A lens mount assembly for securing a lens in a predetermined position within an optical device is disclosed. The lens mount assembly is configured so as to retain the lens in a press fit arrangement, thereby eliminating the need for adhesives or other mechanical means in order to secure the lens. In one embodiment the lens mount assembly includes a glass lens having an outer surface with a predetermined amount of surface roughness. A retention tube defines a cylindrical volume and is composed of a compliant material that resiliently deforms when the lens is pressed into the cylindrical volume. The compliant material recompresses a small amount around the lens to secure it within the retention tube. A base is attached to or integrally formed with the retention tube and includes a corrugated surface for securing the lens mount assembly within the optical device.
