What is a green laser?
Green laser has greater versatility, strength and brightness than traditional red lasers. This laser color can be made in a small hand tool that looks like a miniature flashlight. Amateur astronomers often use a green laser because they reach so far into the atmosphere with a visible beam that you can point out stars and galaxies. Such light is said to be "collimated" or is made in a column. Different colors of light and lasers are determined by the size of these small waves, called wavelengths. The popular red laser has a wavelength of 650 nanometers that perceive our eyes in a visible spectrum as red. Green light, however, has even more energy in the wavelength of tiny nanometers 532. First, green is closer to the center of the visible spectrum, so it is easier for our eyes to easier to color at night. Because it has more energy, it can travel further and project a small dot on low clouds and far from the slopes 9,000 feet away (2,740 m). This tool can form a visible beam even without fog notOr dust to exaggerate him. The green laser looks up to 50 times clear than the equivalent of the red.
During star parties, court astronomers using small binoculars prefer a green laser that would point to a particular constellation, galaxy and stars, because the beam goes so far into the sky. The green laser is particularly compatible because it does not interfere with dark adaptation or how our eyes become more sensitive to muted light in the persistent darkness. Astronomers will decide on the strengths of around 5 million, a high performance laser. Yet machines that provide entertainment laser light shows can use much weaker force, such as 1 Milliwatt, to reduce the potential of damage.
The formation of laser beams from laser diodes is complicated. Special crystals must filter and focus light to get on the right wavelength and perfectly collimated. JuneLasers use laser diodes with direct injection, but the green laser requires more steps, so they are more expensive. Then this process can be firmly checked. Some models allow you to pulsate light, so it is released in Ostroz and creates a dotted line. Others allow you to concentrate the green laser, so the circle creates a small dot regardless of the distance of the object on which it falls.
The use of a green laser, as well as a red laser, requires safety measures. Even a quarter of a second exposure to your eyeball can permanently damage your retina. Never stick a laser along the ground where he can meet cars, people or pets. Buy power compatible with the intended use and don't let the children play with lasers.
