Does a thicker fiber optic tail mean a brighter shine

Even though fiber optic tubes used in scope reticles are short and hair-thin, fiber optic reticles provide significantly brighter illumination than etched reticles, stemming from the concentrating effect of total internal reflection. This creates a glowing, high-contrast aiming point that allows for faster target acquisition than traditional iron sights. Optical cables are used in a wide range of applications, from internet connectivity and telephone networks to medical imaging and industrial. Optical fiber is a glass or plastic filament that transmits light – either from an ambient (e., the sun) or direct source (e. 5 mm to transmit light through the principle of total reflection. Nano optics is a great place to purchase some super bright fiber optics at a great price. [pdf]
