 Most often a fiber collimator (FC/PC or FC/APC) is used to couple the excitation beam into the scanner, or free-space coupling is possible.  The output is C-mount threads that easily attach to an ASI tube lens (i.e. the scan lens is an integral part of the scanner itself).  In order to scan the beam exactly parallel to itself 4f spacing needs to be maintained between the MEMS mirror and the sample, meaning that the spacing between the scanner tube lens and objective back focal plane needs to be correct. Most often a fiber collimator (FC/PC or FC/APC) is used to couple the excitation beam into the scanner, or free-space coupling is possible.  The output is C-mount threads that easily attach to an ASI tube lens (i.e. the scan lens is an integral part of the scanner itself).  In order to scan the beam exactly parallel to itself 4f spacing needs to be maintained between the MEMS mirror and the sample, meaning that the spacing between the scanner tube lens and objective back focal plane needs to be correct.
