The Twist-on efocus Fluorescence Microscope enables users to visualize larger brain areas in freely behaving animals studies. The large field of view of up to 650 x 650 microns and the electronic depth adjustment of 300 microns allows a larger volume to perform calcium imaging at cellular resolution. This microscope offers an optimized way to attach the microscope body to the imaging cannula with precision, with a simple barrel. The attachment/detachment is now easier and does not require any tools.
Motor assisted rotary joint (AHRJ) and dummy microscope bodies are available on option.
