Laser pointers available in various shapes and sizes
Are Green Laser Pointers Dangerous? Are they more dangerous than red laser pointers? These are great questions in terms of student safety and understanding the science of laser pointer safety. The manufacture of laser products is divided into four categories according to the power of the beam. Beams for CD and DVD players are Class 1, minimum. Laser pointers are in class 3, industrial laser equipment is in class 4, and today, lasers, or rather devices that generate high power laser pointer beams, have become very common and are available in large quantities on the market in all shapes and sizes. In fact, these devices are so cheap today that even elementary school students use them as toys. At comparable powers of class II lasers <1 mW or class IIIa lasers <5 mW, the short answer is no, green lasers are no more dangerous than red lasers

After receiving the laser, we noticed that each unit contains a hard case and foam padding to ensure the laser remains safe when packed or stored in a BOB bag. He also noticed that we include two pins in every handheld and portable laser: the remote locking pin, which acts as a safety lock. If this pin is removed, the laser will not turn on. The output power of a laser determines the intensity of its beam. Laser pointers are divided into several categories based on their power. High power levels, measured in milliwatts (mW), produce longer range and brighter light. The size of the power determines its relative brightness, burning ability and safety level. The apparent brightness of an illuminated spot depends largely on the wavelength of the emitted light. Most devices work in the red spectral region, and the sensitivity of the eye decreases rapidly with increasing wavelength. A device with an output at 650nm is about twice as bright as a 670nm device emitting the same power, while a 635nm device is about twice as bright. However, shorter wavelength green laser pointer are generally more expensive. If the question is about how far the light from a laser pointer can travel, there is no limit to the correct answer, as long as the light is not absorbed or scattered by the atmosphere. However, as the beam diverges, the area of ​​the beam eventually expands.
