Laser pointers are hand-held devices available in different colours and emitting a low-power laser light typically in the visible range. They find applications where we need to highlight or pinpoint a particular thing like in Laser shows, concerts, educational and business presentations, etc. Laser pointers also make a potent signalling tool, even in daylight. Accurately aligned laser pointers are used as laser gunsights to aim a firearm as well as in optical alignment applications. Different wavelengths of red, orange, green, violet, blue and infrared too can be used as per application needs.
