The Twist-on efocus Fluorescence Microscope enables users to visualize larger brain areas in freely behaving animals studies. The large field of view up to 650 x 650 microns and the electronic depth adjustment of 260 microns allows a larger volume to perform calcium imaging at cellular resolution. This microscope offers an optimized way to fix the body to the imaging cannula, with a
simple barrel. The attachment/detachment is now easier and does not require tweezers.
• The Electrical Cable for efocus Fluorescence Microscope Bodies is required for the use of this device.
• The optical fiber length is adjusted to fit the desired electrical cable length.
• Every microscope body comes with a protective cap.
• The Twist-on efocus Fluorescence Microscope Body is only compatible with the Twist-on efocus Imaging Cannulas.

For deep brain regions (0 mm to 8 mm deep) use the Twist-on efocus Imaging Cannula Model L that brings the image from inside the brain to the skull surface with an image guiding gradient-index rod lens.
The Twist-on efocus Dummy Microscope is a look-alike, inexpensive replica of the Twist-on efocus Fluorescence Microscope Body that fits any Twist-on efocus Imaging Cannula.
This system contains all the items necessary to do deep-brain calcium imaging of freely-moving animals with the possibility of electronic adjustment of the distance between the implant tip and the focal plane.
