How is the circular spot created?Updated 2 days ago

Most flashlights operate on the principle of total internal reflection using a reflector positioned behind the light source. The reflected light is then emitted outward through a typically flat, parallel disk without directional control. This can result in scattering and shading within the beam of light.
In NOBLEX flashlights, an aspherical lens is used instead of a transparent disk. This ensures that the light rays are precisely directed, creating a clean, circular spot.
