4 To make the gain setting changes come into
effect you have to reset the controller. Alterna

tively, you can re-establish the contact to the
beamsplitter by the electronics as follows:
• Carefully lift off the interferometer compart-
ment lid.
Open lid:
Risk of exposure to laser light, which can
cause permanent eye damage.
➣ Do not stare into the beam.
• Open the beamsplitter looking door once.
This is necessary to make the gain setting
changes come into effect.
5 If the signal for one beamsplitter is too low (even with high gain setting) while
the others have good signal, this particular beamsplitter has to be replaced.
Details on changing a beamsplitter are described in chapter 5.8.
6 If the signal is too low for all beamsplitters while the optical alignment is cor-
rect, the laser power itself may have dropped or one of the optical compo-
nents in the laser beam may have been contaminated. The fiber patch cable
could be broken or misaligned. Contact Bruker service.
