ABSTRACT:
Mounts for plastic lens elements of differing diameters or materials include a separate V-block for mounting each lens element, wherein the V-blocks for lens elements of a smaller diameter converge at angles less than V-blocks for lens elements of a larger diameter, the angles of convergence being selected so that the centers of the lens elements remain aligned with an optical axis perpendicular to both of the lens elements upon thermal expansion of the lens elements.
