Factors Affecting Laser Pointer Reach
Factors influencing a laser pointer’s reach include its wavelength, power, divergence, and atmospheric conditions. Wavelength determines the laser’s color and penetration through different materials, with shorter wavelengths like blue and violet traveling further in air. Power, measured in milliwatts, directly affects beam intensity and, hence, distance. Divergence, or beam spread, affects the laser’s focus and … Read more
