Good Quality Adjustable Focus Burning High Powerful USB Rechargeable Laser Pointer

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, also known as laser pen, pointed star pen, etc., is a pen type emitter that designs visible laser into a portable, easy to grip, and laser module (diode) processing. Early laser indicators often used helium neon gas lasers, producing lasers with a wavelength of 633nm. With the development of technology, laser diodes have gradually become mainstream, and various colors of laser indicators have emerged.
