Abstract:
We demonstrate a new design high-contrast optics suitable for use on a
stray-light reduction. Two-dimensional distribution of diffracted light was numerically analyzed and confirmed by a laboratory
measurement to determine its characteristics. Laboratory measurements confirm stray-light performance with ∼ 10 − 8 rejection viewing as close as 1.0° to
a bright-light source. The present improvement replaces the conventional normal-edge vane by an edge with microscopic
Gaussian-shaped structures. This permits simplified fabrication, provides even more weight reduction, and delivers improved performance
for a given size.
