Diy blue laser pointer how to manufacture?
The directional light depends on the characteristics of the laser. Laser a laser beam that is fired in one direction with very little divergence, about 0.001 radians nearly parallel. The first man to use a laser on the moon in 1962, the moon is about 380,000 kilometers from Earth, but less than two kilometers from the laser point on the moon's surface. High energy density. The laser is not very powerful, but it has a high energy density (usually only a small amount due to its small range), which can be collected from a large amount of energy in a short period of time and can be used as a 200MW weapon understandably.

Use a 500mW laser pointer - the mirror emits a pointer or signal light. Any light-colored material can be used, such as tin lid, glass, a piece of metal platinum. The continuation of positive reflection occurs along a long line, a point being Morse code. Even if you don't know Morse code, free exposure is attractive. Either way, the laser pointer is a great use. Phenomenon integration: red and 5MW green laser pointer colorless colloidal eggs have light path, red red ink and red brown iron hydroxide colloidal have light path. Red light is absorbed by black ink, red and green light, black ink and red-brown iron hydroxide colloids are absorbed.
