Two 3D models of prism nerve holder for small and large diameter peripheral nerves.

The complete nerve holders require installation of mirror prisms (2x3mm prisms for small diameter version, 4x5mm prisms for large diameter version), and small magnets (1.5mm diameter) for being able to attach to an optical head of the imaging system at pre-defined distance.

Both nerve holders introduce a slight tilt for the prisms to minimize the specular reflection.
