US Patent 8662683 Retro-reflective marker

A reflector body (10), particularly a spherical retro-reflective marker, includes a plurality of reflector body segments (11), and the individual reflector body segments (11) formed by such a reflector body (10), and there are methods for producing the reflector body segments (11) and the reflector body (10). The reflector bodies (10) include a coating having a reflection film (12), by which the reflector body segments (11) of the reflector body (10) are uniformly spanned, performed by suitably selecting the geometric shape of the reflector body segment (11) to be spanned, by injecting molding behind the reflection film (12) in an injection molding process and/or by producing the reflector body segments (11) in a forming process.
