Title: METHOD FOR PRODUCING A LASER MODULE OF A LASER LEVELLING DEVICE, AND LASER LEVELLING DEVICE
Abstract:
The invention relates to a method for producing a laser module (32, 32a, 32c, 32d) of a laser levelling device (10), the laser module (32, 32a, 32c, 32d) being provided to generate a projectable laser line, in particular a laser line projectable over an angle range of 360°, and having at least one laser diode (18) for emitting laser light (20) in the emission direction. According to the invention, the method comprises a method step (116) in which a beam splitter (38, 38a, 38c, 38d) of the laser module (32, 32a, 32c, 32d) is produced by means of plastic injection-moulding in one piece with the laser diode (18), in particular in an interlocking, frictional and/or integrally bonded manner, in the form of an inverted cone (40, 40a, 40c, 40d) designed for total internal reflection.
