Abstract:
1. A molding bench for curving a plurality of mirrors having different curvatures, the molding bench comprising: a sheet supported on a frame the sheet having a lower part to which is fixed a series of air pipes connected to a vacuum pump; wherein the sheet comprises a square lattice with intersections, the intersections having perforations, the perforations being functionally connected to the series of air pipes to create a series of suction points at the perforations; and a series of tensors functionally connected to the sheet and the frame, wherein the series of tensors are configured to adjust a series of distances between the sheet and the frame; wherein the suction points are dimensionally calibratable by adjustment of the series of distances between the sheet and the frame using the series of tensors to have the dimensions to be achieved at each point of a first mirror having a first curvature, and are further dimensionally calibratable to have the dimensions to be achieved at each point of a second mirror having a second curvature different from the first curvature.
