Abstract

A lens holder which is able to secure plural lenses in an adjustment-free fashion and to achieve relative positioning between the lenses to high precision. To this end, a first reference surface for the optical axis direction and a second reference surface for the optical axis direction of a second mounting portion are formed towards the object point side to serve as a reference surface for determining the separation along the optical axis between the first and second lenses . The first reference surface for the optical axis direction and the second reference surface for the optical axis direction also operate for controlling the tilt of the lenses
