Michale Green laser pointer is mainly used for pointing objects

In our daily life, the green laser pointer is mainly used for pointing objects. The bright beam of green laser pointer is visible for hundred miles far away, thus it has been possible to watch objects in a long distance. In the night sky, people can use a green laser pointer to watch stars since the green color is especially bright in the evening. In the direction of bright visibly beam, people can find stars clearly and easily which cannot be seen through naked eyes.

No need of waving arms hardly, people can just fix the beam of green laser pointer on a certain star and this high efficient tool has become a helpful gadget for those of astronomy hobbies and researchers. Also known as PTD, this therapy uses a drug called a photosensitizer or photosensitizing agent which is activated by a laser. The drug is injected into the body and is absorbed by all cells but crucially stays longer in cancer cells. The tumour is then exposed to laser light of a certain wavelength.

Class IIIb Lasers fall among one of the classifications of lasers. These kinds of lasers have strong intermediating power. The power is believed to be strong enough to pose hazard to naked eyes. It is highly recommendable to use these lasers with the help of safety gears only. Apart from it, there are further classifications of lasers. These are IR lasers, hand held lasers and astronomy lasers.The Laser X2 has been designed with the theme of steel. Both pointers as balls and the graphical interface has been generated with textures of real steel plates meticulously careful harmony in the decorative elements. 

With a laser, the idea is to have all of the light going in the same direction, right? That means that if you can see the laser beam from the side, as shown in this picture from Star Trek, and in pretty much every depiction of lasers ever, then something isn’t right! The light is being scattered out of the beam. If you’ve ever used a blue burning laser pointer you know that even though it gives off visible (usually red or green) light.

The light can travel an extremely long distance, but the further away you are from the laser, the more diffuse it will be; if you shined a laser pointer at the moon, for instance, it would not illuminate a single point on the Moon, but have its light scattered over a fairly substantial portion of its surface, thus making it impossible to see. The tightness of the focus of the laser - as well as how much distance it is covering through some sort of matter-filled medium - determines the area of the laser at any given distance.

With the appearance of large quantity of 3000mw laser flooded into the market, shoddy laser pointers also become a big question for customers that should be taken into consideration. A laser pointer at cheap price might be manufactured by shoddy laser crystals. It’s would be a nasty thing to choose a shoddy laser pointer since it is usually manufactured without infrared light, which is a potential danger to laser pointer user.
