If we can see laser pointers weapons, then look like?

For the ideal of laser pointers, in an ideal medium (such as vacuum) in communication is clearly not to see, the laser energy was concentrated in the beam, you will see the target there is no sign of the flash and corrosion wear, we do laser spot welding is the case. Of course, laser spot welding and laser beam energy is very low. Laser weapon is not a level.

laser pointers1

If the increase of energy, we can see a line of laser pointers formed the roof of the building, such as many high power laser. This is the Tyndall phenomenon, light through the colloidal particles in the atmosphere, a part of the energy to the surrounding formation of blinding light scattering effect.

laser pointers2

But note that different material laser pointers excitation frequency generation are not the same, if not necessary, not necessarily just fall in the range of visible light, laser spot welding applications are not visible at this point even if the laser scattering cannot see.laser pointers3

If the laser pointers energy to continue to increase the laser level, laser energy can ionize the air in the atmosphere, at this time you can see the white light, red or blue purple (according to different laser wavelength and power, can refer to the color of lightning).

Ordinary laser pointers flashlight how to increase the power to make it destructive?

If you just want to blind it is much simple. Glasses then look, 1mW laser pointers will beat you blind, infrared light to make macular degeneration, congestion fundus. The normal pupil diameter of 2.5~4mm, according to the 1mW calculated in order to blind blind eyes, but also to reduce the aiming difficulty, laser spot criminals need a face so much. I press my head 150mm calculation, in order to get the same power density, the power required for the 2.5W. so a bunch of 3W light spot diameter of about 150mm, have been blinded or temporary blindness.

Visible light, especially laser pointers, green wave length will be first applied to the cornea, the release of heat energy is absorbed, will feel the burn. Then the effect on lens, and the lens to absorb a large amount of heat. So, green was hit, the pain in my glasses, a division of the example is that hot brother aching, and kept washing eyes.laser pointers2

Lucky, will slowly recover. But because the heat in the lens, will form some floating floc. To me a example of the teacher is to see things that have a lot of laser pointers, a small jellyfish in front of floating power. A lot of words, to do experiments with porcine eyeball examples of eye explosion.

Near infrared, laser pointers is not easily absorbed by water, so it will pass through the cornea, lens, fundus. Direct light irradiation caused temporary blindness in the retina, and fundus congestion began, swollen, leading to retinal imaging. It is not normal macular degeneration. The fundus of the eye blood clot will slowly be absorbed, but the visual part of the retina gradually homing. The permanent nerve is broken, leading to the shadow into a black spots.

How much time does a strong laser pointers cause irreversible damage to the eyes?

Laser pointers belongs to the low energy laser equipment, it is very safe and can avoid the electrostatic hazard of all. Here are a few applications of CLASS I laser: laser printers, CD player, CD ROM equipment, geological survey equipment and laboratory analysis equipment. In any condition of CLASS I laser will not cause harm to the human body or the skin. Use CLASS I laser device, without other auxiliary equipment safety.

Open laser pointers is very dangerous, and the laser scattering will produce eye injury. No open Class IIIb laser and telescope equipment. No matter what time viewing of the laser in the laser in operation and control, must wear gowns and goggles.laser pointers2

Laser pointers also belongs to the low energy laser (power LASS IIIA laser is a continuous wave laser, belonging to medium energy emitter (1-5 (MW). Using the example of CLASS IIIA and CLASS II laser is approximately the same, such as laser pointer, laser scanner. Open CLASS IIIA laser is very dangerous, all not in any case directly on CALSS IIIA laser. Do not aim at anyone’s eyes with a CLASS IIIA laser pointer. Prohibit the use of the telescope to watch CLASS IIIA laser. These are some must pay attention to the problem.laser pointers3

Industrial use of laser pointers can not look directly, because the laser cavity in the oscillation and through the focus lens to shoot, if the eye is just at the focus of the moment will be a small spot on the retina


In the laser pointers process, whether there will be a thermal effect, the thermal effect will have on the circuit board and components

We understand that has relied on machinery / plate cutting, manual cutting, PCB designers and manufacturers and other forms of traditional plate equipment is very worried about laser pointers will produce the bad processing. No wonder they will continue to focus on regional thermal effect of the laser, especially the influence on cutting in line in the vicinity of the components.laser pointers1

Especially for high risk near the cutting edge of the components are destroyed in the board process may be studied. In other words, the thermal effects of ultraviolet laser pointers line around to what extent, the thermal effect will damage the cutting line in the vicinity of the components?

laser pointers2

Laser pointers will not cause damage to the sensitive components or close to the wiring board. For the study of thermal effect of regional effect will be more in-depth, but the results of the present study, we can clearly conclude that optimization of UV laser parameters can control the thermal effect of the temperature.laser pointers3

When the plate processing, you can use the laser pointers to adjust 15W. and when processing flexible material you can reduce the laser power to 1W3W. when processing flexible material or a specific plastic, you can also use the laser scanning control, microsecond between each scan delay to ensure proper cooling of heat affected zone. In order to avoid the implementation of one-time energy enormous heat generated in the product above agglomeration, this heat affected by near control wire components are protected.

The laser pointers is writing on a multi – function, small array of dual – function LED that can emit light and respond to light at the same time
