Where can I get the cheap 5mw green laser pointer?
Laser diode is the main part, but it is not always cheap and sometimes not easy to buy most parts for assembly. DIY is recommended only when you want to make special or high-power laser equipment. Whether it's a high school science project or playing at home, laser is the perfect choice for all kinds of scientific experiments. Suppose the condensed light is so powerful that it tries to be strong enough to illuminate matches or burst balloons. Input high power laser pen. With a beam intensity of 200 MW or higher, you can do this and do your own research at home. In addition, various visible colors are within the visible spectrum and produce light of all wavelengths and colors we see. This can be explained by several different beam colors. For example, 532nm green laser, 450nm blue, 405nm purple, 650nm red (not to mention all visible colors, infrared and ultraviolet).

Generally, the crow driving green laser pointer indicator is 5-7 times brighter than other visible laser colors, but has the same MW output power. For clarity, the brightness of 100MW green laser is about 7 times that of 100MW blue or purple laser. This is because green is the brightest color for human eyes, which is generally the brightest color. This is also one of the reasons why plants and chlorophyll produce green. Green is obvious at night, in low light, fog or dusk (and laser color). The biggest difference is that it is very cost-effective, provides more visibility at a lower cost, and is more suitable for daytime use.
