Laser beam transmitter lighthouse

摘要

A laser transmitter projects a beam of laser light and rotates the beam about an axis which is generally normal to the beam. The transmitter includes a laser beam source, and a lighthouse. The lighthouse encloses, at least in part, the laser beam source while permitting the beam of laser light to be projected there through. The lighthouse includes a plurality of transparent panels, and a panel support of elastomeric material. The panel support engages the plurality of transparent panels and supports them in a peripheral configuration such that they surround the laser beam source.
