Not the same as other presentation tool, the operation of 5mW red laser pointer is much more easier and more convenient. It uses alkaline battery as its electric power source. According to very easy insert of two pieces of AAA batteries, it begins to generate highly bright and visible red laser beam in use. Comparing with the brightest 532nm green laser pointer, this red laser pen gets even lower power consumption. As a result, in common laser beam emitting work, there is always no need to make laser pointer power off, but still getting highly stable red laser beam emitting in use.
Owing to its longest development history and quite mature 650nm red laser diode tech, 5mW red laser pointer is able to support longer time continuous red laser beam emitting work. For instance, after its easy insert of 2 pieces of AAA batteries and simple press on on/off switch, it projects red laser beam with high brightness. It would be better to get 10 seconds cooling down, thus making sure of the best work condition of red laser diode and electric driving circuit board.
If 5mW red laser pointer is used for quite a long time, with the constant temperature increasing of laser pen tube, it might be power off automatically. The internal thermal control system makes sure of automatic power off of laser pointer, thus making the best protection of inner parts perfectly.
