Abstract
An optical assembly includes a lens assembly having a lens barrel for supporting a lens along an optical axis, an optical base having an opening aligned with the optical axis, and a plurality of ramps and a corresponding plurality of reference locators circumferentially arranged around the lens assembly and the opening in the optical base in order to slide against one another. A retaining element biases the lens assembly against the optical base with the ramps and the reference locators likewise biased therebetween against each other. Consequently, the ramps and reference locators provide an arrangement for focusing the lens assembly. The optical assembly also includes a factory focus tab attached to the lens assembly and accessible during the manufacturing operation for focusing the lens assembly by moving the ramps against the reference locators, and a focus adjuster assembly accessible during user focus for focusing the lens assembly by moving the ramps against the reference locators. The ramps thereby provide the adjustment of the lens position during both factory focus and user focus of the lens.
