Abstract: A telescope comprises a folding reflector comprising a plurality of sections configured to fold at a plurality of substantially parallel hinges, a support structure configured to support at least two of the plurality of sections of the folding reflector and further configured to fold at one of the plurality of substantially parallel hinges, a corrector assembly configured to deploy from a stowed position in which an optical axis of the corrector assembly is substantially parallel to the parallel hinges to a deployed position in which the optical axis is substantially perpendicular to the folding reflector when the folding reflector is deployed. The telescope further comprises a hexapod configured to stow and deploy the corrector assembly.

Abstract: A contact lens mould for producing a contact lens. The mould comprises a first mould half having a convex moulding surface of predetermined curvature, and a second mould half having a concave moulding surface of predetermined curvature. The first mould half is provided with an annular abutment surface which circumferentially surrounds and is contiguous with the convex moulding surface, and the second mould half is provided with a flexible annular lip which circumferentially surrounds the concave moulding surface.
