People are confused about the principle of green laser pointer

There are still a lot of people who are confused about the principle of  green laser pointer . 20mW to 50mW of power is more appropriate, more than 50mW of power in the indoor dim conditions are particularly harsh. The price of the laser pointer with its bandwidth and stability, the narrower the bandwidth, the more expensive price, but the human eye can not distinguish this bandwidth gap, therefore, more economically strapped friends choose to power 50mW below, the price less than $ 100 laser pointer is more appropriate. In addition, the laser pointer power consumption generally in line with the principles of environmental protection and savings with a pair of good rechargeable batteries is necessary.
Here is a brief review of the basic principles of remote control  green laser pointer .   In addition, many of my friends may encounter this problem: during the day with good refers to the star pen, how to night on the "no power" it? Refers to the star pen with laser-produced media, semiconductors, and various characteristics of the semiconductor is very sensitive to temperature at low temperatures, laser pointer can not work properly, simply hand over the laser pointer for a while, let temperature to 20 degrees or more, the pen will be able to work properly, if not, it may be time to replace the battery.
