Abstract

An apparatus for maintaining registration of a lens assembly in a consistent position over a sensor by positioning the sensor adjacent a sensor mount instead of a housing encompassing the lens assembly and sensor. The apparatus comprises a lens assembly having at least one predetermined focal center, and a lens barrel for holding the lens assembly. A holder adjustably supports the lens barrel, the holder having a base and a cylinder, with the lens barrel adjustably mounted in the cylinder. The base of the holder is attached to a support, such as a circuit board, whereby the focal center of the lens assembly is held in a predetermined aligned position relative to the sensor. In an embodiment, wall surfaces defining an opening in the base of the holder firmly engage the sidewalls of a ceramic sensor mount.
