Many laser module users are not aware that a laser beam exits a housing at a slight angle. Because the laser module appears to squint, the degree of deviation from the housing axis is also referred to as the “squint angle.” This phenomenon is most easily demonstrated when the laser module is placed in a prism and rotated along its own longitudinal axis. The laser dot describes a more or less large circle on the wall. This does not have any effect on the majority of applications. The laser is simply set up to hit a certain point
However, this target point often has to be determined first – as a direct continuation of an axis or of a solid frame. Then, a precision laser is required such as the LT-PLM series that LASER COMPONENTS has offered for many years. These modules have a squint angle of 0.05 mrad. The deviation of the laser beam from the housing axis is, therefore, just 5/100 mm per meter of distance as opposed to 8.7 mm in a standard laser module.
We have expanded our reliable range of products by a version with a 1 mm beam diameter at the exit point. This results in a dot on the target surface that is smaller and more precisely defined. Due to the higher divergence, the application of this version is reasonable at a distance of approximately 3 m.
For larger distances, the standard version with a 4.5 mm beam diameter is still available. Both beam profiles are available in a housing with a 24 mm diameter and an M12 connection or as a version designed for mobile operation in a 35 mm housing with an integrated battery.
