediately.
Cover Safety Interlocks
The laser head does not contain user-serviceable parts and is not to be opened by the
user. The covers for both the laser head and laser power supply are secured with
fasteners that require a tool to open. Only trained service personnel may remove these
covers. Therefore, the laser head does not require cover interlocks. As a warning, a
non-interlocked label is attached to the laser head as shown in
Figure 2-8. Only someone
trained by Spectra-Physics should be allowed to service the system.
Interlock Keyswitch
The keyswitch on the rear panel of the laser head (Figure 2-5) provides interlock safety
to prevent unauthorized personnel from using the InSight X3 laser system when the key
is turned to the off (horizontal) position and the key is removed. Turning the key to the
enable (vertical) position allows the laser diode to be energized if (a) the power supply
AC power switch is also on and (b) an ON command is given.

interlock
Operating the laser with the cover off may expose
people to high voltages and high levels of radiation. It
also increases the rate of optical surface
contamination. There are no user-serviceable parts
inside the InSight
X3 laser head. Operating the laser or
the power supply with the aluminum cover off is
prohibited and doing so voids your warranty.
