450nm laser pointer VS 650nm laser pointer
First and foremost, you need a clean application. Low-power red, blue and green laser pointer are commonly used for classroom presentations, lectures, presentations, power points and business meetings, where a laser pointer with a short-range visible laser beam is sufficient. Green laser Pointers in the 50mW to 150mW range are always very popular with astronomy. The bright laser beam visible ahead is very useful for astronomy researchers, astronomy enthusiasts, stars and star demonstrations. On the other hand, high-power red, blue and green laser Pointers are mainly used in military battlefield, scientific research, medical treatment, shooting, thermal experiments and other recreational activities. Therefore, you always need to have a clear understanding of the type of application you need.

Most people are surprised by the relationship between the power of a laser designator and the output power and wavelength of the laser. What color laser pointer is the most powerful? Laser Pointers of different wavelengths emit different power and energy at the same output power. First, the greater the laser divergence Angle, the closer the target distance. The low beam divergence laser shows better directivity than the large divergence laser. Powerful laser beams damage people's eyes and skin. Low penetration laser designators perform well in laser energy density. However, there is no absolute relationship between laser wavelength and transmittance. Of all visible lasers, long-wavelength laser Pointers are more transparent than short-wavelength ones. But the long wavelength infrared laser is affected by heat and the transmission intensity is weak. CO2 lasers can carve glass, but 532nm green lasers cannot.
