Laser pointer, also known as laser pointer, pointing star pen, etc., is a small handheld laser emitter. It uses laser as an indicator tool, generating high-intensity beams through internal laser diodes for long-distance, high-precision indication in various occasions such as teaching, scientific research, demonstration, and tourism. High brightness and directionality: The laser beam emitted by the laser pen has high brightness and good directionality, which can maintain the clarity and accuracy of the beam at a long distance, making it very suitable for long-distance indication and explanation.

Laser pointer is a small low-power laser that uses laser as an indicator and belongs to general household items. Laser amplifies or oscillates light in certain excited substances through the principle of stimulated radiation, forming a high-intensity beam. The laser pointer contains components such as laser diodes, batteries, switches, etc., which are controlled by circuits to emit laser beams.
