Abstract
An elongated optic (12) is supported within a cylindrical housing (18) by a pair of support rods (14) passing through the cylindrical housing (18). A resilient retention spring (16) diametrically opposed to each support rod (14) presses the elongated optic (12) against the support rod (14) to prevent movement by the elongated optic (12) while allowing the elongated optic (12) to expand and contract. Contact between the support rods (14) and the resilient retention spring (16) is minimized to prevent inhibiting the internal reflectivity of the elongated optic.
