Enhanced Light Scattering As the machine’s height increases, the light emitted by the red cross positioning light travels a longer distance. During this extended path, it encounters more particles like dust and microscopic debris in the air, which scatter the light. This scattering causes the light beams to lose their original alignment, spreading out rather than concentrating on the target, resulting in a blurry red cross. This phenomenon is similar to how car headlights appear diffused in foggy conditions due to light scattering by water droplets in the fog.

 

Light Attenuation As light travels further, its energy diminishes due to natural attenuation. With the riser base elevating the laser module, the light must cover a greater distance, leading to more significant energy loss. As the light weakens, the red cross appears dimmer and less defined, resulting in a blurry effect.
