Abstract
An optical device for providing a visual warning indication is disclosed. The optical device includes a high intensity localized light source such as a laser diode and a diffuser for modifying a beam intensity distribution of the emitted light from the high intensity localized light source to generate diffused light. The device further includes a collimator for collimating the diffused light from the diffuser to provide collimated light for emission from an output aperture to provide the visual warning indication. The beam intensity distribution of the emitted light is modified by the diffuser to generate a substantially uniform intensity distribution of the collimated light over the entire output aperture.
