Red Laser Pointer - Knowledge and Tips for Buying
The Main Features of Red Laser Pointer
The wavelength of a red laser pointer is typically 635-660nm. The technical requirements of red laser pointers are generally not very strict. For this wavelength range, semiconductor technology and materials have matured. For less than 500mW, the production cost of a red laser pointer is usually lower than a green/blue laser. If you need a powerful laser and want to save money, red lasers may be suitable for you.
Applications of Red Laser
Before buying, you should know the different applications of different power ranges. If you want to use a red laser pointer to burn things, the output power should be ≥ 200 mW. For presentations or cat toys, low-power laser pointers will be better, and they are usually very cheap.
Precautions
If you need to buy a powerful red laser pointer, please follow the safety instructions, or it may cause unexpected injuries. Never make the laser beam enter the human eyes, which may cause blindness. Don't use a powerful laser to point the aircraft, which may cause serious accidents! Please keep the powerful laser pointer away from children, and do not use it as a cat toy!
