Reflex reflector

The Reflex reflector is a lens meant to reflect light.

Note: This beam type is only compatible with the Honeycomb lens.

Retroreflectors are composed of small corner reflectors (truncated cubes) that redirect light back to its source.

Reflex reflector lenses are designed to reflect light in the same direction as incident light.

With this beam type, no further definition is required. But you can:

  • adjust the offset of the group from the intermediary surface (thanks to the Shift parameter).
  • adjust the angular spacing between the input and reflected ray (thanks to the Angle parameter).

    The Angle parameter allows you to control the cubes' corners flattening. This adjustment impacts the spacing/spread of the reflected points. The 6 reflected points correspond to the 6 retro-reflections on the corners of the cube.

Note: According to ECE R3 regulation on retro-reflecting devices, available on the Ansys Library, the measurements are made around the direction of the source within 20 arc minutes (0.33˚) and 1˚30 arc minutes (1.5˚).
