The 3rd generation efocus Fluorescence Microscope enables calcium imaging with cellular resolution over a larger brain area of freely-moving behaving animals. Its field of view has increased to 650 x 650 µm, and the electronic depth adjustment is 300 µm. A more sensitive sensor of the 3rd generation microscope requires less fluorescence excitation light, reducing photobleaching and phototoxicity. The microscope body attaches to the imaging cannula with a simple barrel rotation. No tools are required.

Notes: 

• The electrical and optical fiber tethers of an efocus Fluorescence Microscope Body Gen 3 are the same length.
• Every microscope body comes with a protective cap.
• The efocus Fluorescence Microscope Body Gen 3 is only compatible with the Twist-on efocus Imaging Cannulas.
