Typical Properties

 

Magic black reflectance chart

Magic BlackTM is the coating of choice where the absolute lowest reflectance / highest emissivity is required in the FUV — UV, VIS up to SWIR regions – typically for stray-light suppression.

In addition to its superior optical performance Magic BlackTM delivers many other attributes important in space applications:

  • Essentially zero outgassing
  • Vacuum and thermal-vacuum cycling compatible
  • Operating temperatures from (-)269°C to (+)380°C
  • No particulation
  • Only a few microns thick
  • Compatible with virtually all substrate materials

Magic BlackTM was thoroughly tested and qualified for thermal cycling, thermal vacuum cycling, cryogenic temperature performance, outgassing, space atomic oxygen, reflectance after environmental exposure, adherence. Detailed BRDF data is available.
