Ribbed Telescope Mirrors With Thermal Gradient Control
US Patent:
8439509, May 14, 2013
Filed:
Aug 17, 2007
Appl. No.:
11/840787
Inventors:
Richard A. Schwartz - Hawthorne CA, US
International Classification:
G02B 7/182
US Classification:
359848, 359871
Abstract:
Ribbed mirrors allowing heat to be conducted past the glass during optical polish and application of coatings and methods of fabricating same. The method comprises placing a bridge of thermally conductive material in thermal contact with the mirror plate and the supporting rib at the interior angle. The preferred thermally conductive material is room temperature vulcanizing silicone. However, the room temperature vulcanizing silicone can be mixed with a powdered heat conductor such as diamond dust, aluminum oxide and silicon carbide. Alternatively, the thermally conductive fillet can be made from a segment of thermally conductive rigid material, such as copper, diamond, beryllium, silver and aluminum having an exterior angle matching the interior angle and a thermally conductive plastic such as room temperature vulcanizing silicone or thermally conductive grease, silicone or epoxy applied to surfaces of the exterior angle.

Mount For Telescope Mirrors
US Patent:
5877905, Mar 2, 1999
Filed:
Apr 14, 1997
Appl. No.:
8/834638
Inventors:
Richard A. Schwartz - Hawthorne CA
International Classification:
G02B 508, G02B 7182, A47F 114
US Classification:
359846
Abstract:
An improved support for a telescope mirror using a system of three bars which are joined at their ends to the back of the mirror with compliant adhesive pads. Preferably, one end is joined to the center of the mirror while the others are joined on the circumference of a circle centered on the center of the mirror. In this preferred embodiment, there is an approximately right triangular relationship between the centers of the bars. The backs of the bars are coupled at their centers to mirror adjusting mechanisms by further compliant pads. The numbers of support points can be increased by coupling further bars or triangles between the circumferential support points of the original three bars and the back of the mirror. Again coupling is provided by compliant adhesive pads. The thickness and size of all pads are controlled to provide stiff support in compression and shear along with resilient support in bending.
