0 Degree Rigid Oto Endoscope is a precision optical instrument designed for detailed visualization of the external auditory canal and tympanic membrane during ENT examinations and procedures. Its straight, 0-degree viewing direction provides a direct line of sight, while the rigid construction and optical system support clear visualization of delicate ear structures. Rigid oto-endoscopes are commonly available in compact diameters and are designed for use with compatible light sources and imaging systems.
