Twist-on efocus Fluorescence Microscope Body (OBSOLETE)

  • Unit price per 

Ordering Code:
  • The Twist-on efocus Fluorescence Microscope lets users select appropriate focal plane within larger brain area of freely behaving animal remotely with an electrical signal. Its field of view of up to 650 x 650 microns and the electronic depth adjustment of 300 microns allow cellular resolution calcium imaging over a larger volume. The attachment/detachment of the microscope body to the imaging cannula is done with a simple barrel rotation and does not require any tools.

    Notes:Ā 
    ā€¢ The electrical and optical fiber tethers of an efocus Fluorescence Microscope Body are of the same length.
    ā€¢ Every microscope body comes with a protective cap.
    ā€¢ The Twist-on efocus Fluorescence Microscope Body is only compatible with the Twist-on efocus Imaging Cannulas.
