OPTICAL TRANSMISSION BODY MODULE

摘要

PROBLEM TO BE SOLVED: To provide an optical transmission body module in which NA of light outputted from an outgoing edge of the optical transmission body can be reduced. SOLUTION: The optical transmission body module 10 is provided with seven bundled optical fibers 11 and an optical transmission body 12. The optical transmission body 12 transmits light inputted in an incidence edge 12A by closing it in an optical transmission area and outputs it from the outgoing edge 12B. Each optical fiber 11 has an end surface 11A arranged opposite to the incidence edge 12A of the optical transmission body 12. The cross section of the optical transmission area at the incidence edge 12A of the optical transmission body 12 is≤1 mm2and larger than the cross section of the optical transmission area at the outgoing edge 12B. The NA when light within a wavelength range of 390nm to 900nm is outputted from the end surfaces 11A of the optical fibers 11 and inputted in the incidence edge 12A of the optical transmission body 12 is≤0.25.
