Blackening Surface Treatment of Optical Cables

Home / Blackening Surface Treatment of Optical Cables

Black oxide, also known as blackening, is a precision conversion coating process used on ferrous materials that provides increased corrosion resistance. Stray light is energy outside of the clear aperture of an optical system that scatters off of the edges of an optical or mechanical component (Figure 1) and reaches the sensor in the form of noise (rather than signal). Edge blackening, using blackening paint, reduces stray light and enhances imaging by absorbing unwanted reflections.
