Light bar is one of the types of glass fiber, lined by a bunch of multicomponent glass fiber wire melting and carefully, can be
used to spread the light transmission and low resolution image, its advantage is wide spectral range, optical transmission
efficiency is high, the output facula equalization, temperature resistant performance is good, mainly is suitable for the original
light, tail cone receive concentrating light rods can obviously improve the light output. Lens such as plano convex,plano concave,biconvex,biconcave. Telescope :binocular telescope,digital camera
