CODE GENERATOR


The new e-focus Fluorescence Microscope is the next step in miniature deep brain imaging. Using a state-of-the-art electronically adjustable lens, its working distance can be adjusted via software even while the animal is freely behaving in an open field. Users can remotely adjust the depth of the field of view, which increases detection volume, measurement efficiency and implantation success rate, while allowing more flexibility in imaging location.

The depth is adjusted by up to ± 45 µm relative to the designed working distance of the cannula (e.g. with an imaging cannula aligned at a working distance of 100 µm, the depth of the structures imaged can be adjusted from 55 to 145 µm below the tip of the GRIN lens).

For more flexibility, the microscope body is fully connectorized, allowing easy cable selection and replacement. Its small size and minimal weight make it ideal for use with mice, rats and other small animal subjects.

Notes:
• 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.
