1. An image sensing device comprising:
a lens tube having a back wall and a tubular sidewall extending away from the back wall to define a front aperture opposite the back wall;
a lens housing disposed within the lens tube and coupled to an interior surface of the tubular sidewall;
a bulk lens system mechanically coupled to the lens housing and configured to focus light received through the front aperture to an image plane, the bulk lens system comprising a plurality of lenses; and
an array of photosensors coupled to the back wall of the lens tube at the image plane of the bulk lens system, the array of photosensors configured to receive light from the bulk lens system;
wherein, as the image sensing device is exposed to increasing temperatures, the lens housing elongates shifting the image plane in a first direction towards the back wall of the lens tube while the lens tube expands shifting the image plane in a second direction, opposite the first direction, to compensate for elongation of the lens housing.
