The pointer is very bright: at 50 ft. it can still be seen in daylight. You might need a darker room to distinguish it at a farther distance. As expected, the laser line is more or less visible at up to 16 ft. The controls are pretty straightforward. There is a slider with 3 ...

Laser users are frequently arrested for aiming at airplanes or helicopters. It is surprisinglyeasy to find you. And as authorities take laser incidents more seriously, they are putting more effort into finding perpetrators: 1:Police helicopter is targeted by laser pointer on the ground. 2:Helicopt...
Attorney John Bash says 37-year-old Justin John Shorey of Schertz pleaded guilty Wednesday to aiming the pointer intentionally at the helicopter and its flight path on Feb. 17. The laser blinded the pilot and left him unable to fly for a week. However, he was able to land sa...
the PROSTORMER's versatility and reliability make it a top choice for professionals and DIY enthusiasts alike, standing out among toughbuilt cross line laser levels, best laser levels for homeowners, and other high-end rotary laser levels like the Pittsburgh rotary laser level, DeWalt green rotary ...
In this paper, we present the first realisation and experimentation of a new eye tracking system using an infrared (iR) laser pointer embedded into a wireless smart contact lens. We denote this contact lens prototype as the cyclops lens, in reference to the famous hero of the X-Men comics....
(He-Ne) laser is incorporated into the CO2laser and acts as a pointer. The low-intensity (0.8-mW) He-Ne laser has a wavelength of 6328 nm, which is within the visible part of the electromagnetic spectrum, and the light is red. As soon as the CO2laser is switched on, this visible ...
After wavefront correction using a deformable mirror, focusing with an f/1.3 off-axis parabolic mirror delivered a peak intensity of 1022 W/cm2 at 0.3 PW power levels. Technologies to improve the temporal contrast were investigated and tested. The origins of pre-pulses generated by post-pulses...
Out of all other energy density parameters (laser power (P), hatch spacing (h), and layer thickness (t)), they found laser scan speed (v) as a dominant factor towards grain length, which affects the final dimension of the part. Conducting microstructural analysis and mechanical testing on ...
A laser pointer is a small pen-like handheld device that uses a power source (usually batteries) and diode laser to produce a coherent beam of monochromatic light. Laser pointers are used mainly for highlighting a point of interest by using a strongly colored beam of light. Typical low-end ...
