Abstract:
A collimator includes a capillary for holding optical fibers, a gradient index rod lens, and a cylindrical lens holder which holds the gradient index rod lens and has an annular end face connected to an end face of the capillary by an adhesive. By using the holder, the resistant of light power is improved and the degree of freedom of selection of the adhesive is increased.
