Compare black-coated foils and IR Flock Sheet for optical applications. Learn how they differ in reflectance, durability, cost, and infrared performance to choose the right material for stray-light suppression in aerospace and testing environments.

Simulating space on Earth isn’t just about darkness—it’s about controlling the right wavelengths. Learn how VL Flock Sheet creates visual darkness for human eyes, while IR Flock Sheet minimizes infrared reflections for sensors, helping you choose the right material for optical testing and simulation environments.

The Black Market conducted a research project comparing the darkness of four commonly available black papers: Plike Black, NT Rasha Shikkoku, OK AC Card Makuro, and Daiso Black Colored Drawing Paper. Visible light reflectance measurements showed NT Rasha Shikkoku had the lowest average reflectance at 3.35%, followed by Plike Black and OK AC Card Makuro at around 4%, while the Daiso paper measured 6.02%, roughly twice that of NT Rasha. NT Rasha Shikkoku was determined to be the darkest of the four papers tested, though the comparison was limited to domestic options. The article also showcases a comparison between NT Rasha Shikkoku and the brand's own Fineshut SP material, which is used for stray light prevention in optical equipment.

Discover the world’s blackest permanent marker in a head-to-head showdown of top brands including Sharpie, Tamiya, Pilot, Zebra, and more. This in-depth comparison focuses exclusively on blackness, using scientific measurements of light absorption to determine which marker delivers the deepest, darkest black.
