The External Relay Lens is designed to be placed in Snap-in Imaging Cannulas so that external microscopes (e.g. two-photon microscope) can acquire images through the GRIN lens of the Imaging Cannula without being obstructed by the cannula mechanical part. This allows the external microscope as well as the Doric Miniature Fluorescence Microscope to image the same ROIs and combine the advantages of both microscopes.
