20110163465 | METHOD OF CONSTRUCTING A THIN FILM MIRROR - Method for producing a large size mirror from a thin film, involving (a) the attachment of a thin film to a suction chamber, the edge of which has the required geometry of the mirror, and (b) the production of a controllable partial vacuum in the suction chamber so that the thin film takes on the required geometry of the mirror. The method is characterized in that the region of the mirror having the required geometry is enlarged by preshaping the thin film, prior to the attachment thereof to the suction chamber, by controlled tensioning in a closed pressurization chamber comprising two circular discs with a common axis and a thin film which is attached to the edges of the discs and the lateral sides of which are conjoined so as to form a conical surface, and by additionally tensioning the thin film by means of a mechanism for moving the discs apart along the common axis thereof. In order to facilitate and accelerate the process of forming a mirror from a thin film, the pressurization chamber together with the thin film attached thereto is placed in a thermal box in which the film is uniformly heated to an optimum temperature for deforming the film under increased pressure in the pressurization chamber. | 07-07-2011 |

20130161845 | METHOD OF FORMING AN OPTICAL SURFACE ON A SOLAR COLLECTOR SHELL - A method of forming an optical surface on a solar collector that is made from a composite material adds epoxy to the collector. The epoxy is applied to a mandrel that has an outer surface shaped to conform to a concave side of the collector. The concave side of the collector is laid over the mandrel and into contact with the epoxy. The collector is set on the mandrel by first aligning one of the elongate edges of the collector with an elongate edge of the mandrel. Pivoting the collector about the interface defined between the edges of the collector and mandrel produces a wave front in the epoxy, so that when the collector is laid down onto the mandrel, a substantially uniform layer of epoxy is disposed between the collector and mandrel. Heating the resin bonds it to the collector and forms a substantially smooth optical quality surface. | 06-27-2013 |
20160024648 | Process for making triple graded CVC-CVD-CVC silicon carbide products - A chemical vapor composite process for making high quality silicon carbide suitable for optical and structural components with low intrinsic stress and high thermal stability. In the CVC process solid micron-scale silicon carbide particles are incorporated into a high purity chemical vapor stream and injected into a high temperature furnace. Three layers of silicon carbide are vapor deposited on the graphite mandrel. The first layer is a sacrificial layer, deposited utilizing the chemical vapor composite process. The second layer is the optical cladding CVD layer, which is deposited by continuous deposition of the high purity chemical precursor without the silicon carbide particles. This layer is ground and polished to a high optical finish. The third layer is the bulk of the mirror structure and deposited via the CVC SiC process as described above. The thickness of this structural layer is determined by the product's geometrical and structural requirements. | 01-28-2016 |
