New Ultrablack Coating to Revolutionize Space Telescopes

Researchers develop a coating that absorbs over 99% of light, promising significant advancements for optical equipment in extreme environments.

Researchers have developed an ultrablack coating that absorbs 99.3% of light, significantly enhancing the performance of telescopes and optical equipment.
The coating, made from alternating layers of aluminum-doped titanium carbide and silicon nitride, can be applied to complex surfaces and withstand harsh conditions.
Atomic layer deposition (ALD) technique allows for uniform coverage on intricate shapes, making it ideal for aerospace applications.
The ultrablack coating's durability and light absorption capabilities could improve the efficiency of space observatories like the Hubble and James Webb Space Telescopes.
Future improvements aim to expand the coating's light absorption range to include ultraviolet and infrared regions.
