Patent ID: 8011105

Claim:
A leveling and plumbing device, comprising: a frame; a body pendulously mounted relative to the frame; a laser module fixed relative to the body so as to be mounted for movement with the body, the laser module comprising a diode laser and a crystal, wherein light is emitted from the diode and passes through the crystal, the crystal converts a wavelength of the light emitted from the diode laser so that light emitted from the crystal is within the green light spectrum; a beam divider, fixed relative to the laser module as to be mounted for movement with the body, that receive the green light emitted from the crystal and divides the light into at least two beams, including a first beam and a second beam; a first line lens, fixed relative to the laser module so as to be mounted for movement with the body, the first line lens disposed in the path of the first beam; a second line lens, fixed relative to the laser module so as to be mounted for movement with the body, the second line lens disposed in the path of the second beam; wherein the first line lens is oriented to convert the first beam into a planar level beam and the second line lens is oriented to convert the second beam into a planar plumb beam.
