title: [Rod-like optics of endoscopes].
abstract: The optical characteristics of endoscopes can be made more effective and the quality of the image improved through incorporation in their optical systems of rod-like components. The use of rod-like components in the rigid choledochoscope helped increase three-fold the optimal efficiency by comparison with that in the formerly manufactured device provided with an optics that was made up of small thickness lenses.
