Mounting for high resolution projection lenses

Claim 1

A lens mount comprising: a lens having a first surface of spherical configuration and a second surface; a lens cell having a top surface, a bottom surface, an outer diameter and an inner diameter; said outer diameter being concentric about an axis of rotation of said lens cell; said top surface and said bottom surface being substantially perpendicular to said axis of rotation; a lens seat projecting inwardly from said inner diameter; said lens seat having a radius of curvature match-mated to the curvature of said first surface of said lens; the rotational symmetry axis of said lens seat being coincident with the axis of rotation of said lens cell; the first surface of said lens being substantially in contact with said lens seat; the optical axis of said second surface being aligned substantially coincident with the axis of rotation of said lens cell; a plurality of flexures holding said lens to said lens cell; each of said flexures being removably attached to said lens cell; each of said flexures comprising: a flexure assembly attached to said lens cell; a flexure arm attached at both ends to said flexure assembly and at its center to said lens; and said flexure arm being substantially parallel to and spaced from said flexure assembly.
