ABSTRACT:
This invention discloses a dual-fiber optical collimator. The collimator includes a dual fiber pigtail and a GRIN lens wherein the dual fiber pigtail securely fixed to the GRIN lens by a ultraviolet-curing epoxy and a first heat-curing bonding epoxy. The collimator further includes a glass tube securely fixed to the dual fiber pigtail by a second heat-curing bonding epoxy. A stainless steel holder securely fixed to the glass tube by a third heat-curing bonding epoxy. The first, second and third heat-curing bonding epoxy is a heat-curing epoxy of 353ND epoxy. The ultraviolet-curing epoxy applied between the GRIN lens and the dual fiber pigtail is an ultraviolet-curing epoxy of ECI4481 epoxy or an ultravioet-curing epoxy of OG154 epoxy. The stainless steel holder securely fixed to the glass tube by a third heat-curing bonding epoxy is disposed a distance away from the first heat-curing bonding epoxy and the ultraviolet-curing epoxy.
