Claim Text:
1. A method of manufacturing a diode laser line projector device, said device including a diode laser generating a beam of radiation having orthogonal fast and slow axes, said device including a first lens having an acylindrical surface lying along a first axis, said diode laser and the first lens being mounted and aligned in an elongated housing along the propagation axis of the diode laser beam, said housing permitting the first lens to be rotated about the propagation axis, said method comprising the steps of: incrementally rotating the first lens about the propagation axis of the beam to vary the azimuthal angle of the first axis of the first lens with respect to the fast and slow axes of the diode laser; measuring the uniformity of the intensity of the line of light projected by the first lens at various azimuthal angles of the first lens; and locking the housing to define a fixed azimuthal position between the first axis of the first lens and the axes of the diode laser, said fixed position being based on the measurements.
