In the field of scientific research, laser pointers are widely used in optical experiments to test the reflection, refraction, and scattering properties of materials. Its stability and accuracy make it an ideal tool in optical research. Scientists also use laser pointers for laser ranging and spectral analysis to obtain precise information about the distance and spectral characteristics of objects.

The laser pen is designed to be compact and lightweight, easy to carry and hold, and convenient for users to use anytime and anywhere. In addition to basic indication functions, some laser pens also integrate functions such as page turners and remote controls, which are suitable for various demonstration scenarios and improve the efficiency and convenience of demonstrations. There are various colors of laser pens available in the market, such as red, green, blue, etc. Users can choose the appropriate color according to their actual needs. Laser pens of different colors have differences in visual effects and applicable scenarios.

The laser pointer is designed to be compact and portable, easy to operate, and can emit a laser beam with just a gentle press. The laser beam emitted by the laser pointer has high brightness and good directionality, which can clearly indicate the target at a long distance. Laser pointer is a convenient and efficient indicator tool with broad application prospects and market demand. During use, users should comply with relevant regulations and precautions to ensure safe use.

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.
