A retroreflector is a highly unique and practical optical component, specifically a glass prism defined by three mutually perpendicular reflective surfaces, resembling a corner cut from a cube. Its defining property is the ability to reflect incoming light precisely back along its original path, regardless of the angle of incidence.
Extremely high retroreflective accuracy with virtually no angular deviation.
Excellent durability, typically made of glass.
Relatively larger size and weight.
