Is the 0.5 mw laser pointer useful?
In any case, looking directly at the laser beam, whether 1 MW, 15 MW, 100 MW or higher, is very dangerous and may cause permanent damage to the eyes! It's faster than you think! A few milliseconds is enough. Even the singing of human eyes is not so fast! So be absolutely careful! Do not shine anywhere near human eyes! If a very low output power is selected, the laser beam cannot be seen at night and during the day. The beam of 532nm green laser pen up to 30MW is clearly visible. During the day, you can even see the green laser beam indoors. A laser indicator with a higher output power produces a stronger and stronger green laser indicator beam.

Material
The blue violet green laser pointer is made of 405nm blue violet laser diode. It is a semiconductor laser close to ultraviolet light. Low visibility, but can stimulate fluorescence. It is applicable to banknote inspection and chemical inspection. The spectrum of the yellow laser propagates between 589 nm and 594 nm, and manufacturers have always wanted to effectively reproduce these amazing colors. This is achieved by pumping IR laser diodes into crystals and optical arrays to achieve a wider laser spectrum. If you have any questions, you can ask us and we will reply to you as soon as possible.
