Negative Lens And Endoscope Objective

Patent No. EP3333599 (titled "Negative Lens And Endoscope Objective") was filed by Karl Storz on Nov 15, 2017. The application was issued on May 1, 2019.

Patent Summary

An endoscope objective comprises a deflection prism with an entrance face and a negative lens. The negative lens features a first face with a first optical surface and a second face with an opposing concave optical surface. The negative lens is mounted on the deflection prism's entrance face such that a rim encompassing the concave optical surface abuts said entrance face. The negative lens is characterized by a recess formed in the second face adjacent to the concave optical surface. This recess may be configured symmetrically or asymmetrically relative to the optical axis to enlarge the area of the planar entrance face available for total internal reflection, facilitating a cost-effective assembly that maintains image quality without requiring additional diaphragms.
