Remote green laser pointer, a new type of patented electronic product especially designed for computer and multimedia projector, has gain in increasing popularity in Eupropean countries and America and other developed countries. Apart from its mapping function of being used as a traditional teacher’s pointer, it also serves as a tool to wirelessly remote control computers and multimedia projectors.
When adopting RF, the signals will be transmitted through radio wave. It has no directivity, need not to be restricted by the mode of “face-to-face”, the distance is long enough to reach tens of meters. As long as there are no metal shielding obstacles between the emitter and the receiver of the remote laser pointers, RF can work smoothly. RF products usually have higher costs, but they have no directivity, are more user-friendly, thus more popular among customers.
While adopting 2.4 G technology, the optical resolution of the laser pointer will be up to 1000 CPI. Owing to the adoption of photoelectric technology, it will be more convenient for users to locate the target more accurately and flexibly. The laser beam of the remote laser pointers is very stable, electricity-saving. Besides, the sensitivity of the delicate parts inside the laser pointer won’t reduce as time goes by. Therefore, there is no need to take apart it and clean it. However, as a kind of new rising technology, its cost is considerably higher than other products
