Laser modules provide a clear visual tool for easy alignment by using spot, lines or cross optics.
Precision alignment is fundamental for many industrial applications. It helps to align textiles, position saw blades automatically in a timber mill or to align wheels in assembly and servicing in automotive manufacturing. Depending on what must be aligned and how the laser is visualized determines the wide range of requirements for this application.
Designing the laser to form a visual guide requires a highly visible laser, normally 635nm that provides a bright red laser beam, or 532nm that supplies a very clear green laser. In other applications, where a camera or similar detector monitors the alignment laser uses a higher wavelength, typically a red laser at 650nm or wavelengths in the near infra-red.
Optics are incorporated into a laser module giving it the clearest output which eases the alignment process.
For many applications, such as sawing timber or aligning paper in a mill, this will be a line output. Lenses are selected from a range of fan angles to give the best line length for set-up and design.
A cross is preferable in other applications, for example, aligning textiles. This allows an extra dimension in the alignment process giving more precision and improving accuracy.
For drilling applications and others similar to that, a spot output may be preferable. In these types of applications, you need to see exactly where you are drilling, and then ensure that you continue to follow a straight path. A laser module provides a clear guide throughout the process.
