Ultrablack Coatings Achieve Broadband Absorption for Precision Optics
SHANGHAI, March 21, 2024 — A broadband, ultrablack film from the University of Shanghai for Science and Technology and the Chinese Academy of Sciences could enhance the performance of telescopes among other applications in space exploration and precision optics. In tests, the film achieved an average absorption as high as 99.4%, within a wavelength range of 400 to 1000 nm. Optical devices that require ultrablack coating for stray light suppression often exhibit significant curvature and intricate shapes,
Adaptive Optics Elevates Ground-Based Telescopes’ Image Quality
