Abstract

An optical assembly adapted to be positioned within an endoscope tip and having three modular camera units, comprising: a front modular camera unit defined by a front central axis and a first and second side modular camera units defined by first and second side central axes that are substantially parallel to one another and substantially perpendicular to the front central axis. Each modular camera unit further comprises a holder for housing an associated optical element and an image sensor in data communication with a corresponding printed circuit board. The front, first side and second side modular camera units are respectively positioned in first, second and third compartments of an assembly holder.
