When the first laser was designed to carry and it was published as the handheld laser gadget. It was the Red Laser Light. After the red laser was released widely, thousands of the diverse varieties of red lasers arrived and quit the market during the years. Over the years, cheaper lasers are produced. We have all seen a Red
Laser Pointer
in the movie or in personal uses. Because of the technological development, the red laser technology has arrived at a certain point for the first time. The higher power red lasers are widely obtainable at the different online stores. The design and the laser crystal behind the red laser are crucial. While choosing a Red Laser light, you need to think of its fashions, price and warranty.
Perhaps the green laser pen is the most used beam light in many activities, from various demonstrations to star gazing. One could easily explain any presentation to a wide audience. Constellations and stars could be more visible even on a very dark night. This helpful gadget comes in various models for unique purposes. Firstly, knowledge of these products is crucial in selecting the right one appropriate for your purpose of use. Being familiar with your goals would give you a precise benefit to make the best use of a certain beam light pen. Laser light technology has enabled many items to be manufactured. Your presentation or visual control of astronomical bodies would be enhanced if you get the right one. The green light offers the highest sensitivity to the naked eyes which makes this device appropriate for heightened visibility. It is also an ideal accessory mounted on a telescope to enable better alignment and directed viewing of the heavenly bodie
Third, what is the price of the 5mw laser you are looking at? Laser Pen Pointer are goods where price directly effects the quality of the item. The lower the cost of a pen, almost always, the lower the quality. So you will want to keep this in mind, a unit under $50 is something to be very wary of. The diode may be of poor quality or the casing manufactured very cheaply, a preferred laser price for a 5mw green laser is between $75-$100 on the open market today. Yes, there are pointers out there at a lower cost, but historically these lasers have been of a far poorer quality than their slightly more expensive counterparts.
The advances in laser technology application over the past few decades had made people wonder what life would be like if we had not discovered the beauty of the process. "Light Amplification by Stimulated Emission of Radiation" is a process which is now known as Laser. We can find Green Laser Pointer in multitude of consumer products such as printer, scanner, video CD, medical equipment, laser pointer, etc. Laser has not surprisingly become our faithful servant just like pen and pencil. The use of laser pointer for teaching and presentation is very much a routine. However, how many users are aware of the potential problems associated with its use?

Conventional laser pointer usually comes with a low-powered red laser. The laser beam of the pointer is generated by a laser diode which produces the red wavelength. Since the power of the laser beam is relatively low, proper use of the pointer will not normally cause any safety concerns. Recently, a more attractive green laser pointer is available in the market. The green laser pointer has a definite advantage over the red as human eyes' response to the green wavelength is far more sensitive than the red. The green dot appears much brighter to the audience than the red dot. However, the laser diode which produces the green wavelength is not commonly available and it takes a complicated set-up to generate the green beam. With the set-up, the power of the green laser pointer can easily go over 100mW, whereas, the power of the conventional red pointer is normally less
