Clean, Optical Black Finish for Space Telescope
2000
We are designing optical instrumentation for a scientific deep-space mission and are considering constructing one of our miniature telescope tubes of thin walled titanium.
We require an optical black finish with the following properties:
- extremely good adhesion, cleanable (scrubbable?)
- very low outgassing
- very low particulate generation
- good quality matte black or darker
Suggestions for black/titanium, titanium-black/copper, titanium-copper-black/nickel or any other candidate finishes will be appreciated. Geometries will be irregular cylindrical tubes 10-15 cm i.d. x 10-30 cm length.

When you mention optical spectrum, is it infrared, visible or UV?

I would consider black Ruthenium plating as it has good wear resistance. Ask your supplier for more details.
