High-diffusion-coefficient and high-brightness light source generation device
A high-diffusion-coefficient and high-brightness light source generation device comprising: a light source module, an optical fiber bundle and an optical fiber hemisphere emitter, wherein the light source module provides the optical fiber bundle with a plane light source having the same size as an end surface of an incident end thereof, the incident end receives light emitted from the light source module, exit ends transmit the light to the optical fiber hemisphere emitter, the exit ends of the optical fiber bundle arranged on a hemispherical wall of the optical fiber hemisphere emitter in an equal solid angle manner, an end surface of each optical fiber exit end located on the same surface as the inner wall of a hemisphere, a bottom plate arranged above an opening of the optical fiber hemisphere emitter, and an opal glass window arranged at the circle center position of the bottom plate.
