Abstract:
1. Apparatus for synthesis of arrays of chain molecules comprising: (a) a substrate with an active surface on which the arrays may be formed; (b) a light emitting object array configured to emit a pattern of light and dark areas; and (c) projection optics configured to receive the light emitted from the light emitting object array and to image the pattern of light and dark areas onto the active surface of the substrate, the projection optics comprising a first, concave mirror configured to receive the light from the object array and to reflect that light at an angle off the axis of the light received from the object array, a second, convex mirror configured to receive the light reflected from the first mirror and to reflect the light off the axis of the light received from the first mirror, a third, concave mirror configured to receive the light reflected from the second mirror and to reflect the light off the axis of the light received from the second mirror, and a fourth, convex mirror configured to receive the light from the third mirror and to reflect the light off the axis of the light received from the third mirror and to image the light onto the active surface, the first, second, third and fourth mirrors arranged to form a magnified image of the pattern of light and dark areas at the active surface.
