Nano BlackTM Coating

  • Low reflectance in UV and VIS combined with high reflectance in IR
  • Typical applications: space, quantum atomic clocks, thermal passive managements (space and other), wafer level optics
  • Selective black coating
  • Low infrared emissivity
  • Exthremely thin - typically below 1.5µm

Typical Properties

nano black coating reflectance chart

Nano Black is applied for thermal passive management (space and other), wafer-level optics, and highly precise instrumentation like atomic clocks.

In addition to its unique optical performance, Nano Black delivers many other attributes important in space applications:

  • Low outgassing
  • Operating temperatures from (-)70°C to (+)200°C
  • No particulation
  • The coating thickness ≤ 1.5 µm
Metals, glass, ceramics, polymers
Adhesion test (ref ECSS-Q-ST-13C)
Coated pieces withstand scotch tape test (3M853 Crystal Clear tape, strength of 13N per 25mm), without any evidence of coating removal.

"Coated pieces withstand cleaning with ethanol, IPA or acetone with no change in optical and technical characteristics. Magic Black™, Metal Velvet™ and Litho Black™ should be cleaned very gently."
