Power of Laser Pointer

With the development of technology, laser pointer has became one of the latest technical products, laser pointer finally applied in our daily life, while laser has been existed for almost 60 years. Laser is a mysterious stuff that seldom has people has a well knowledge about it, even though you own a laser pointer. So what is laser pointer? As per the Wikipedia, laser is defined as "light amplification by stimulated emission of radiation." And in modern level of science and technology, the stimulation is accomplished by diode. Diode is an integral part of laser pointer. Then what is the special light used for? Well, laser is used for a variety purposes according to its almighty nature. The purposes including pointing out aim in a presentation, museum interpretation, sales house sand table indicating, aligning materials at construction sites, guided tools. Play with pets at home. For doctors, it is used for cosmetic and surgical procedures. For workers, it is used for carve up and alignment. Laser is also being able to use in the hunting, hiking, shooting and the beauty fields. Many items you encounter on a daily basis use laser, including CD and DVD players, bar code scanner dental drills.

After a preliminary understanding of laser, it will have many help in the next introduction of laser pointer. Laser pointer is a small handheld portable device with a power source and a laser diode emitting a very narrow coherent low-powered laser beam of visible light, intended to be used to highlight something of interest by illuminating it with a small bright spot of colored light. (Wikipedia) Laser is divided according to its output power and wavelength. The output power is stated in type of milliwatt. Lasers are divided into different safety classes on basis of output power. The technical of output power as it relates to laser products is the power level of the laser beam. A higher output power is brighter than a lower output power. So does the cost. More powerful laser cost more. 

Thus far, laser pointer has the different output power from 1mW to 3000mW. According to FDA, only the laser pointer with output power 5mW below meet with the safety standards and available for market. But it doesn't mean that it is forbidden to produce or to own a laser pointer more than 5mW, that is quite a ridiculous idea. What the FDA means is to let users to pay attention to the safety operation. More than 5mW laser pointer will lead the unimaginable damage. 50mW is able to burn cigarette or wear out the balloon in a flash. Even not to mention your eye. But we truly need more than 5mW laser pointer. Take stargazing for example, 5mW laser pointer is difficult to clearly indicate. The higher the power, the bigger the energy. The high power laser pointer even be able to cut board and glass pane.

So is there an all-in-one solution? Maybe a pair of laser safety goggles can be easily solve our scruple. Wearing laser safety goggles can protect eyes. But at the same time, it is also need to pay special attention that don't shoot laser on the glaze with reflection ability, and human body especially. Power of laser is the most important reason that laser can be popular and can't be replaced.

Thus we should try our best to protect children to make sure they live in a safety and health condition. Children safety problem has always been paid close attention by the public. For it is well known that children are our future. In the children safety problem, children's toys security gets more and more attention. The plenty of children's toys accidents make everybody have recognition about it. Recently, FDA issued a draft guidance documents. The draft aims to tell public, children's advocates and children's toys manufacturers the attitude and policy of FDA in the treatment of children's safety. In the draft, the main aimed at the children safety is laser products safety issues. 

Laser is a high-tech product with inconceivable power. Laser safety standards are varying. Now federal law case specification stipulate that all laser products sold in the United States must com ply with federal performance standards of laser products. While FDA has no special regulation about children laser products. Recently FDA comes up with a motion to make meaning to the laser products for children and stipulate that the laser products must conform to the luminous limit of International Electro technical Commission Class 1. The FDA is still working for the rulemaking. The purpose of the rule is to courage manufacturers to follow the luminous limit of children laser products, for the sake of reducing the risk of laser toys. 

The draft refers to the toy designed, produced and promoted for the children under 14 years old. Such toys are equipped with laser, such as cap pistol with laser for collimation; the spinning top that can emit laser beam while turning; the handheld laser device like laser sword; the fixed cylinder that can emit jumped laser beam and also the entertainment laser with gorgeous optics effects. They are all the amazing laser products. FDA believe that the radiation quantity of laser must be inferior to the luminous limit of the federal laser products performance Class 1 or the level of International Electrotechnical Commission Class 1 , which set according to the operate, maintenance, service , disabled and damaged condition. Within these standards, the risk for the user is the lowest. The current standard has no special mention to laser, but laser is an important part, because it laser could hurt your eyesight.

Come so far, the cap doesn't stipulate that children laser toy must accompany with Class 1 label. While the opposite is, FDA encourages manufacturers to stick labels on products to make customers aware of the risk clearly. FDA indicates that unless the parts of toy with laser can be removed, as well as can emit laser alone, otherwise the whole toys shall be regarded as laser products. Relevant products must obtain product certificate. Children toy safety is waiting to be solved. Buying a safety laser pointer with FDA label is necessary.

New Type Laser Pointer with Laser Safety Key

According to FDA, power more than 5mW laser pointer will cause the damage to human body, especially the eyes those sensitive parts. But we do know that laser is not only with the own usage as pet's toy, the higher power laser as 50mW or 100mW can be applied in stargazing or some burn experiments for the amateurs, we can't ignore the necessary demand just in the safety side. But there must take some measures to prevent the damage it may occur. In the laser application of industry field, the engineers will have some professional protection measures such as the industry safety goggles and even the protection suit, operate above the reflective materials. But to the domestic consumers operate outside the lab, what should they do, or do they have the awareness to make those series of protection with the cost of much money? While there might be a disappointed answer. On the one hand, that customers have no aware of the safety awareness, on the other hands, the expensive additional fee. The rest of consideration should move to the responsibility of the producer. They have the total duty to project a smart and safety design at the bottom. On this occasion, the cost will be added, thus increase the cost of production. While we all know that the goal of the producer is to try to reduce the production cost thus make the products have more competitive. From this into consideration, only the idiot will add a safety measure on the laser pointer. There comes the problem and this question, Is there will be a kindly idiot to do the idiot things just for the sake of customers on the safe side? We all want a affirmative answer, here we do have such lovely idiots.

The laser designers invent dual laser safety key. Dual safety key and remote control connector ensure the most secured operation for all proper, non-commercial use. Anybody under 18 years old are banned, and a pair of laser safety goggles is a must. The smart design is like the below picture shows, with a red tail at the end of the laser pointer, the usage of it is like the key on the running machine. You must have a acquaintance about running machine. You block the clamp on your cloth and the other end of the string is link to the machine switch. If the accident appeared in the process of running, such as tumble, this string tie in my cloth is pulled and the switch will shut. Well laser safety key has the same operating principle. We can shutdown the switch quickly in dangerous situation. The new type laser pointer with dual safety designs, we just introduce on above, then here comes the next safety key part.

 As the picture shows, you can see a metal circle up the red button. It is safe lock. It is designed to prevent accidental incident that if the laser pointer is unexpected hold by child. This circle just likes the locks of a door, you can't open it without the key. As same as that you can't turn on this laser pointer with the key. Now you may have a clear understanding about laser safety keys so far. Do you want one such safety product?

There is only one place has such design, also it is a online shop that can meet everyone' s demands worldwide. It is Highlasers. You can just browse their official website 

www. highlasers.com. It has varieties of power and wavelength laser pointers, laser sights, alignments and so on for your reference.
