mesoSPIM_excitation_path_L1_collimation
Use another CPVM plate to set up the laser collimator. Add two 4-inch cage rods to the bottom, and screw in the 75 mm collimation lens on the bottom side.
Add the laser shutter with its cageplate and a standard SM1 cage plate with the SM1FCA fiber adapter. Fixate the SM1FCA and the shutter inside their respective cageplates so that their distance is minimal.
A SM1L10 tube and a SM1V10 adjustable lens tube can be used to move the entire stack of the two cage plates axially for collimation under control of a shearing interferometer.
