ABSTRACT:
A single fold optical magnifier including a plurality of optical elements having an aspheric field flattening light inlet with a light outlet directed at an angle to the inlet and a reflecting surface positioned to direct light from the inlet to the outlet. The optical elements define a light path from the inlet to the outlet with a total average optical length of approximately 15 to 35 millimeters. At least one aspheric surface and one diffractive optical element are positioned in the light path to provide aberration correction, and the optical elements are constructed to angularly magnify images by at least a power of ten.
