Milestone 1A: Small-scale starshade mask in the Princeton Testbed demonstrates 1 × 10−10 instrument contrast at the inner working angle (IWA) in narrow band visible light and Fresnel number ≤ 15.
Milestone 1A: Small-scale starshade mask in the Princeton Testbed demonstrates 1 × 10−10 instrument contrast at the inner working angle (IWA) in narrow band visible light and Fresnel number ≤ 15.
Milestone 1B: Small-scale starshade mask in the Princeton Testbed demonstrates 1 × 10−10 instrument contrast at the inner working angle at multiple wavelengths spanning ≥ 10% bandpass and Fresnel number ≤ 15 at the longest wavelength.
