Rod lens systems utilize specialized glass rods with precision-finished optical ends. These systems provide images with significantly higher brightness, contrast, and superior color reproduction compared to conventional lens designs.
Rigid endoscopes typically feature a sequence of high-resolution optical glass rod lenses. These instruments support forward viewing (0 degrees) or angled viewing (10-120 degrees), enabling visualization beyond the telescope's axis and expanding the Field of View (FOV) through instrument rotation. The optical quality achieved by these rod lenses continues to outperform fiber-optic or digital imaging in flexible scope applications.
