Ordering Code:

  • The Twist-on Reduced Footprint Imaging Cannula has been designed with an outer diameter of the base as small as 3.5 mm to image exiguous area of the brain (e.g. olfactory bulb). In the Twist-on Reduced Footprint Imaging Cannula, the GRIN lens protrusion length is user defined with steps of 250 microns. There is no protrusion adjustment ring. Twist-on Reduced Footprint Imaging Cannula are compatible with the efocus Fluorescence Microscope Body (eTFMB, eTOSFM)

    Notes: The protrusion length of the GRIN lens is determined from the base of the imaging cannula to its tip.
