To compensate for a focal plane shifting away from an image plane due to a temperature change, an integrated image sensor and lens assembly includes an optical component and an optics compensator including passively actuating elements. The passively actuating elements couple the optical component to the inner surface of the lens mount. The passively actuating elements and the optics component are configured such that the focal plane is maintained to coincide with or substantially coincide with the image plane. The passively actuating elements and the optics component adjust the distance an incident ray travels in the optics compensator when the temperature changes to thereby maintaining the focal plane to coincide with or substantially coincide with the image plane.
