Mounting for high resolution projection lenses

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.
