Patent Images
1. An imaging module for endoscopes comprising:
- a fundamental module including a convex lens and an image sensor that are fixedly positioned relative to one another; and
an optical module selected among a plurality of optical modules each of which is constructed to be mountable to the fundamental module, the imaging module being formed by mounting the selected optical module to the fundamental module,wherein an observation condition is switched in accordance with the selected optical module mounted to the fundamental module, andwherein an image position and an angle of oblique incidence of light of an observation image on the image sensor are practically unchanged irrespective of which one of the plurality of optical modules is mounted on the fundamental module.

Abstract
An imaging module for endoscopes includes a convex lens and an image sensor in which mutual positions are fixed and a plurality of optical modules that are selectively mountable with respect to the fundamental module so that the observation condition is switched in accordance with an optical module selectively mounted. The imaging module for endoscopes is constructed so that when each of the optical modules is mounted to the fundamental module, an image position and an angle of oblique incidence of light of an observation image on the image sensor are practically unchanged.
