Lazer pointer

A Laser Pointer is a compact, portable device that emits a focused beam of light, typically used for presentations, demonstrations, or as a tool for highlighting specific points in visual content. It usually operates with a small laser diode and can come in different colors, with red and green being the most common. Some models may also feature adjustable focus to control the size and sharpness of the beam.

Laser pointers are often used by teachers, lecturers, and business professionals to draw attention to particular areas on slides or diagrams. They are also employed in various recreational activities, like guiding pets or marking objects at a distance. Many models are powered by batteries and feature ergonomic designs for easy handling. Safety features like low-power output or a key lock may also be included to prevent misuse.
