Endoscope objective lenses are critical optical components in endoscopic systems, delivering high-quality imaging for internal cavity inspection. Designed to meet strict medical standards, our objective lenses feature high resolution, wide field of view, and excellent light transmittance, while maintaining a compact size suitable for narrow endoscope structures.
The objective lens system effectively expands the field of view and adopts an image-space telecentric design, ensuring stable and precise coupling with the relay lens system.
