Rigid Fantastic Optical Cylindrical Lens Rod Lenses For Medical Endoscopes
Rod Lenses for Rigid Endoscopes
Rod lens systems use special glass rods with optically finished ends, providing images with higher brightness, contrast and colour
reproduction than conventional lenses.
Commonly, rigid endoscopes have a series of high-resolution optical glass rod lenses. The endoscopes can be forward viewing (0
degrees) or angled (10–120 degrees) to allow visualization out of the axis of the telescope and increase the FOV by rotating the
instrument. The optical quality of lens-generated images of rigid endoscopes still surpasses that of the fiber-optic or digital
images produced by flexible scopes.
