LIGHT GUIDE HAVING CONDENSER LENS

摘要

PURPOSE:To eliminate a special tool to secure a close adhesion with a high accuracy and thus avoid an error for a long period of time, by sticking a rod lens as a condenser lens at the light emission end of a light guide consisting of optical fibers. CONSTITUTION:A rod lens 4 is stuck as a condenser lens to the light emission end surface of a light guide 1 consisting of plural optical fibers. As a result, the accuracy of attachment is increased with an easy attachment to secure a stable holding without causing any shift of position of the lens 4 for a long period of time. Thus such light guide can be suitably applied to a miniature gastrocamera or the like.
