Line laser

Preparation of an exhibition in the Cologne City Museum : A cross-line laser is used to throw a red cross made of laser light onto a wall. The light cross is used to precisely align the exhibition lettering on the wall.

Line laser with interchangeable lenses

A line laser is a laser with special optics that create a line instead of a point (as is the case with a laser pointer ).

Using lasers , projections of individual lines and multiple lines can be generated in image processing . While refractive optics are used for single lines (Powell lenses, cylindrical lenses), diffractive optical elements in combination with Powell lenses enable the projection of multiple lines and matrices.

Different optics create lines, crosses or other patterns depending on the application. Equipment for civil engineering and interior design project horizontal or vertical levels, with which the measurement of indoor or the leveling is facilitated of a small building site.

A line laser is described as an "extended source" according to the current laser standard EN 60825-1. The risk class is determined accordingly using a correction factor, which can be found as a formula definition in 60825-1. In contrast to a regular point laser, a "focused source", a line laser may have a higher optical power in order to still be classified in laser class 1 or 2.
