Self leveling transmitter for laser alignment systems

摘要: A transmitter for an alignment system in which a field of electromagnetic radiation is propagated non-planar reference cone disclosed. The includes source providing collimated beam directed parallel to axis. cantilever strand supports bob within the beam. has conical reflecting surface reflect conically. Optimally, and are chosen provide deflection between plumb substantially one-half any angular error axis plumb. In especially preferred form, housing surrounds inner outer surfaces minimize temperature effects on orientation plane. Also, detectors provided sense when outside acceptable range.
