Abstract

A laser leveler includes a first member and a second member moveably attached to the first member and adapted to settle into a predetermined orientation with respect to a gravity vector. A transmissive optical component (34) is non-moveably attached to the second member (36) and operable to form an impinging laser beam into a substantially two-dimensional plane of a laser plane. A Source of laser light (32) is non-moveably attached to the second member (36) and non-moveably disposed to ensure an emitted laser beam impinges said optical component.
