1. An endoscope comprising:
- a proximal end comprising a control portion;
a distal end comprising a distal tip, wherein said distal tip comprises;
a lens holder,a lens received by the lens holder,a sensor device comprising;
a vertical portion,a horizontal portion, anda first component of a movable coupling, wherein the first component is coupled to the horizontal portion, anda second component of the movable coupling, wherein the second component has a fixed position relative to the lens, wherein the first and the second components are movably coupled to each other and configured to move proximally and distally relative to each other, upon actuation of the control portion, to adjust a distance between the vertical portion and the lens.

Abstract
The present specification describes a novel system for dynamically modifying the magnification power of optical devices used in high performance and critical applications such as medical procedures. The present specification describes an optical imaging system having a magnification control system connected to a sensor device for enabling movement of sensor device with respect to a lens assembly of the imaging system, wherein distance between the sensor device and the lens assembly is altered to enable different levels of magnification capability.
