SMA Spectrometer
This is the optical entrance that the fiber optic probe SMA connector return leg should be
connected to. Please rotate SMA connector clockwise to fasten.
SMA Laser output Spectrometer
This is the optical exit that the fiber optic probe SMA connector illumination leg should be
connected to. Please rotate SMA connector clockwise to fasten. The optical laser output is
protected by a microswitch, so only when the SMA connector is fully fastened the laser will
switch on.
DO NOT LOOK IN THE (REFLECTED) LASER BEAM, WEAR SAFETY GOGGLES AT ALL TIMES.
Interlock/doorlock
For a safe operation of the instrument it is required that interlocks are connected on every door to
the lab that the Raman is operated in. The delivered interlock will operate the laser without the
need for interlocks on the doors, but has to be replaced by interlocks on the doors.
