Could the light along a side emitting optic be a totally homogeneous?
Regardless of the assurances of several manufacturers, it is a total impossibility since it would clash with the laws of physics, as we identify them. Sequentially for an optic to display similar illuminance along a given length, this would have to be ideal: with no losses.
Immediately light is produced by an emitter starts to decay, in a same fashion so a bullet starts to lose speed from the moment this issue from the muzzle of a gun. This light is not similar inch by inch in an optic as this leaves the optical port of the illuminator: the farthest by the light source, less light, because of the attenuation of the optic.
