Abstract
A thermally compensating lens mount (40) comprises an axially symmetric housing (42) that is formed from an inner layer of a first material (44) having a low coefficient of thermal expansion (CTE) to an outer layer of a second material (46) having a high CTE. The longitudinal cross-section of the housing (42) has a barrel shaped geometry along the symmetry axis (47) so that differential thermal expansion of the first and second materials (44, 46) decreases the length of the housing (42) along its axis of symmetry (47) by an amount determined by the CTEs of the inner and outer layers (44, 46), their thicknesses, and the geometry of the barrel shape.
