Introducing the extraordinary 30mW Green Laser Pointer for Astronomy, this is a very effective tool for astronomy and teaching, as projected in the night sky a green line appears to reach the stars.

20mW Green laser Introduction

Development of the first generation of laser pointer nbsp; single 100mw laser pointer refers to a single laser function, regardless of whether the pen can write, whether it can stretch to become the pointer, but he always based laser functions as the main body, the price more than a dozen dollars, tens of dollars of such laser pointer and children's toys at home is no different, most get a little pattern on the pattern of the laser spot, such a laser pointer gradually be eliminated. Ordinary laser pointer laser pen pointer second generation nbsp; combination laser pointer extending other electronic functions on the basis of ordinary laser pointer. Launch the third generation of laser mouse nbsp; interactive laser pointer another technological innovation, will operate a computer and write green laser 300mw , I first saw this product, it was a new technology amazed this little guy is very powerful from a positioning composition and laser pointer, either directly by remote control using a laser pen can draw write, you can directly use the laser pointer at a projection screen or writing on the wall projection,

but also to operate a computer. The laser pointer integrates many shortcut keys, I did not carefully understand so many function keys, the experience of the long-distance remote painting write, write and operate a computer screen painting three functions, in addition to the write track curtain painted relatively slow, the other The function was normal. Such products currently on the market are mainly ViewSonic ViewPen and Skywalker whiteboard, obviously is a laser pointer, I do not know why is it called the whiteboard, but the price is also expensive, from 3000 yuan to 7000 yuan offer both.

Green high power laser pointer. The 532nm laser beam that is nearly 8,000 times more powerful than the sunbeam.We present various models of this effective tool for practice and teaching of astronomy, as projected in the night sky a green line appears to reach the stars.

It is also used in other disciplines, such as construction, medicine and tourism, where required point and show distant structures, or rugbygeneration a bright laser. It generates a bright green dot.
