Claims
- 1. An illumination device comprising
- (a) light source means including at least two active areas for producing uniform illumination in two dimensions, said active areas each being one of an xenon arc or a metal halide arc,
- (b) at least one reflector means for increasing said uniform illumination by reflecting light from said light source means, and
- (c) condenser lens means for passing light from said light source means and said reflector means, said at least one reflector means reflecting light not originally passing from said light source means to said condenser lens means.
- 2. An illumination device according to claim 1, wherein each of said active areas is a metal halide arc.
- 3. An illumination device according to claim 2, wherein each of said active areas has a length ranging from 0.3 to 1.5 inches.
- 4. An illumination device according to claim 3, wherein each of said active areas is at at most about 1.06 inches.
- 5. An illumination device according to claim 2, wherein said light source means is a 250 watt lamp.
- 6. An illumination device according to claim 1, wherein each of said active areas is an xenon arc.
- 7. An illumination device according to claim 6, wherein said xenon arc has an arc length of about 1 mm.
- 8. An illumination device according to claim 1, wherein each of said active areas maximizes light collection efficiency.
- 9. An illumination device according to claim 1, wherein said reflector means directs light between said active areas so that said condenser means images twice as many light images.
- 10. An illumination device according to claim 1, wherein said light source means directs light radially in substantially all directions including through said condenser lens means, and wherein said reflector means reflects light not originally passing through said condenser lens means.
