DFM Engineering has provided ten heliostats.
They have driven the light from the equatorially mounted flat mirror upward along an extension of the polar
axle to a number 2 mirror that has folded the light vertically downward.
We have developed a special polar alignment technique for heliostats.
Equatorially mounted flat mirror
4 degrees per second axes motion
Mirror front surface located at the intersection of the axes
On axis 1 arc second resolution encoders
Computer control system
