The measurement object is CD (compact disc). As shown in the figure, the data is recorded on the recording surface of the CD with a single stroke like a mosquito coil. This is called a truck. Viewed in cross section, this truck has a slightly protruding shape. In fact, this track is intermittent, it corresponds to digital data, but here we ignore the intermittent track. The track pitch is set to 1.6. Let's measure this track pitch. As a general rule of thumb, please note that lasers lower than 200mW cannot provide enough heat to burn, but lasers higher than 200mW generate enough heat to be regarded as hot lasers. This is very important. If you are looking for a Laser Pointer that can illuminate matches, etc., make sure that its power is at least 200mW.
Are you looking for high-potential lasers or infrared laser pointer crows to locate and aim in the army? Different laser tools will find different values for each army. This blue laser pointer has three different output levels, allowing you to choose the option that suits your needs. Low power, high power, strobe. Many countries restrict the sale of this powerful laser pointer. This limits the power level of the consumer unit to a maximum of 5 mW, providing many times that power level. The 532nm green laser pointer is the brightest light color in the human eye, but it is often misunderstood as being very suitable for engraving. The actual situation is not the case, because the color does not determine the engraving ability, it is determined by the force itself.
