1. A method to manufacture an endoscope, the method including:
providing a camera assembly including a camera module, light emitting diodes (LEDs), a flexible circuit or circuit board having a first portion disposed adjacent a proximal surface of the camera module and LED powering portions connected to the LEDs, and an LED holder having first and second longitudinal portions extending from an interconnecting portion, the camera assembly having a distal end and a proximal end opposite the distal end, and the camera module including a distal lens having a distal surface;
providing a housing having a proximal end opposite a distal end, a distal end wall at the distal end, and a circumferential wall connected to the distal end wall and extending from the distal end wall to the proximal end of the housing, the circumferential wall and the distal end wall defining a spacing of the housing, the distal end wall comprising a camera window having a proximal surface;
connecting the first portion to the camera module, and attaching the LED powering portions onto distal ends of the first and second longitudinal portions of the LED holder;
after connecting the first portion to the camera module, inserting at least part of the camera assembly through the proximal end of the housing into the spacing to position the distal surface of the distal lens adjacent to and longitudinally aligned with the proximal surface of the camera window of the distal end wall of the housing;
filling at least a portion of the spacing with a liquid adhesive through the proximal end of the housing to at least partly embed the camera assembly in the liquid adhesive; and
allowing or causing the liquid adhesive to harden to attach the housing and the camera assembly to each other.
