Endoscopic Rod Lens

Endoscopic rod lenses and objective lenses are critical precision optical components within rigid endoscopes, forming the core of the imaging system. The objective lens, located at the distal (patient) end, captures the initial image inside the body. The rod lens series acts as a relay system, transmitting the image formed by the objective with extremely high fidelity to the eyepiece or camera sensor. Their performance directly dictates the endoscope's image quality, resolution, and reliability.
