The BP209CSA(/M) Adapter can connect a Thorlabs' BP209 Series Scanning Slit Beam Profiler to a 30 mm cage system. An SM1 (1.035"-40) threaded bore in the adapter allows for compatibility with our Ø1" lens tubes or a Ø1" optic up to 3.6 mm (0.14") thick, when secured with a SM1RR retaining ring (not included). Four blind holes with 5/64" (2.0 mm) hex locking setscrews accept Ø6.0 mm cage rods (not included).

To mount the BP209CSA(/M) to a scanning slit beam profiler, first rotate the Y scan axis of the beam profiler to +60° or -60°, then turn the unit upside down, allowing access to the bottom mounting plate. Use the 2.0 mm (5/64") hex key included with the BP209CSA(/M) adapter to remove the four 5 mm long, M3 x 0.5 hex socket head screws*. Fully remove the bottom plate on the beam profiler, and mount the BP209CSA(/M) adapter in its place using the screws removed from the beam profiler.

*For BP209 Series Dual Scanning Slit Beam Profilers made prior to July 2022, the bottom plate is secured via four 5 mm long, M3 x 0.5 Phillips head screws. A #1 Phillips screwdriver (not included) is required to remove these screws.
