Nano Black is a selective coating with differing characteristics for different wavelength regions:
- High absorptance / Low reflectance in the UV and VIS spectral regions
- Low emissivity in the IR
In satellites Nano Black is applied for solar thermal collectors and solar panels as well as for passive thermal management.
In addition to its unique optical performance Nano Black delivers many other attributes important in space applications:
- Essentially zero outgassing
- Vacuum and thermal-vacuum cycling compatible
- Operating temperatures from (-)269°C to (+)350°C
- No particulation
- Only a few microns thick
- Compatible with virtually all substrate materials
Participates at space programs: Canadian CAN X-2 and CAN X-7 nano—satellites; Chandrayaan ||- IR Hyperspectral spectrometer for the moon probe; and at the Robert Stobie Spectrograph (RSS/NIR) for the Southern African Large Telescope (SALT).
