10000mw blue laser pointer is to use laser as a tool for teaching. The length can be specified far enough, can replace instruction pointer and other tools, you can also use ppt slide show, etc. as shown by.
The laser pointer is currently the most red, green and blue is relatively small, and expensive.
The red laser pointer is easier to make a wavelength of about 600 Duo Nami, mature technology and sophisticated materials of semiconductor technology. The green laser wavelength of about 530 nm, currently strip semiconductor laser technology is not very mature, so the expensive, low-power green laser pointer.
RF wireless high power laser pointer by an RF remote control and a receiver (USB interface) consisting of the RF remote control with built-in wireless RF transmitter radio, using only the receiver to a computer USB port without having to install any drivers. users only have to click on the normal RF remote control operation of the corresponding function key can be manipulated for the receiver. And transmitters do not really reflect the wireless receiver alignment freedom.
Laser pointer only as shown by, you can also control up and down and ppt or black documents words etc., fast reading, there are mainly red and green laser pointer in the market, due to technical limitations and the cost, color blue, yellow, little, when you use the laser pointer, you can see the place tens of meters, which is often used as indicated by the laser pointer.
20mw 532nm green laser scope
Easier to make color laser pointer, wavelength of about 600 Duo Nami, mature technology, and sophisticated materials for semiconductor technology. The green laser wavelength of about 530nm, currently 30000mw semiconductor strip laser pointer technology is not very mature, so the expensive, low-power green laser pointer 5000mw. Overall, the difference is the process, the wattage (brightness), the color is not the same.
As with the blue good, there should be a finished product, but certainly not cheap, not to mention yellow. In terms of existing technologies and materials that may not mature enough, so rarely.
The wavelength of the light emitted from the green laser pointer is 532nm, the laser type is class IIIA, using two AAA batteries. Relatively strong green laser pointer brightness, so dangerous to the eyes when using relatively high, the higher the power, the more dangerous. Generally, 5mw is commonly used, the US market allows 5mW plus 5mw Rechargeable Laser Pointer need special approval to use while going through. In the country is not strictly limited, which we are asked to pay special attention to the safety of the user, not in front of the eyes or other vulnerable area, but also to prevent the reflected laser light enters the eye to through. Usually green with an adjustable focal length will double protect switch. 1000mw Green Laser Pointer Principles
