Flip 200mw laser pointer function is also based on the addition of many

A typical representative of this product page as the promise of a laser pointer V105, flip laser pointer V610, it has a laser, on the next page, page down three functions. Followed by black, fast playback, volume control and other functions.
January, after the repair, the customer bear the shipping costs. For CD Xin bear the freight , please return shipping when the first advance. if to pay for items, we will be accepted.

1 page of the history of a laser pointer. Page history of the first generation of Laser Pointer The first generation of a single laser pointer laser pointer is a single-function laser pointer laser. This laser pointer is only laser function, laser emitted by the different colors, red laser pointer and green laser pointer into. A lot of schools have ordered green laser pointer for teaching.Red Laser Pointer as low cost, cheap, everyday application of the mainstream. Green green laser pointer more expensive, mainly used in engineering construction, and astronomical observations. Gradual increase in the application of laser pointer functions, such as combo with ballpoint pen features a laser pointer with U-disk, U disk laser pointer, with a retractable pointer, three-function laser pointer ordinary ball-point pen. Regardless of whether such a pen to write with U disk, it can stretch a pointer, but it always is the main function of the laser, from the indicative.The government organizations also have purchased green laser pointer for speech and training. Price of ten dollars, tens of dollars. Obvious scattering of laser energy decay slowly, usually exposure to 200 meters away you can still see the clear red dot. March 11, 2008 Taiwan's "election," Ma Ying-jeou who is unknown red dot, that is, such a laser pointer that is. Turn the second generation of second-generation laser pointer laser pointer laser pointer on the basis of the general increase in function of the remote computer, called the flip laser pointer. Turn Laser Pointer (also known as laser flip pen, wireless presenter, wireless presentation controller, PPT flip pen, etc.) flip laser pointer depending on the wireless transmission technology is different.What are the matters need attention when people use green laser pointer? Divided into two types of infrared and radio frequency. Turn infrared laser pointer remote control uses infrared technology to transmit signals, and use the TV remote control in life, DVD remote control, air conditioning, remote control of the same principle. A typical product is a promise to the V606 remote control laser pointer. Infrared technology appeared relatively early, mature technology, low complexity, infrared product prices are relatively cheap. Page using infrared laser pointer technology is relatively low price, usually in the hundred dollars or less. Because infrared light can not penetrate the object, you need visual transmission. In between the transmitter and receiver, can not have any objects blocking, use the performance of the receiver and transmitter to be aligned within a certain angle, only to achieve remote control page. Laser pointer to use radio frequency technology to transmit remote control signals.You may need to install a drive to use green laser pointer for the first time. Relative to the infrared technology, RF technology and 360-degree transmission diffraction, no direction, between the transmitter and the receiver does not need alignment. As long as the receiver is not surrounded or covered by a metal, can achieve the remote control. Flip 200mw laser pointer function is also based on the addition of many, the most basic function is on the next page function.
