NanoLab developed a number of coating processes for the production of very high absorbance optical blacks for stray light suppression.
NanoLab offers two products to meet the needs of optical engineers:
Singularity Black and adVANTA Black.
Aligned carbon nanotubes (10 microns long) on Chromium lines (~10 micron wide) at site density about 5x10⁶/cm².
The whole structure was fabricated on a glass substrate.
Carbon nanotubes as long
as 20 microns on polished stainless steel sheet.
PECVD (plasma enhanced chemical vapor deposition) multiwall carbon nanotube suspensions are prepared by suspending the vertically aligned carbon nanotubes (harvested from Si substrates) into a variety of solvent
