Abstract

This paper presents a method for designing an add-on lens assembly to optimize the performance of Chip-on-the-Tip (COT) endoscope. In particular, an add-on lens assembly is designed here attributes to a commercially available COT camera, NanEye, in such a way that overall optical performances such as field-of-view (FOV) and depth-of-field (DOF) are optimized for the particular microsurgery at hand: Epiduroscopic surgery. The add-on lens assembly is designed with four lenses compactly assembled into 1.3 mm length and 1.52 mm diameter. It provides a FOV of 110° and DOF of 1.5 mm to 8 mm under the refractive index of water, greatly increasing the native 62° FOV of NanEye in the air (90° in the air) to 110° while decreasing the minimum DOF from 3 mm to 1.5 mm.
