The wavelength of light emitted by the green pen is 532nm, the laser type is Class IIIA, and it uses two no.7 batteries. The brightness of the green pen is objective, so the risk to the eyes is relatively high, the higher the power, the more dangerou ...

p>The word Laser (commonly known as "Laser") means light waves produced or amplified by stimulated radiation. high powered laser is an intense, highly condensed, unidirectional and monochromatic light beam, both visible and invisible to the naked eye ...

Laser features: high brightness, strong monochrome, good parallelism. It has a stable frequency, but it can have a lot of specific frequencies, so it can have a colorful laser. The color of the laser depends on its wavelength, which in turn depends o ...

Laser Pointers have been used in conference rooms for years and can be an effective tool if used properly. Recently, due to price cuts, these devices have been widely sold as new devices, and there have been some complaints from attendees about their ...

Laser speckle effect when the high powered laser to optical rough surface (i.e., the average fluctuation is greater than the wavelength of surface) on, because on the surface of a large number of random distribution of surface element scattering by t ...

Laser diode. Green light is generated through an indirect process that starts with a high-power (usually 100-300 mW) infrared AlGaAs laser diode operating at 808 nm. The 808nm optical pump is a crystal made of neodymium-doped yttrium provanadate (Nd: ...

p>Green laser Pointers are always designed in pen style. In the laser pointer recommendation, select only the air cooling system. In every continuously operating laser age, the laser beam is always very stable and visible. The operation is also very ...

People familiar with blue laser Pointers generally have two different attitudes toward laser minions. First, it does not require a laser pointer and is dangerous to the human eye. Laser enthusiasts who hold the second opinion think that laser Pointer ...

People familiar with blue high powered laser Pointers generally have two different attitudes toward laser minions. First, it does not require a laser pointer and is dangerous to the human eye. Laser enthusiasts who hold the second opinion think that ...

Play with the balloon. Black or other dark colored balloons are the best choice. Black is very convenient for the operator to pop the balloon well, because it can easily absorb enough energy in a very short time. When the red laser pointer was pointe ...
