Line laser
A line laser is a device that employs a laser and an optical lens to project the laser beam as a line rather than a point (e.g. laser pointer). This may be achieved by passing the beam through a cylindrical lens or a Powell lens.[1]
Line laser with interchangeable lenses
Depending on the application, independent line lasers may be used to generate lines, or multiple line lasers may be used together to produce crosses or other composite patterns. In civil engineering and interior design, line lasers are used to assist in levelling building sites and structures.[2] Multiple lines may be generated for use with image processing.
Applications
Laser alignment crosshairs projected by a ring light which is mounted to a stereo microscope; the crosshairs facilitate rapid component location when transitioning between microscope and direct viewing
