Green Blue Laser Pointer 10000mw have a 532 nm wavelength, and are about 50 times stronger than red ones. They are viewable in mid-air, whereas red lasers generally are not, with a very long range of as far as 1.5 miles (about 2.5 km) in heavy darkness. Green lasers are more expensive than red ones, however. Even shorter-wavelength blue lasers are also in development. Just pressing one button, a presenter can clearly pinpoint to the audience the message on the presentation slide which is many meters away. The highly focused light beam generated by the laser pointer can travel a long distance without diverging and create a bright spot on the surface it illuminates.
The green dot appears much brighter to the audience than the red dot. However, the 5 in 1 Laser Pointer Green diode which produces the green wavelength is not commonly available and it takes a complicated set-up to generate the green beam. With the set-up, the power of the green laser pointer can easily go over 100mW, whereas, the power of the conventional red pointer is normally less than 5 mW. There is no shortage of video clippings in the internet showing what a powerful green laser pointer can do and it needs no further illustration about the damages a green laser point can inflict to our eyes and skin.
1000mw laser pointer red used in a malicious way or used for recreational purposes can present a significant risk to health and safety and is also prohibited. Unsafe laser pointer behaviour must be reported to the UNIRPA using the University's Health and Safety Incident Reporting procedure and forms.A laser pointer, or laser pen, is a small visible laser device designed to highlight something of interest by projecting a small bright spot of coloured light onto it. They are usually portable, low powered, battery operated hand held laser devices.
PowerPoint includes pointers with pen and highlighter effects that leave a colorful trail. Adjust the PowerPoint options to show the pointer continuously on your slide’s content. A keyboard shortcut creates a High power green laser pointers effect in bright red, blue or green for viewing on a monitor or a projection screen.650nm beam light red laser pointer pen silver office/school presentation product description 100% brand new,never used item's color might be different from the picture because of the aberration.
