摘要： Optical assemblies are provided including a barrel defining a cavity having a center axis, a sleeve inserted in the cavity, one or more optical elements mounted within the sleeve and a retaining ring inserted into the cavity and securing the sleeve. The sleeve engages the barrel inner wall through a thread engagement allowing a longitudinal displacement of the sleeve within the cavity. The retaining ring is also threadably engaged within the barrel, and the profile of the corresponding threads, as well as the spatial profile of a peripheral transversal surface of the sleeve engaging the retaining ring, are selected to provide a centering of the sleeve with respect to the center axis of the cavity throughout the longitudinal displacement of the sleeve.

摘要： An optical assembly is provided where an optical element is mounted in the cavity of a barrel. A flexible ring is in contact with one of the surfaces of the optical element. The flexible ring has ring threads engaging barrel threads within the cavity. The flexible ring has a biased state in which the ring threads press against the barrel threads, and is resiliently deformable to a compressed state allowing screwing of the flexible ring within the cavity. In one variant, multiple subassemblies each having an optical element and a flexible ring are provided in the cavity of a barrel. The optical elements of subassemblies subsequent to the first one are supported by the flexible ring of the previous subassembly. Advantageously, the pressing of the ring threads against the barrel threads prevents a lateral shift of the flexible ring within the cavity, eliminating the decentering observed with conventional retaining rings.

摘要： The auto-centering of an optical element within a barrel is provided. The optical element is mounted in a cavity of the barrel. A first surface of the optical element engages a seat provided in the cavity. A retaining ring is threaded on the barrel, through complementary barrel and ring threads. The retaining ring engages a peripheral region of a second surface of the optical element, thereby securing the optical element between the seat and the retaining ring. The profile of the barrel threads and the spatial profile of the peripheral region of the second surface are selected in view of an auto-centering condition whereby any decentering of the retaining ring and a corresponding tilt of the retaining ring have counterbalancing effects on the centering of the optical element. Optical assemblies and a mounting method are provided.
