Method and apparatus are presented for mass production manufacturing of
micro-mirrored balls for solar energy and related applications such as
optical switches, etc. For these applications it is imperative to provide
accurate specular reflection from the mirror. The mass production process
utilizes laminate sheets containing reflective material, assembly
rollers, and extrusion and die rollers. The micro-mirrored balls are in
the size range of 4 microns (4.times.10.sup.-6 m) to 1 mm (10.sup.-3 m),
and in one form are transparent in at least one hemisphere with a
reflecting mid-plane mirror. In other forms the micro-balls vary in
geometry from cylinders to oblate ellipsoids to disks. The term
"elements" is used to encompass all these shapes, which have one thing in
common--a flat specularly reflecting mirrored surface. These elements can
track the light source, and aim and focus the reflected light.
