The inspected target field is imaged on the sensor by an optical lens with a dynamic mechanical module. A microgear and motor are used to drive the dynamic lens components, and a compensation element is used in the system to correct the aberrations due to the protective cylindrical endoscope cover. A long depth of field navigator lens is attached to image the front side. The design details are presented and results are shown. © 2014 Optical Society of America.Endoscopy; Depth of field; Dynamic mechanical; Lens system designs; Micro gear; Novel structures; Optical lens; Target fields; Videoscope; Optical instrument lensesjournal article10.1364/AO.53.00H1462-s2.0-84942364391
