Medical Endoscopes Have Several Models, How To Choose The Typical Model For Type Test?

Generally, the following factors should be taken into account in the selection of typical endoscopes in one registration unit:

For endoscopes with different view angles, the model with the maximum view angle should be selected.

For endoscopes with different field of view angles, the model with the maximum and minimum field of view angles should be selected.

For endoscopes with different inner diameter, outer diameter and working length, the model with the smallest diameter and the largest slender ratio (length divide diameter) should be selected. If containing working channel, the diameter should be the outer diameter of insert minus the inner diameter of working channel.

For different optical performance (such as angular resolution, etc.), the model with the highest performance should be selected.
